The fact that you can mess with the BIOS remotely blew my mind. I’ll be looking into this.
It's really awesome to see the stuff that's traditionally been only accessible to data center workers making it's way to homelabbers at a comparatively reasonable price point.
Typically you would either a BMC that support remote KVM, a system that has a serial port and the required firmware to do something called console redirection, or a commercial KVM over IP solution which is a lot like this only a LOT more expensive.
For my home lab, I specifically went after a Super micro board because when they integrate a BMC on the server board, they also provide the KVM over IP capability without locking it behind a license and/or add in hardware. But it means having to compromise on price and the hardware generation of the equipment to find affordable second hand boards. I would have considered different hardware choices if this was available when I was building my home server.
FYI, that is also possible with Intel VPro with AMT Enabled machines. It supports most of the mention function like pi-kvm but stuck with internal display
A KVM wouldn’t be a KVM if you couldn’t do that.
But the fact that this lets you connect optical/USB images as though they were actual devices to the managed machine is the icing on the cake for me.
Hey Jacob - you should check out Jan Mortensens TH-cam channel th-cam.com/users/JanMortensen-s2dvideos
@@splynncryth Homelabbers don't need it at all. If they needed it so badly, they would have spent the 600 dollars for a real KVM over IP solution, and even more, invest thousands of dollars in their server system. It will pay off when customers rent their space. People who run home labs are not serious at all about their system. They don't care about their amateur infrastructure, thus ignoring the necessity of a cheap KVM over IP solution. The only real benefit of a cheap KVM over IP is perhaps, better video streaming? I know those professional ones are not very good with video streaming, but they will catch up since we are at a very early stage of this innovation. This cheap KVM device is a great idea for a security standpoint, where you want to remotely access one physical computer connected to an offline private network.
This pi-kvm looks so cool!
BLIKVM IS A RPI Compute Module 4 IO Board for PiKVM th-cam.com/video/aehOawHklGE/w-d-xo.html
Can you do a quick video of you actually plugging the kvm into your computers? Would be curious to see exactly how that works
It just works once you have the PI running.
I would also like to see how this connects to a PC or server, especially if the PC has a VGA port
@@rudiahlers You'd need a VGA to HDMI adapter.
Thank you, good explanation and back story in the beginning, was very interesting
I'm excited! Not only do I have a couple of boxes running various shit, but also a couple of NVRs. While the NVRs have a remote app, you can't do some stuff that you can only do while at the NVR itself. It's a pain in the ass to climb up into the attic (which is actually climate controlled) to do some things.
Thanks for this! I'm on the wait list to order one now.
th-cam.com/video/aehOawHklGE/w-d-xo.html
I'd like to see you connect this KVM to an older enterprise server that uses VGA. How does this device manage powering an enterprise server on and off? This solution would be very useful if it worked on the older enterprise computers that have old iLOs using old Java and active-x which are no longer supported.
Ditto. Exactly what I'm interested in using it for. Got several Dell R210/R710/R720 servers as well as a mix of others.
Wondering if a "simple" VGA to HDMI converter would work for the video part.
Another software licensing question. Docker is free for personal use and there is licensing for commercial use.
Open Source Plans :Docker is proud to support the Open Source community.
Qualifying OSS projects can get no-cost Docker accounts to support their contributors and end users.
Does Pi-KVM have a signed agreement ?
it was awesome, congrats.
I'd like to know if you think that would be OK working using a VNC connection through a Pi KVM, in terms of keyboard and mouse speed using Internet to work in day-by-day use like text editing.
I don't think, that in current state Pi-KVM is a good fit for daily texting or so due to huge screen refresh lags... I'd suggest to use VNC servers for that.
Currently, I'm using TightVNC server on Windows and perfect Remmina remote desktop client on my Linux setup. Remmina allows to perfectly tune remote desktop view, in fullscreen mode, the desktop looks exactly like you're working locally.
