Domoticz

Bonjour

I have got a door contact DIGOO ,and Domoticz creates two devices instead of one !!!
in fact when we look at the trame ID is the same ,but Unit is different !!!! That why domoticz creates two devices and one is stucked OPEN and next one stucked CLOSE

Packettype = Lighting5
subtype = BBSB new
Sequence nbr = 33
ID = 07DD20 decimal:515360
Unit = 1
Command = Group On
Signal level = 6 -72dBm
------------------------------------------------

Packettype = Lighting5
subtype = BBSB new
Sequence nbr = 34
ID = 07DD20 decimal:515360
Unit =3
Command = Off
Signal level = 5 -80dBm

Is there a way to try to do understand to Domotics that is really the same device ?
Have a nice day
