Shelly Pro 4CB C32A

Setup took me about ten minutes and the Wi-Fi connection held rock solid through the entire install. The Bluetooth fallback is a nice backup if I ever need to reconfigure it without touching the network. Exactly what I needed for a clean, reliable install.

The dual connectivity is a lifesaver—Wi-Fi for the main setup and Bluetooth as a backup when my network hiccups. I’ve had it running for two weeks now and it hasn’t dropped a single command. Solid little module for the price.

Installing this in my panel was straightforward, and the DIN rail mount clicked in securely. I was surprised how stable the Wi-Fi connection stayed even with the metal enclosure closed, and so far it hasn't dropped once.