I am interested in the hardware side...how everything was connected. that's a cool project
looks great 👍👍
been waiting for this, also replaces the overpriced usb iso stick
I think I missed something.... how is he controlling the hdmi switch input? I'd love to see how that was wired up.
From microusb to usba to the pi
@@NovaspiritTech oh awesome. thats really useful!
Have you tested the remote serial port capabilities? That would be really nice to see.
this is insane, nice video, nice product
th-cam.com/video/aehOawHklGE/w-d-xo.html
I already have a POE hat on my PI. Is it possible to connect with different ports?
In the video, it seemed like the FPS is always less than 10. But I think you said it can get to 20. Can you confirm?
It’s a great improvement over pikvm on a zero w that gets 1 FPS or less on wireless, but had hoped for ver 3 to get 30 FPS at FHD.
Pi-KVM uses framedrop if the image does not change. FPS in the interface means the actual number of frames transmitted and displayed in the browser. This saves traffic. If you try to watch the video, you will get 25 FPS.
What a great video
I don't understand why someone would give this a thumbs down. Great content brother.
My God that thing's cool
Hi, i need a variant for dual monitor setup. Is there any posibility to set this up withs Pi-KVM?
many thanks
It is sad that there is another company selling this exact software after he developed it. Tinypilot is selling his hard work for $70.
tiny pilot is actually using the ustreamer software pi-kvm developed.
@@NovaspiritTech I know it is sad because they are selling it.
I can see all the work done into this that is impressive. But you can find a great Raritan single ip kvm for under 100(used).
@@DrLoveQc I do not think raritans ipkvm compare to this pikvm. just think security. then how many options you have .. you could even have 10 ISO files in rspi4 for whatever OSes.. sky is the limit
Hi, I’m just curious if this is possible using a old laptop instead of raspberry pi 4.
Impressive! But... "you could do anything you could do if you were sitting at the computer" sounds much closer than VNC to "physicsl access." I get that that is the advantage, but that also seems like it could open up some serious security concerns.
"Given physical access to an office, the knowledgeable attacker will quickly be able to find the information needed to gain access to the organization's computer systems and network." - Gregory White
a.k.a "With physical access (and time), NO computer is secure."
Thoughts?
You can't do without this near-physical access if you need to remotely fix a broken machine that refuses to boot. So you have to compromise. Pi-KVM tries to be as secure as possible, but you can also use a VPN, for example. Everything is in your hands.
ok but why is the font Comic Sans?
This is amazing.
How does it affect usage if you wanted to use the device in person? Like does it add lag if you were to set this up on your main computer and use it daily and have it as an alternative way to remote in.
Great video. Could you use a VGA to HDMI adapted with that USB/HDMI switch to connect to an older server without HDMI?
Yup, a vga to hdmi connector is about $12
@@NovaspiritTech hey Don, have you noticed any flakiness with keyboard/mouse connectivity when switching between inputs with that Ezcoo unit?
I have seen quite a bit of reviews out there complaining about that for this model, so just wanted to see what your experience has been? Thanks!
I guess your intended audience is for highly technical savvy people. I am an IT business professional with decent hardware understanding in need to control a desktop remotely via KVM, but the way you present things and the way you jump from one thing to another or make long parentheses in your presentation, drives me off my tracks in comprehending what you are talking about. IMHO, it is not difficult to talk with a slower pace and possibly overlay some labels on each input on the HAT or explain the typical user scenarios of each kit. Showing drawings of the setup will also be of help to your audience; a picture is a thousand words. You ain't making it easy.
I agree very short on detail but then I don't think his intention is to educate - you may achieve better understanding by referring to the developer's GitHub page:
github.com/pikvm/pikvm
and pikvm.org
@@lordflinty sadly the pikvm website points to the same channel for learning about the product which is a dead end.
This look like what I am after. It seems the Ezcoo KVM switch you recommended is no longer available, is there any others you (or anyone) would recommend that would give me the full functionality?
Could you share that 3D model so we can print our own cases ahead of the hardware release?
