2PM Gen3 | WiFi 2-Channel Smart Relay Switch with Power Metering | Home Automation | Roller Shutters, Blinds, Gates Control | Remote Control | Alexa & Google Home | iOS Android App

Shelly's thoroughness in engineering and design really shine thru with these things. I rewired 6 ceiling fans in my house using these to control the fan and light independently. No problems, and seamless integration with Home Assistant. Absolutely love Shelly products in general.

Perfect size, compatible with google home, easy to install and connect.

In the weeks that I've been using it, the Shelly 2PM Gen 3 has proven to be remarkably dependable. It was easy to set up, connected to Wi-Fi without any issues, and integrated seamlessly with my Home Assistant setup. The surprisingly accurate power-metering feature allows me to see the energy usage for each channel in real time. When I use mine to control two separate circuits, the independent relay control works perfectly. The connection has never been lost, and the web interface and the app are both responsive. Anyone putting energy monitoring or smart home automation into practice will find this to be a reliable and flexible solution that just works.

I rebuilt a 2 stage, 8-lamp fluorescent grow light fixture with transformer bypass LED lamps. I wanted to be able to control each stage using predefined routines via wireless control. The Shelly was small enough to fit totally inside the fixture and it works flawlessly.

These are great for home automation and the app is really good too.

great product, well engineered device and ecosystem. Easy to setup and use... only I bought 13 (one spare) and two failed almost immediately (weeping face). This is why a 4 not a 5. They are replaced and serving the goal well. The goal was to automatically close emergency shutters in the event of tornado or hurricane. The only part not done and fully automatic is integration of Alexa to the Emergency Alery System (which has nothing to do with this product).

Blown away by how good the firmware on these things is compared to everything else I've ever used (Tasmota, ESPHome, not to mention tons of no-name Chinese parts). Plug and play, don't need an app, immediately integrates with HomeAssistant, can act as a smart switch, and it's way way smaller than I expected. Just an amazing package, will be buying more!

It's works flawlessly. I love it. Once programmed, it works without being attached to wifi. And I think you could program it via Bluetooth too.
