I flashed mine with Tasmota, it wasn't that difficult, just the same as flashing any other SONOFF maybe you were looking at an older guide. I mainly use mine to detect when the £16 doorbell is pressed. Go on Matt flash it!
Thanks for the vids.
With that encouragement... I have little options left but listen. I'm surprised how many of you actually is using it. Definitely RF433 isn't in the past just yet 😊
😊
I also hacked mine with tasmota. I can now send and receive RF signals from devices around my house. I use tasmota rules to control timing and payload issues. I particularly like to use RF magnetic contact switches that have separate open and close codes.
Do they advertise on contact only or update from time to time the state?
@@notenoughtech only on contact, rf devises do not advertise usually, sure not the door Reed ones, I've them too
I use the GS-WDS07 Wireless Door Magnetic Strip 433MHz from Banggood. It sends different RF codes for open and close conditions. It doesn’t send regular status codes. Using tasmota rules I publish Open or Closed changes via MQTT to node-red. So following an Open notification I have to assume it remains Open until a Closed notification is received. I have had a look at the tasmota rules documentation and can’t see how you could poll the switch given it can only send and not receive RF signals. Others may have more knowledge of the rules.
@@briandurward One of the advantages of Zigbee is constant communication, it's not perfect if you are looking at battery use, but it has its benefits. I know "skipping a beat" is unlikely to happen with RF but i had a couple of misfires with the RF remote so I was wondering.
@@notenoughtech Have you had a look at the RfCode command in tasmota. I can use it to send RF codes to RF devices like plugs that can receive RF codes to turn ON or OFF. I would be interested to know if zigbee can do the same.
Have you not looked on the web to see how many 433mhz products there are it is mindblowing and with a bit of work they will all work with the RF bridge so I would say it is very relevant in 2020
Considering that most of companies move to ZigBee, Bluetooth or low power WiFi rather than introduce new RF designs... I say they less relevant each year
@@notenoughtech They have only changed to Zigbee as they use their own code to lock you into their products but they can't do that with 433mhz so it is just another trap by manufacturing companies! look at how many Zigbee products don't work with other Zigbee products
There are lots of things u can do with it after it has tasmota put on it. This is especially the case if you bought lots of RF plugs/bells/pir sensors(non-sonoff) etc. in the past.The advantage of RF is also low power usage as wifi is not needed.You can also get 10 button rf controllers from aliexpress. I use the remote to switch off/on my light if I get up after midnight ( sometimes I am up late and want the light on). I use one remote to control my sky box in the sitting room to adjust the channel etc that is sent around the house via anolgue aerial signals also. You can use it for panic buttons etc.
Mine is Tasmota. Allows me to use cheap RF door and motion sensors, as well as cheap RF buttons and light switches from AliExpress. All on battery power.
For example, I have two tiny RF buttons next to the bed, talk to the bridge, talk to Home Assistant. Sends the house to sleep, then wakes it up.
Looks like there is a couple of you keen on flashing it.. in all fairness you all make it seem definitely worth playing with :)
@@notenoughtech Very much. Pinky Wafer has a way of getting ESPHome on it too, but requires a hardware hack. Wish I'd done that now, save having to reboot Home Assistant every time I add a switch to configuration.yaml.
I also found it can receive payloads from a cheap RF remote for plugs. Going to try broadcast to the actual plugs next, and if successful bring them out of retirement.
@@Kosh42EFGA couple of google searches... and this is another rabbit hole I will end up in eventually :) thanks for the tips !
Can you do a video comparing sonoff rf, sonoff zigbee. Snzb 01,02,03 devices and sonoff rf pir2, pir3. Wifi door window sensor.
Battery life.
Signal range.
Bridge device count.
Encryption.
Future compatibility with Home Assistant.
Extended battery hacks
To compare battery life you need a test environment. With battery life on these lasting in excess of 6 months it makes a bit more effort than its worth it.
If you are interested in range then ZigBee isn't the protocol for you ... For the range you probably want LoRa... As if you bind all sensors only to coordinator you are not building up your mesh network and use the protocol against its strength.
Count depends on the mesh... Again hard to compare as adding routers simply increases the capability of the ZigBee mesh. limit applies mostly to direct children.
I don't use HA so not sure how I can be any authority on that topic I'm afraid. If you want to go beyond 6months battery on ZigBee sensors use AAA OR AA batteries as they can replace CR2032 (you'll need enclosure customised for it)
@@notenoughtech can a rf door sensor tell is it open or not like a zigbee sensor?
They rarely do as they are design to broadcast only on change. So while they are dormant they don't broadcast
Thanks 🙏🏼. That means its better to use zigbee as final decision
I have a broadlink RM pro which does the same sorta thing with the addition of also doing IR. It also talks to google home so i can control any sonoffs directly and anything on IR/RF via the broadlink from the home app/by talking to my home devices.
