I just got some Sonoff S40 Lite plugs and I am trying to pair them with Home Assistant via ZHA. The device is found and I get the “Starting Interview” box, but that is as far as it goes.
I am running HA on a RPi with a Sonoff Dongle-P. The dongle is approximately 6 feet away from the Raspberry Pi on a USB extension cable. I have six other Zigbee devices and none of them are having issues.
Thanks for the info. So, it could very well be the S40! When I ordered them I got the S40s over the S31s because they were a little cheaper. I guess I know why now. I think I am going to return these and try the S31s.
I bought a dozen of the S40 Lite plugs because I, too, thought I was saving money.
I tried 2 and had the same issue with both. Glad to see that you posted the thread, as I thought I might be doing something wrong. It looks like it should be supported, I’ll submit a report. SONOFF S40ZBTPB control via MQTT | Zigbee2MQTT
