Review: 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
Review: 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.
