Anyone in Australia, as an electrician, the best option is Clipsal Wiser switches, dimmers, relays etc.

Zigbee that defaults to standard push button operation when the network drops out.

If using HA you DO NOT need to purchase the hub that they say is required to use the switches.

Are we the same person? I’ve had my Regulus, skeletool CX and mini skeletool (top left forgot name) for years and years.
