Fibaro FBGS222 multisensor and 1Wire

Hi,
go a new FGBS222 willing to replace my espEasy Mega device connected to a 1Wire chain with 4 DS18B20

configuration on HA went good, BUT…
no ds18b20 are shown… at least I only have an Internal Temp sensor
If I connect only 1 probe I can see it, but if I add another both disappear… :frowning:
is anyone in my same situation?
thanks
ciao
