Is it possible for remote wakeup a device to get the state-information?
I use three smokedetectors “Heimann HS1SA-M”.
To early detect a battery-failure I check the battery-messages. If there are no messages since five days I make an incident. For two items it works. The third item does nothing.
If I make an alarm-check direct on the item - it sends the status information correct.
Thanks for answer