I was thinking to try one of the broadlink devices... Figured will get a sonoff first and see how useful it is
I have the plus and the mini. Unfortunately they are a little harder to integrate into home automation and they are useless for monitoring devices like leak detectors. That's why I bought a Sonoff as a supplement to the Broadlands devices.
Jump on ZigBee bandwagon ;)
After flashing mine with Tasmota, I pick up 433 Mhz signals from all of my neighbours. And what's worse, I can send those signals too without knowing what they control. Long story short, I like having the small fob to control my lights, but I wouldn't trust it for anything security related like doors, etc.
Yes, replicating the signals is definitely not the hardest part for better or worst. I hope you are still friends with your neighbour.. otherwise he is in trouble hahah
In the long ago times lots of garage doors could be cloned. Newer garage doors use a more secure protocol but there are lots of the old ones still in service. Just for kicks I hooked my SDR to my external antenna and looked at the 433mhz RF signals in my neighborhood. Lot's of them out there. I was thinking of trying to identify what the devices are.
Just imagine placing a probe for 2 weeks harvesting the data then walking down the street opening the doors one by one like in some insane villain music video 😍😍😍
@@notenoughtech I was thinking I could fairly easily add a LNA (Low Noise Amplifier ) to the Sonoff so I could pick up more signals from further away. What you describe would be interesting but I won't be doing that. I value my Ameteur radio license too much. I had of course thought out how that could be accomplished and came to the conclusion the easiest way would be to make the Sonoff portable with an external battery. Alternatively someone could just use a high power transmitter or an amp connected to the Sonoff.
@@notenoughtech Given your comment you should see this video. th-cam.com/video/CNodxp9Jy4A/w-d-xo.html
Can I learn RF remote signal of an unbranded LED Strip using this SONOFF RF Bridge and control the LED strip using the SONOFF bridge by passing voice command to Google home mini or Alexa?
I wonder if you could sync a car alarm remote to the bridge, and arm and disarm a car alarm within the Sonoff Bridge’s range?
They don't work the same way. Car alarms usually and encoded code that changes on a rolling basis
@@notenoughtech good to know👍
Thanks for the clarification
Any time!
Literally just ordered one, want to use it to control my 433MHz RF Controlled Projector Screen.
Oh I sense fancy automation. Check out my smarter wall switch article to find out how to trigger it when you turn on your projector
@@notenoughtech The hope is to tie it all in via HA/Node Red and Alexa to the Phrase "It's Showtime!"
If you can wake up the projector with a voice command already ... :) use ping to check if projector (if connected online) is awake then you can dim the lights and retract the screen). For my projector, I just use the remote to wake it up, everything else happens automatically
Sonoff have updated their RF bridge now in a white box!! I cannot find decent instructions to flash this with Tasmota. Any chance you can Matt?
Very unlikely if I'm honest. I have little incentive to do so as I have no RF at all in my home
I'm looking to replace 8 regular wall switches spread through the house with RF433 switches. I would like one button strategically placed on a wall to send an RF signal that results in turning on or off all 8 lights at once. My understanding is that a regular RF transmitter button cannot be paired with 8 devices. Can I use the Sonoff RF bridge to do this? Or will it only send out one signal at a time? Incidentally, I would like smart functionality as well, like a timer to trigger the turning on or off of this set of lights.
dear friend i liked your video and i need your help, i bought few years ago a chinese home alarm system it is working on 433 i have motion/door sensors and i want to connect on that sonoff bridge do u think is it possible?
Thanks for the video Matt,
You are quick :)
That's what she said.
Haha.... I fell for it...
hacked mine with tasmota, now i can use a generic remote to trigger the other sonoffs in my house if i don't want to use voice :)
i use tasmota websend command on rf bridge to recall other tasmota devices by ip, so no mqtt or controller is even needed...
From a couple of comments I see that people do like to flash it! I have 2 RF devices I could control (that are linked anyway) so I'm not sure if I should do it... Although having this work with more RF modules is tempting
@@notenoughtech as you are not going to use it so much anyway, why not hack it? 😬
I'm sure at some point I will... Once I run out of Zigbee hacks... :)
Can you do a comparison between the RF bridge and the Zigbee bridge from Sonoff? Also, how does the latter compare with the Tuya one?
I don't think the comparation between the Zigbee Bridge and RF bridge is needed as they perform different functions. Tuya Hub vs Zigbee Bridge - I may do that one!
Hello,
I follow your channel and I am very pleased with your videos.
Is there a way to ask you to make a video, how to hack sonoff bridge, work with more than 4 sensors? This will certainly be useful not only for me but also for many of your followers. Thank you in advance!
I don't plan on at the moment. There are instructions on GitHub I know that these are a bit hard to follow but due to my time constraints and lack of RF devices in my ecosystem I don't think I would revisit this any time soon.
Consider ZigBee devices
@@notenoughtech
Thanks for the reply.
