Review: Smart Laser! - These are cool devices. I used them to monitor outputs from my laser cutter from home assistant. I just hooked each of the laser outputs to the inputs on this relay and can now monitor and track runtime, set up automation easily and basically just nerd-out on home assistant. Shelly offers a solid product!
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.

### ⭐⭐⭐⭐⭐ 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
*by T***S on September 6, 2025*

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
