Brilliant little device
I managed to get myself locked out of my camper a couple of weeks ago with both sets of keys inside. This little board arrived this morning, and within half an hour it was set up and connected to Alexa using voice controls to operate the relays. Next step is to connect it to the central locking so that if I get locked out again I can ask Alexa to let me in (using obscure phrases nobody would ever guess). Works of 5v micro-USB connection, or 7-40v, so can be connected to vehicle battery without needing an external regulator.

Uses its own app but works with alexa

Works great, wire terminals seem fragile so recommend holding them when screwing in.
Used to automated 12v fans in and old bunker. Controlled via an esp32.

Works with Home Assistant
You can use the app to connect and set up, then add the integration to Home Assistant to control via there. It does use 2.4g WiFi rather than the Zigbee HA controllers own mesh network. So if your router goes down it work work...but that's unlikely right. The dashboard integration doesn't update automatically so you have to refresh manually... But most use cases won't use the dashboard anyway. If you have logic set up and need a 2.4g wifi switch controlled via Home Assistant... This will work OK.

Works perfectly
Using this device as a momentary switch to open electric gates remotely. Absolutely perfect. Setup is so easy and install can be done with basic know how of electronic relays. 100% recommend.

Works flawlessly Alexa
I set this up to control (open/close) two separate garage doors via Alexa. Setup was fairly easy and fast. It has numerous settings available once you set it up in the Ewelink App. I wired it directly to my existing opener wall mounted push buttons. After installing and creating routines in Alexa it works flawlessly.

Au top!
Boîtier de commande au top pour commander des moteurs de tracker pour panneaux photovoltaïques. Pour ma part, Il actionne les moteurs du lever du soleil à son coucher afin d’avoir une inclinaison optimale pour la production d’énergie. Et surtout, je peux les remettre à plat en cas de fort vent et tout cela à distance!
