Shelly 1 Mini Gen4 2-pack

I was worried the relay would be bulky, but the mini footprint fit perfectly behind my light switch. Bluetooth setup worked in about two minutes, and the WiFi connection has been rock-solid since. For two units at this price, it's a steal.

The WiFi setup took me under five minutes per unit, and the Bluetooth fallback is a nice safety net if my network ever hiccups. These little relays are barely bigger than a matchbox, which made squeezing them behind my light switches way easier than I expected.

Flipping these two relays into my existing light switches took less than an hour, and the WiFi connection held steady through a full weekend of toggling. The dual connectivity is a nice safety net too—when my router blinked, Bluetooth kept the schedule running without a hiccup.
