threeway switch traveler system

[Sprokkie]

Hi,

i want to control light in a room with domoticz and the threeway switch.
The wall switch is a threeway switch so i can buils a travelar system
Walswitch and relay witch changeover contacts together is should work as a traveler system

Now i encounter the problem that the actual state of the light is not corrensponding wth the lightswitch icon in domotiqz.
So i added a 230v -> 3V optocoupler system and read the acutal state of te light in to domotiqz.
Send the actual state with the IDX number of the domotiqz virtual switch.
When i test on a breadboard the domitiqz icon switches acrodingly to the state.
If i turn on the lghts wiht the wall switch the relay is switched back by domotiqz

Any idea how to solve this ?

i used the words threeway switch and travaler system from wikipedia: https://en.wikipedia.org/wiki/Multiway_switching

Are you using MQTT to update the switch state? I had a similar issue and had to update domoticz only without triggering the On/Off action. I used MQTT: Topic: domoticz/in, Message: {"command":"udevice","idx":140,"nvalue":0}

yes i use the mqtt how do you send trhat command from the rules section ?

yes i use the mqtt how do you send that command from the rules section ?

What do you mean with 'rules section'. What I do is every time there is a locally wallswitch command, I update the switch in domoticz via domoticz/in with the new state without triggering the On/Off action. Also every minute I update it as a failsafe in case something went wrong during the first update.
