Sonoff RF & Rfxcom

Post by GCB2016 » Friday 24 November 2017 17:57

Hi everyone,

I just received my Sonoff RF (https://www.itead.cc/sonoff-rf.html) and I am trying to get it to work, but I am failing miserably ;)

Just to make sure: this is about the Sonoff RF version, not the regular Switch. My assumption is that because this Sonoff support 433mhz and PT2262 and Lighting4 it is not needed to flash the Sonoff RF: Is this correct?

I have the following setup: Raspberry Pi 3, running Domoticz V3.8153 and of course a working Rfxcom (the 433E). I am already using it with several PIR detectors and KAKU devices. However I can't get it to work with the Sonoff RF. I am hoping you can help.

The Sonoff is added to my wifi network with the EWelink app and it is working through the app. So at least the Sonoff works. My next step was to add it to Domoticz. I went into the Switches tab and clicked 'Learn light/switch'. Domoticz goes into learning mode and I try all sort of things but nothing happens. I push the button on the Sonoff, I hold it for 5-10 seconds, I switch the Sonoff on/off via the app. Nothing.

Then I tried to add it manually, but I have simply no idea what to choose in the options. Can you help me figure out what I need to do?

In Domoticz > Setup > Hardware I made sure the RFXcom accepts Lighting4.

All the help is appreciated. Thanks a lot!

Is this a Sonoff 4CH Pro?
The buttons on the Sonoff 4CH Pro do not transmit 433MHz RF signals.
You will need the Sonoff remote for this. See also chapter 14.5 in the RFXtrx User Guide.

Hi B,

No it's the Sonoff RF https://www.itead.cc/sonoff-rf.html. Maybe it's new? Or I am confused?

It's like the switch but can be controlled with 433 rf signals. Please see the manual by RFX on page 44 http://www.rfxcom.com/WebRoot/StoreNL2/ ... _Guide.pdf

It looks like it should be possible without flashing the Sonoff RF? Thanks!

I am sorry, I did not see you pointed to the exact same chapter... So are you saying that for Sonoff RF I probably need the remote as well?

You can pair a Lighting4 device with this Sonoff.
The drawback is that thi device only has a toggle and no On/Off command.

You can test this also with RFXmngr, use a pulse time of 370usec and ID = D216B1

What do you mean with "You can pair a Lighting4 device with this Sonoff"? Do you simply mean it is possible to control the Sonoff RF with Domoticz (via the RFXcom?)

At the moment I am unable to use the RFXmngr (I am on a MAC). Do I really need it, or is it just for testing?

How would you recommend adding the Sonoff RF to Domoticz? Should I use a (Sonoff) remote? Or can I add it manually as a switch? (all these questions ;))

Thanks for helping me out!

It seems you need a Sonoff remote to create the device in Domoticz.