This is that type of project that is going to be unnecessary constrained by ARM arch.. I wish developer realizes that is is worth porting to x86 SoCs (like e.g. N3150) which brings hardware flexibility for DIY route, more performance for higher quality streaming and is not that much more expensive as Pi4.
Please show the physical connections. I have done this and cannot get multiple connections to show

how to remote dual screen pc with 2 pi kvm?
Can I use two ezcoo switches with one pikvm if I need to control more than four servers? If so, how would the connections from the switches to the pikvm work?
Not right now.. honestly this is so inexpensive, just build 2. Bought that Ezcoo switch on Amazon for $76, HDMI-CSI bridge was $36, RPI 4B-2G is $35, your under $200 for a 4 port IP-KVM. FYI, the Ezcoo switch also works as a local KVM as well, just add a usb keyboard/mouse and an HDMI splitter for a local monitor

@@mwolrich Have you noticed any flakiness with keyboard/mouse connectivity when switching between inputs with the Ezcoo unit?
I have seen many reviews out there complaining about that issue with this model, when used as a local KVM switch.
damn fine videos
I just need something that I can use in a data center where there is no KVM available, mainly using a VGA connection. Can it be configured to do that?
You just need a vga adapter
The HDMNI-CSI-2 bridge is out of stock - can you link to another one?
th-cam.com/video/aehOawHklGE/w-d-xo.html
What Pi 4 RAM configuration is needed to run this well?
nope just need 1gb is enought... would work smoother with 2gb+
You were speaking way too fast without any sort of explanation of use cases for specific pieces of the hardware.
An example was the hdmi switch. How are you using that when you have machines 500 feet away?
My God that thing's cool - I had no idea it was this detailed and advanced, he's done some AMAZING work with this... writing his own video protocol, that's incredible. I really really want one of these, even if it were to just show it to business clients down the track. This is going to be in much higher demand with increases in telecommuting and remote working continuing after COVID.
Wow! This project (now product) has come a long way since I last stumbled upon it. I would like to have seen a bit more detail on the connections of all of "bits".
This is an amazing project. This guy has done some truely stellar work, and not only on the hardware, but also the supporting software he did... Truely will benefit the open source community. I will for sure buy one from him : i was considering it, but i did believe that it was one pi per machine, so it would end up being costly. Here i see that you can have multiple machines on one pi kvm? this is simply AMAZING.
By the way novaspirit, great chanel, you show really interesting stuff. I am quite pi savy myself, and often see basic stuff on chanels that talk about pi and sbc, yours is not that. One of my favorite pi chanels these days, with jeff geerling's. Keep up the good work :)
thank you very much!
Great Video. Do you know by and chance if an eight Port HDMI Switch would also work?
OK good job... Here's something that could use a little lab work / tryout... Interfacing to the newer Mac Mini's and whether you can reboot them with the (equivalent keys) hold down option (force netboot) or CMD+R (boot to restore mode). Interface is with USB (A or C type into Mac Mini)
Could you go into more detail on controlling the hdmi switch with the pi-kvm?
The HDMI switch can be controlled by IR using an extender and a remote control or by a micro USB port which allows you to go back and forth between sources
Is it possible to use other KVM's besides the EZCoo as long as it's hotkey switchable?
I don't see why not. So long as you can trigger the KVM to change from the pi, which can pretty much be done in all cases from IR control to I2C or USB.
Zerotier (VPN alternative) for PiKVM:
access via SSH: root root
su
rw
pacman -S zerotier-one
systemctl start zerotier-one.service
systemctl enable zerotier-one.service
zerotier-cli join YourZerotierNetworkID
zerotier-cli info
ip a
ro
Didnt want one cause it cost upwards of $500
*Pi kvm costing $450*
Hey can you show the TailScale function? Also, does this connect to WiFi networks? This would be great to leave at my parents’ home for remote hands-on with their computers.
i can show the tailscale on another video cause that requires a little bit of setup, and yes it can run on wifi
I would be curious to see if you can switch between systems with a hot-key sequence and how fast the switch is? In a manufacturing environment we have multiple computers communicating with instruments being produced and we're continually switching between the computers at one station as each instrument goes through testing, etc. It would be nice to see how easy and fast those transitions are...
