@ILLI13 Did you find out how to reset the Siren? I did not get it to reset with 10 presses.
Yes. I had to login into my developer account and reassign the original DH to this siren. After that I was able to reconnect it to smartthings and then assign the upgraded DH again.
Works great! I have ZM1601EU, branded by Clas Ohlson.
does anyone have issues with battery status. even though i replaced the batteries.
it seems to keep pinging me that the battery is low?
