New Action door (deurbel) not visible

[locmer]

Hi,

I have a perfectly working Select plus (Action) doorbel (deurbel)https://www.action.com/nl-nl/p/select-p ... e-deurbel/ from about a year old. I wanted to add a second receiver to Domoticz so I can use that as a secondary bell upstairs. Somehow the new one is not seen by Domoticz. They look very much identical and I am using the same method to add them (learn switch). Any ideas, did the device change protocols?
