Shelly 1L Gen3

It’s genuinely compact, so it fit behind my existing panel without any wrestling, and the KNXnet/IP handshake was instant once I had the IP set. I’ve been running it for a week now with zero dropped connections, which is more than I can say for my old setup.

The KNXnet/IP integration was flawless on the first attempt, which honestly shocked me for a relay this size. The compact form factor made it easy to tuck behind the wall switch, and the third-gen processing speed feels snappy for instant toggles.

Took a bit of fiddling to get the KNXnet/IP pairing right, but once it clicked, the relay responds instantly every time. The compact size made it easy to tuck into the existing junction box, and I've had zero dropouts in a week of daily use.
