@m26872 ok :-(

Indeed, I would use two different channels. The question remains which controller is used. I have two networks on my test-Domoticz setup which use different channels from my production setup. So I have nodes on 3 different channels. Domoticz handles this fine. I did not yet test the move of a node with known ID from one channel to another. When time permits I should check this ...

@doblanch said: if (state != laststate) { delay(30); if (state != laststate) { delay(30); if (state != laststate) why do you have these blocking delay()s? I would focus on non-blocking code for such a device... Are you using an interrupt? I think you need to post your entire sketch to get good comments

Yes of course...anyway "version mismatch" should not appear due to wire issue :-)

Hello, can you put the entire file .ino modified , I have the same problem as you. Thank you