Subject:
Consider ZigBee devices
Would you share your opinion about the future of this technology? In this case, isn't this an aging technology?
Google and Apple joined ZigBee alliance. I think that's a good indication that protocol isn't going away
Hi. Nice video. Can you tell me is there any difference between the white zigbee bridge and the black? Which one would I need to control sonoff dw2 rf door sensor?
They use different protocols: black = RF, white = ZigBee
@@notenoughtech I see now. Thank you. Shame that they cannot integrate RF in the zigbee one
Have you tried paring non Sonoff products that transmitt 433mhz ? I wonder if it's quite straightforward? Thank you
No I'm sorry, I don't have any :(
Thank you.
Always a pleasure :)
Hi, your video is great. I'm setting up one of these, the 4 buttons are programmed and when each button is pressed on the app, the RF red LED flashes but it fails to do the function that was asked. I'm puzzled🤔🤔🤔
Is the remote you "copied" paired with a target device?
@@notenoughtech Yes, it works fine. I've just tried another one button remote to another device and that ia working brilliantly through Ewelink...
🤷♂️
@@notenoughtech thanks for your reply though 👍
Thanks, how do I switch off the sonoff bridge without powering down? It is working as an alarm that cannot be put off which is a pain, when I am home or has to keep going off because I am there, unplugging the unit doesn't sound right, what should I do
Take a look at automation tab in eWeLink you will be able to set schedules for your sensors.
Came here looking for a comparison of zigbee and RF. The search continues.
ZigBee introduces better security faster data transfer rates mesh network and more IOT compatibility. RF has better range and better low power usage.
@@notenoughtech Thanks! I'd still be interested to know technical implementation differences.
@@haley8004 as the name suggests it's the frequency of the radio 433Mhz Vs 2.4Ghz and all pros and cons of higher frequency waves
I just ordered a zigbee bridge but I'm wondering if RF is worth trying. Not using wifi is important because I saw a consortium of doctors claiming wifi is a "probable cardinogen".
@@haley8004 neither RF or ZigBee is in the ionising spectrum so you don't have anything to worry about. The evidence in that regards well documented. I recommend WHO study on the subject which uses data submitted by 38 countries, rather unverified claims over studies or animal cell tissue which made the news with doubtful claims.
How to add sonoff mini to a bridge and a remote
Sonoff Mini doesn't have RF, but you can use the automation panel in ewelink app to create an action on your Sonoff Mini coming from a RF remote
Isn't OpenMQTTGateway the way to go?
That's something I need to look up for sure thank you
Hi,
What would be the easiest method (without FW flashing) to have the garage door status Open/Closed status indication?
I was looking at Sonoff RF Bridge and Sonoff DW1 door switch but DW1 only gives an alarm when the door opens (no feedback that the door has closed back or status O/C).
Are there any compatible wireless door sensors that provide Open/Closed status?
Integration with Google Home mini to query door status would be beneficial but door O/C status on the phone would be enough.
Thanks.
This would be good for you notenoughtech.com/home-automation/sonoff-wifi-contact-sensor/ it's in preorder now and only $7
@@notenoughtech Thanks.
It looks just right since it's simple to mount and it doesn't need any other hub/ bridge to display status in the app. Now I'll just have to wait for it's relase :-)
Almost there. I will have the commercial sample for testing as well. The one you seen in the link is a dev unit. The final shape is square as seen in the poster.
Hi. I got a came gate controlled by an RF remote. Would this bridge work to control my gate online?
Without flashing tasmota, Sonoff limits the RF products this bridge can be used with. If your gate has switch that can be operated by a RF sonoff then yes, otherwise you would have to flash it to assure compatibility with your current RF system
@@notenoughtech ok thanks. Not sure if understand it all but will do more research.
Hi I've ordered one of these RF bridges in the hope that you can switch a WiFi sonoff basic with an RF pir through the ewelink app anyone know it that's true?
Yes you can. That's what I did in my demo. The Sonoff light was not connected to WiFi, and i triggered it with RF433 remote and Sonoff RF bridge - it's like having a device which presses the RF remote buttons for you on location
Can I use this as an universal RF remote?
I'm not sure about the compatibility with other remotes. From hacking posts I found that once hacked you could use any RF signal in that range. Note you will need a remote to set the signal first. I'll try to get my hands on one to test
@@notenoughtechThanks for replying. I'm not very confident with flashing the device. Without doing any hardware level or software level changes, is it possible to learn unbranded LED strip RF remote signal and control it through the RF bridge using Alexa or Google Home mini?
The control part yes. As per "unbranded" it will vary from one remote to another. Even if I try mine... May not work for your model. It's a risk unfortunately
@@notenoughtech Can you please try to learn a Non SONOFF RF remote signal and using the signal please try to control a Non SONOFF RF device and let me know the result. thanks in advance
How to add mini device to a bridge
You will need a RF compatible device, I don't recall mini series being RF?
