Hello digi128pci
this post is very interesting. Did you get any furter? Can you post your findings?
Is there a way to see which sensor has issued an alarm?
Is there any byte encoded showing the battery status?
I have a set of similar smoke detetctors by Pollin (I assume that the cheaper ones are all the same inside, this is true for some very cheap and high priced standard smoke detectors).
I would like to decode the signal and at least know which senor has initiated the alarm and, if possible, get a battery level or at least a warning.
