I have just bought a Razberry and two PAN04 (In Wall Dual relay(1 way) switch module).
At first, both ones was included on the same ID : when I switch the main power on, both entered in autoinclusion mode simultaneously, so I had to cancel autoinclusion on one, and let the other include with the Razberry.
When I tried to include manually the second one, the green led switch off immediately, the Razberry did not interview the PAN04 and did not really include it, so I had to retry the inclusion a few times before it worked.
Is it normal ?
When I switch the main power off, both PAN04 seem to forget that they were included : as I turn the main power on, their led blinks indicating that they are back in autoinclusion mode...
Is it normal too ? Will I have to reinclude all my devices every time I power them off or on every power drop ?
Thanks in advance if you can help !
