1Byone Doorbell (type O00QH-0013)

[planetf1]

I have a somewhat similar device - OUKQH-0499 which is their garage alarm, so rather than a bell push it contains two PIR sensors.
Domoticz & my rfxtrx433e (latest fw) picked up the pir sensors just fine, however I'm unsure how to add the "alarm".
The PIR sensors show up as "selectplus", but I think this is ByronSX, so I figured I'd go into switches, manually add, select byronsx and make up a unit code etc, then send this whilst the alarm unit was in learning mode. However this doesn't seem to work - no confirmation from the alarm. direct pairing with the PIRs work fine

Any ideas how I setup the alarm as a domoticz device?

I then tried rfxmngr & noticed that BOTH IR units were giving SelectPlus unitid 00D7C5 - I can transmit this and the alarm goes off, however I cannot seem to "learn" an alternate code, even 1 digit different.

I also bought the same Byone / Select Plus doorbell and I can let the (alarm) bell go off using domoticz.
Now I would also like to use the doorbell button in domoticz to set one of my virtual switches, but cannot get it working.
Looked into this forum, but can't find the answer.

The doorbell button is recognized and listed as device in Domoticz and I even can see it light up in Domoticz when the button is pressed. However, the doorbell is always ON and I can't get blocky in Domoticz to recognise when the button is pressed.

Has anyone figured out how I can trigger a switch using this doorbell button, which seems to be always ON?
