does not work in Europe sever only when connected to China server
Works very well. You can program 3 commands on each button. So altogether 18 command on this wireless switch! I already got three Opple switches and will buy more. The only downside is that you can only add one Opple switch to Apple HomeKit (if you add it to gateway that support HomeKit). You can add several Opple switch to Mi Home but, only one to HomeKit. May be this will be possible after future firmware upgrade.
