### ⭐⭐⭐⭐⭐ Great Relay!
*by D***6 on April 7, 2026*

Researched lots of pool pump time clocks and didn't want to spend that much money on them. Found these Shelly relays and love them! Recently got into smart home integration and was very happy with how easy it was to get the relay included on my home assistant instance and programming the automations was pretty easy after a few youtube videos.
