Heiman smoke sensor beeping

Other Devices & Integrations Climate Control & Temperature Sensors

Hi,
I’ve got a few “Heiman smoke sensors”. Unfortunately they give a beep at irregular intervals of almost one 24 hours.
Any idea what this might be ?

Thanks,
Herman

Which model?
Often beeping means the battery is low.

Hey Django, did you ever get to the bottom of this issue? I have the same problem.

I have the same problem, but I can’t say exactly which smoke detector is causing it. Either it is one of the Fibaro Smoke Sensor 2 or a Heiman HS1SA. Some time ago there was a short beep every 24 hours (mostly at night). Now it only happens sporadically. But all batteries are full and there is no other message or anything like that.
I don’t know where to start either.
