I am looking for a 4 channel 433mhz relais 24 volt, to be controlled with the RFXtrx adapter,
The purpose is to control Gardena 24V water valves.

Hope to find some answers this one below looks okay but I am not sure if the 433 mhz protocol is compatible.

The info states these use the EV1527 coding, this is widely supported by both RFXCom and RFLink so you shouldn't have any issues controlling these, easy way would be to capture the code of the remote with Domoticz and just use that, my only concern would be 433mhz stuff is one way communication so in the unlikely event the receiver misses the off (stop watering) command you might end up with a big water bill, a small lake or both !!

Edit, maybe one On command and at least 2 Off commands seperated by about 20 seconds just to be sure.

Hi,

Why not use a 4 channel Wifi relay, e.g.Shelly Pro 4pm. It is much more reliable, as it uses 2 way communication, so you can verify whether the switch has been activated/deactivated.

It is more expensive and this might be a show-stopper.

As you obvoously live in a Z-Wave device :D, you can also Google for a 4 ch. Relay on Z-Wave.

Regards
