Product Information

D) SONOFF seems to be targeting retrofit applications, so I think they’re assuming you will just use your existing NM cable for the signal wire. But I’ll be using these in new construction, so 12-guage wire seems like overkill (I’m assuming the signal line is 5V or 12V). Is it safe to use 18-guage wire (like for low-voltage lighting) for the signal line? And would using it pass US electrical codes?

Service switch can break easily, probably due to the casing that is part of it, to be handled with careSo if I walk upstairs and hit the switch at the top of the stairs, what does the unit do? Does it recognize the change in state to the signal line and turn the light off? Or does it recognize the switch signal is now in the on (closed) position and leave the light on? If the latter, do I have to flip the switch on and then off again to turn the light off? Derudover kan ZBMini-L2 tilføjes til Home Assistant ved hjælp af ZHA og Zigbee2mqtt for lokal kontrol og OTA af enheden. ZBMINI-L2 versionen er produktversionen af relæet, der ikke kræver en nul-leder, og fungerer kun med fase (live) ledningen. Out of the box ZBMINIL2 is already in pairing mode. If you need to re-pair, hold the device button for 5 seconds until the green LED slowly blinks. Enable Zigbee2MQTT debug logging and Zigbee-herdsman debug logging and provide debug logs https://www.zigbee2mqtt.io/guide/usage/debug.html The wiring diagrams above show how to connect the ZBMINI Extreme to a two types of switches and a load. The switch only needs the L line and S1 and/or S2 port to connect to an external switch. It would then work in two ways: from the physical switch and from the application. You can also wire a 2-way physical switch control. For those who have experience with the SONOFF Basic, this is different as the Basic model doesn’t have a port to connect an external switch, and it only enables control from the application or tiny button on the device that is not convenient to access.

You can flash these with ZHA if enable OTA and then manually copy the OTA file(s) to correct directory: Sonoff ZBMiniL2 doesn’t have a power meter function, not a massive issue as the switch will be connected to a source with fixed power consumption. You can get estimated consumption using my flow in NodeRED. The device alone has a minimal power consumption of its own.Sonoff ZBMINIL2 is a successor to the ZBMINI and ZBMINI-L in-wall relay modules. It takes the best of those two and combines them into the smallest smart relay module I ever saw. And it doesn’t even need neutral wire to run!