Can you explain a bit on how you power on the machine? I think it was like 2 secs picture showing how you connected it to IPMI ( if i didnt hear it wrongly)
I'm trying to figure whether I could make good use of this when rebuilding my network in a new home and stuff.
Like, I'd love not to have the gaming rig in the living or bedroom but somewhere it can't be seen or heard a lot since I could use Parsec, Steam Link or Rainway to do stuff via network.
But doing that still wouldn't allow me to change GRUB settings from the remote system i.E. a ThinkPad.
So this still looks promising.
@ I was very happy that Linus did the multiseat setup which too inspired me to do my current system with two AMD graphics cards and RyZen.
But that doesn't change the fact that those fancy looking machines can be loud unless you have some expensive and potential risky water cooling going on.
Using really long HDMI and USB cables is one idea, yes but it's also difficult to do at a certain length.
Hello, i just look at your video about the pi KVM, and i was wondering if it can run up to 8 KVM, i notice that you are demonstrating the 4 port switch, so is it possible to get more port ?
Try playing Minecraft through it on a more powerful machine.
Edit: Also Port forward it through your router and try using It remotely.
@@schrodingersmechanic7622 it's httpS
I bought one here in canada. This is an incredible product, worth every penny even though it's 350CAD as a full setup with the metal case.
The ezcoo 4 por hdmi kvm doesn't look like it will be back in stock any time soon, if at all, can you recommend something else?
Is there another compatible hdmi switch? The ezcoo 4 is not available now.
Does other kvm switches(like the noname aliexpress) work the same way as ezcoo with just a usb cable? Or do you need to hook up gpio pins to the buttons for em to work?
And what I would love to see is use of usb relays / gpio pins in general.
Hi Novaspirit, question I have, is, when logging into the pi-kvm with the HDMI Switch (4-port EZCOO), is it possible to have another session at the same time (i.e. another person logging in and accessing lets say Port 1 while someone else uses Port 2 remotely)? The goal was to use this with 4 computers while myself and 3 other people log into the pi-kvm and work at the same time on separate machines in the same location (it could be with other logins created; not necessarily the default admin admin login). I imagine if this is possible, it would really diminish the ressources of the pi's processing and probably stretching it very thin. Thank you in advance for your feedback :). -Jason
Here’s a thought… Auto configure zero tier for auto vpn. This would give you the ability to configure one of these and send it wherever you want and it will automatically connect via encrypted VPN using UDP.
+1 this would be really nice. Zerotier for the win
Is the max resolution still 1920x1200@60Hz? Are there any plans to improve that? I am looking for 5120x1440@ 30+ fps.
I like your corner shelf, can you ship it to Germany please? 😊
Can anyone tell me which ezcoo kvm switch should i buy for pikvm? "KVM Switch Hotkey 4x1" or "KVM Switch without Hotkey 4x1"
Whats a KVM?
Anybody try connecting this to the older Avocent series IP-KVM's to use Pi-KVM to control multiple PC's? Trying to perform this now and running into a few snags that I was hoping to get some tips on. VGA to HDMI adapter for one, and then HID interface. Pi-KVM works fine directly on the HP Server, but trying to connect to the Avocent IP-KVM has got me a little stumped.
Nice video! Ofcourse the guy who made pi-kvm had to use Arch Linux...! The pacman -Syy is the wrong command, this only updates the package databases, you should have used pacman -Syu (no need for the double y, this force updates the database files)
Hello Everyone, I need some information on how does this Pi KVM works on the work laptop.
My work laptop is located in my house and I would like to travel out of the state without carrying a work laptop. But my office networking guys always monitor my location by checking my IP address and I cant use Team viewers or RDP or VPN routers to access my laptop due to security policies and VPN connection.
