Very good board, it's great to be able to use dry contacts, instead of live contacts on Sonnoff. I use it to control wood pellet burner. Powered it through usb and it connected via eWelink app in seconds! Tried to power it with 5V through the on-board screw terminal but it won't connect. Also, the reception is better than of Sonnoff basic. On the same location, this board works without any problems, and Sonnoff couldn't connect even with an external wire antenna added.

Love these units. I have purchase two of them. Use 1 to make momentary contact on Somfy remote so I use alexa to raise and lower the patio Bali/Sunsetter shades. other used to turn on a traffic light and change the light functions via app and Alexa. The're Great!

Nice switch, full of features. I installed it on a garage door so I can have the door open by the time I arrive home. Easy installation, quick and easy app setup. I can also use 433mhz remote that can be programmed. Great!
