Some more nice Alexa news today.
Facebook user Иво Игнатов did notice that the Alexa app now supports Zigbee motion sensors as trigger for Alexa routines:
Hi Group!
Did anyone notice that Sonoff zigbee motion sensor is now able to trigger routines in Alexa app? I’m already enjoying this feature. It opens so much possibilities. 🙂

Perhaps more kind of motion sensors register at the eWeLink app are supported.
