Hi does Aqara Wireless Mini Switch, WXKG11LM work with just the hubitat
or is a Sonoff SNZB-01 better?
The Aqara device doesn't work natively, but there are a few community drivers floating around that it can work with. However, many Xiaomi devices (like this) are prone to "falling off" your network unless you use only repeaters/Zigbee routers that they are known to playing well with. Thus, they can be tricky.
The Sonoff device works with a built-in driver, and as far as I know, no one has noticed any oddities like the above. IMHO the biggest downside is that it's not as pretty.