So I would like to use the PI KVM to access my work laptop remotely But I am a little afraid to do that because of the office security policy configured in my laptop.
1. I would like to know, Does my office IT security know if I connect this Pi KVM to my offie laptop?.
2. How does my work laptop recognize the Pi KVM HDMI and USB when connected to the laptop?.
3.Does my office laptop recognize the Pi KVM as a suspicious device?.
Could you please help me with my situation?
This sounds very much like what I'm looking for. I'm about to begin working (very, very) remotely from my office. I'd like to have a KVM-over-IP device that I can log into and have anyone connect a Mac or PC laptop to for me to troubleshoot or reformat. Have you (or can you) test this using this configuration?
Oh great no initial setup,,, I'll say with 75% confidence and 25% ignorance that no one is seemingly willing to make a walkthrough guide for a mentally inept asshats like myself? Oh well I guess the world just never meets a goober halfway!?!?
this project amazing, about feature how many pc can connect to one ipkvm-pi, and ist this support display port instead HDMI, thanks
My computer that I want to connect this too is connected over Wifi as my ethernet wires in my house dont reach that room. Can I also have my Pi-KVM in the same room running connected to Wifi? Does it have Wifi support basically is what I am asking?
I am sorry, but what even is this thing? I dont really get it. What is the point? This seems very high effort, specialized, and a cool use of technology to do something even greater, but what is it?
Import note from their website: "NEVER edit /etc/kvmd/main.yaml. Use /etc/kvmd/override.yaml to redefine the system parameters. All other files that are also not recommended for editing have read-only permissions. If you edit any of these files, you will need to manually make changes to them when you upgrade your system. You can view the current configuration and all available KVMD parameters using the command kvmd -m."

Is it possible to take an online call on a work Chrome Book remote controlled via Raspbery which is at home, on my other laptop that I'm taking with me while traveling, while using camera and microphone of laptop thats with me?
Just got to see this review and it's interesting to see if IODD ST400 could work with this as well. thanks
@Novaspirit Tech, the KVM featured is the model with the Hotkey feature?
Do you know of any other kvm's, ezcoo 4 port hdmi kvm, that will work? Maybe a 8 port?
Thanks so much for sharing.
Any chance the “story -> coming soon” link in the description from 4 months ago can get added? =)

You talk to much, don't waste our time just GET TO THE POINT!!!!!!!!!!!!!!!!!!!!!!!!
The EZCOO 4 port HDMI KVM link on Amazon shows "We don't know when or if this item will be back in stock". Any other source? Or is it discontinued ??
Got one on Amazon last week, so it is back in stock !!
I think it would be beneficial to see how this thing is hooked up to systems I want to control, didn't really see that in the video.
I would like to use this with my Mac laptop with dual monitor, can this be done?
You have to provide your own Raspberry Pi4B right?
Does it work in a Chrome browser in an Android tablet? How would you turn on a remote laptop?
Does this work for machines that don't have any kind of GPU?
NIce one, how does this compare to the tinypilot which is a similar idea?
Tinypilot uses the original software developed by Pi-KVM. In addition, Pi-KVM has no paywall, contains more features and released earlier.
Thank you for this one! I just bought the HDMI2USB adapter and I'm using it right now with a RPi4 and it's amazing!!! Thank you again for this review because I was looking for the expensive alternatives and I was depressed! Cheers! Thank you again! Take care!
Would be good to see if it works with a VGA adapter, as most servers aren’t on HDMI yet.
Would also be interested to see a PCAP of the connection to see ports in use, traffic stats etc. Thanks for the content and will definitely be ordering the full kit.
working on the pcap data of network transfer.. i'll post that up soon...... i found a vga adaptor to work on this for only $13 amzn.to/3oqUUw5
Will the Pi-KVM require the Arduino HID?
pacman -Syu actually does the upgrade
not -Syy....
Wait..the pi is controlling the KVM switch?!
any channel for buying pikvmv3 from china ?
