The Shelly Pro 4CB C32A is a professional-grade device from Shelly Europe, designed for reliable operation. It features both Wi-Fi and Bluetooth connectivity, and is part of the Pro CB line.
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.
