Sonoff switchman M5-3C (same UUID as another bridged Accessory)
### What issue do you have? Please be as thorough and explicit as possible.
i have Sonoff switchman M5-3C and an older TX-3C
the older T3UK3C shows 1 master switch + 3 individual switches for each channel and it works flawlessly
my new M5-3C switches when they are imported i only get 1 switch (even though it is 3 gang switch) but it doesnt work  
and there is log messages about both switches (ignore the part where i have my older TX-3C switches disconnected)
