Amazing, small and powerful
Easy to set up, has email capability, using it as a relay input to broadcast alarm. Does much more that just that. Recommend

Exactly what it is
Great product for a very specific purpose, to trigger *other* Shelly relays, but device has no "dry contacts" of its own, just to be clear. Embedded in my wall of my garage, using momentary rocker switches, it makes for the perfect solution to trigger the Shelly relays that control my garage door openers.

Easy Home Assistant Integration for Automation
I used this for a project for Home Assistant to detect fire and smoke from this alarm. It works exactly as expected, super easy with the Shelley App

Uitstekend product, gebruikt voor de besturing van twee lampen in een hotelopstelling. De drie schakeluitgangen zijn geïntegreerd in Home Assistant voor logging doeleinden. Een product van hoge kwaliteit.

Love the versatility of this product. Its not just seen on Alexa as an input as you can configure various 'scenes' and there are a lot of options however there is a Maximum amount under the free account of 3 scenes to trigger Alexa so to create an input option which latches on then off I had to use 2 of my 3 scenes up that said the premium upgrade is only around 35euros for the year which comes with lots of added extras.
