Fits perfectly inside a standard junction box, which surprised me given how compact it is. The 8A rating handled my hallway lights without any heat issues, and it connected to my Wi-Fi in under two minutes. Setup took maybe ten minutes total and it's been rock solid for two weeks now.
Installed this behind my gate motor and set up a schedule in under ten minutes — the compact size made wiring a breeze even in the cramped housing. It's handled the 8A load without a hiccup for three weeks now, and the Wi-Fi connection has been rock solid.
