Great vid and nice to compare them! If only Shelly would listen and act to customer's wishes. Everybody complains why Shelly firmware can't save a config to an external file. For backup, for documentation, for interchangebility, for experimenting. But no. I asked them in 2020 and still nothing changed. My main reason to go to Tasmota. Also completely opposite to this is that Shelly does prepair for firmware changes by implementing a pinheader!? So why not implement config save/restore? I really don't get it. I do like Shelly over Sonoff because of their better resistance against lightning/interruption peaks/dips on the mains. Lost Sonoff switches several times where all the Shellys persisted.
I don't see anyone talking about the Access Point feature or the Range Extender. On the Shelly One Plus the AP is enabled and it will not let me disable it. It defaults to have the "Open network" box checked, but says "It is important to password protect your device's access point to secure your network from unauthorized access." If I uncheck the Open network box I can add a password, however it will not let me save the changes. To me this looks like a security risk. I have mine on a network that does not have access to my home network, but it seems like others could connect to the shelly and have access to other devices I have on that guest network.
One thing that's extremely disappointing with the 1PM is how inaccurate the voltage reading is. I have 221V mains and it displays 205V which must mean that the power reading is inaccurate too.
have you tried the shelly plus add on, thinking of getting one to hardwire my door sensor and temp humidity sensor instead of this zigbee battery powered devices, would like to see a video
so, could i theoretically make an environmental sensor for temp/humidity and then based on that data send the signal to the smart relay if outside of parameters? trying to automate my home garden and spent way too much money with AcInfinity just for them to be unreliable and have bad customer service.
Does anybody have experience with the life expectancy of HF7520 ( 6:56 in the video )? Depending on the frequency of switching eg 1/min -1/1hr is there any lifetime curve available for these? The reason is that I saw many faulty "smart plug" where the relay contacts were burnt after a year with about 1/hr switch rate.
hello, can I use this device to change the direction of the AC signal? I have an electrical Velux, and I need a switch that will help me to change the wiring in order to open and close the Velux accordingly... I do not know if you fully understand what I need, but I really hope to find the correct product for my need here :)
For stock usage it is great for pairing to a network as it removes the issues of dual band isolated same SSIDs. For after market... All kinds of cool sensors.
@@digiblurDIY yeah i actually found a video of someone who was able to make it work via Tasmota firmware after I left this comment. They did it by using a light switch to open and close a loop between Ground and GPIO-3 pins of the Shelly 1 to turn the relay on and off. It took many hours of searching to find that information so I hope it helps someone else here!
I did it way back in my original Shelly tips and tricks video. If you use mains power on the device you do need to use a mains rated switch to isolate things.
@@digiblurDIY for my situation I am trying to control the Shelly relay using a Raspberry Pi Zero, so I can't do it via AC power. I am trying to control the relay using the Pi's 3.3V or 5V port and a GPIO port.
I'm looking at your pinout and the order looks like it is almost the same as my USB ftdi module, I'm wondering if those pins would fit directly in those holes.
No they won't they are too big on mine. I had to buy a 1.27mm pitch pin header. The pins are 0.4mm square and they fit. Painful to solder, at least for me.
@@digiblurDIY Hey, can u please make a short video on how to flash them? I tried to get it working, but everytime I try it doesn't work. I use the pinheaders to connect an ftdi32 - perhaps i connect it wrong - don't know ... would be nice to get a video. There is no other video on youtube for the plus series. thank you!
I used thin resistors legs for flashing. They do the job!
Will you do another video when esphome is supported? Perhaps steps to flash esphome on this switch?
Esphome supports the esp32 solo chip now. You can even do a Bluetooth proxy with these now. I have the yaml on my website.
Thank you for the detailed video. Please let us know where is the antenna?
The wiggly trace on the end of the PCB
Thanks for the video! I'd love to see your take on using Bluetooth with these devices and making it usable within home assistant with usage cases
Have some footage coming up showing some BLE stuff on it.
can you flash it ota like the older ones👍

The pins are in the 50mil form factor.

I turn that off once I pair it with my network as I don't want open APs.
Thank you Travis.

I have only tried the built in integration for them myself but I still prefer having full control of things with open source myself.

Yes. I do this with my bathroom vent

thank you so much for your awesome video , have you tried to flash shelly uni plus ? also will the shelly add on work with tasmota ?
Not really sure, I don't have one of those or the Shelly add on.
Great video Digyblur and Great work Shelly!
Thank you! 😁
great job as always

In other words, can I use this Shelly Plus 1 as a DPDT rocker switch for reversing the AC signal that feeds my Velux... ?
Sorry not familiar with those myself.
感谢分享，我居住在中国，但是不好买到Shelly设备
I wonder if it support thread or matter in the future?
Thread will be zigbee so I'd say no.
Does anyone know how to mount an external antenna? My 1+ is sitting inside a metal box and the wifi is shielded pretty well that way :(
when internet goes off thee shelly resets the time and puts it to 0:0 AM how i can persist the time ?????
Point it to a local ntpserver on your network if you have issues with internet outages.
Did you have to do anything special to enter flashing mode, like grounding the GPIO-0 pin, or holding the button?
GPIO 0 to ground just like a regular ESP32
How did you flash tasmota? I'm having a hard time getting the chip ready for flash. Do you have to ground I0-0? I tried but still doesn't work.
What flasher is being used? Some do not have enough power.
Call me dumb, but.....what are the uses of the Bluetooth on the cip? What can you do with it?
For stock usage it is great for pairing to a network as it removes the issues of dual band isolated same SSIDs. For after market... All kinds of cool sensors.
Can the Shelly 1 or 1PM be triggered to turn on/off the relay over the GPIO ports?
I know it can be done with Tasmota firmware

@@digiblurDIY not sure if this would work to connect 3.3V and GPIO port from the Pi to the Shelly Gnd and GPIO3 port for controlling the relay on/off.
What do you say about the temperature when the relay is on? Compared to shelly 2.5 and 1pm in the original firmware?
I haven't compared the original firmware as I don't run it.
@@digiblurDIY Ok, then in comparison with the non-original firmware, what can you say about the temperature? 😊
I'm looking at your pinout and the order looks like it is almost the same as my USB ftdi module, I'm wondering if those pins would fit directly in those holes.
Need some super small pins. Even breadboard jumpers were a tad big, dupont is definitely a no go.
@@digiblurDIY
Maybe a bobbypin or similar? Safety pin-mod ?
No they won't they are too big on mine. I had to buy a 1.27mm pitch pin header. The pins are 0.4mm square and they fit. Painful to solder, at least for me.
That 1PM+ might short out. On that PM chip the bottom left pins aren't soldered cleanly enough. Check it!
On the BL0937 itself?
@@digiblurDIY yes, check minute 11:55 . Bottom left 2 pins of the BL. Seems to have some solder almost bridging both pins.
Good spot
On the regular one there also is a solder bridge on the topside of the ESP
Thanks
Before flashing to Beta, first test the device...
I did. It's not hard to flash back as well or even to Tasmota. I took backups of the original firmwares as well.

FTDI might not provide enough power for the esp32 to go into flash mode.
@@digiblurDIY do you not have pulled down the PU Pin to go in flash mode?
GPIO 0 pull down is still the normal.
These are crap
