Doormaster not ringing any more


I have noticed that my door master does not ring anymore… It did work well for years.

Could it be that I changed something in the config that disabled the doormaster ring?
Is there a way to perform a kind of “selftest” function to check that all is well with the door master in general?


Ok, I found this after I posted my message:
MX-DoorMaster does not ring and/or does not open the door - Self Service / Troubleshooting EN - MOBOTIX Community

I’m going to get a replacement battery and see how it goes.
