Some real mixed reviews there, and a scene controller that needs a neutral wire!
There are better options in my opinion. Any button controller in HE can be a scene controller. If you’re specifically looking for a four button Zigbee controller that fits a Decora plate, the AduroSmart ERIA dimmer is compatible with HE. If you’re not bent on the shape, there will be some nice looking Zigbee 3 controllers coming from Xiaomi. Of course we don’t have any idea if drivers will be difficult or easy for them yet, but if they are compliant Zigbee 3.0, they they should be a good buy and reliable.
