Good

AZDecember 4, 2025

I love sonoff products, except zigbee. They work flawlessly as much as software can. This plug no exception. It's simple and i never saw it glitch unlike 4ch pro or basic. My basics sometimes forget to turn on or off on schedule. The 4ch had a stuck schedule entry which i couldn't see in the app, but removing and adding all schedules fixed it. The plug - no issues. Wifi always reconnects if it loses connection due to environmental factors (trees, weather). The energy monitoring sucks though. You do see an accurate chart but instantaneous value shows zero for me. I run a motor (pump) on it and like to be able to see activity. I just use the chart. Maybe I'm doing something wrong, as the pump comes on and off and i may be catching it at the off time. But i remember that something didn't look right. Read more
