P9 Yellow solid unable to reset
I recently acquired a 3 module Deco P9 system. Initialy all went well. Two days after install one of the decos went into solid yellow. I tried resetting through the app and physically through the hard reset hole. Nothing works. If I connect, the only thing I get is yellow solid, no blinking at all. It stays that way all the time. I need help!!
the serial number is 219BD26A02279 and its says its ver. 1.8.
I will appreciate any assistance. Thanks.
