How do you deal with grounding? None of them seem to have ground pins which is rather concerning
May I ask why grounding is concerning? Im not expert, but afaik normal wall switches dont use ground wire and ceiling lights may use one. I thought if wall switch is made of plastic there is no need for grounding. Please correct me if Im wrong, I want to learn. I was looking at sonoff zbmini-l2, but didnt buy any yet
Every normal electrical box in every house ive lived in has a white wire, a black wire, and an exposed copper wire. Every switch has always had a green screw that the copper wire goes around. The zigbee adapters all seem to lack a spot for the copper wire, which is meant to help protect electrical equipment and prevent fires during events like power surges and whatnot.
@semperverus
In European countries you only have live wire, never the ground, neutral in newer installations.
The switches don’t need ground as there is no exposed metallic component. Ground is needed where a human could be exposed to live (due to a fault) as it would trigger the breaker.
