HM-Sen-MDIR-O-2: How to know if it is still powered ? (battery dead)

[chercheur]

Hello,

Detectors like the HM-Sen-MDIR-O-2 have no integrated battery check but I would like to find a way to automatically know if they are "still alive".
Would you know a way to do this by running, for example, a program once a day that would report all the elements that are "non responding" ?

Thanks in advance !

Hello!

They maybe don't have a voltage readout, but definitely have a "low battery" data point, so a service message is generated when the voltage drops under the threashold.

but I would like to find a way to automatically know if they are "still alive".

Usually the devices send a status message in given time periods (from about 1 hour to about 24 hours). If the CCU misses this status messages again a service message is generated.

Tx for your reply.
That is strange....I've removed the batteries from the detector when I posted the previous message so more than 24h ago and the CCU shows no service message.

This is what's available today:

It is still just as if the detector was up & running.

Regarding the low level there is absolutely nothing to configure for that model.
Is the low level voltage fixed in the firmware ?

Yes, that's correct.
The HM-SEN-MDIR-O-2 has no cyclic timeout

And no "low battery" data point in my opinion.
