I have been using 2 sonoff motion sensors with no issues. Based on my experience over a month with no issues, I ordered more and just last week received a dozen more! I got from aliexpress to my Canada address. I am using one in my bathroom, and other in kids playroom to trigger lights.
They default driver worked great but then I also discovered the user driver which is giving few additional features, so I switched to that driver and things have been working fine - [RELEASE] Sonoff Zigbee Button, Motion/Temperature&Humidity/Contact Sensor Drivers - Developers / Code Share - Hubitat
