Russound CAx6.6

CAx6.6 for Homey (Pro 2023) Because your multiroom audio deserves fewer remotes and less guesswork. This app controls compatible Russound CA-series amplifiers via ASCII RS-232 over TCP using a serial-to-network gateway (MOXA NPort, ser2net, or similar). It creates one Controller device and six Zone devices automatically. Features - Turn zones on/off - Set volume (0–100) and mute - Select source (1–6) - Use it in Flows without memorizing serial commands - "All zones off" action on the Controller device Requirements - Russound CA-series with ASCII RS-232 protocol enabled - RS-232 to TCP gateway (TCP server mode recommended) - Serial settings: 9600 8N1, no flow control - Correct RS-232 cabling (TX/RX/GND, and if needed a null-modem adapter depending on your setup) Compatibility / IMPORTANT ⚠️ Some Russound CAM6.6 units are hardware-locked to the RNET protocol (binary) and will NOT work with this app. If you see unreadable binary data (“gibberish”) in your terminal when monitoring the RS-232 port, your unit is using RNET. Quick test 1) Connect to the gateway: nc <gateway-ip> <port> 2) Send: !Z01ON<ENTER> If the zone turns on, your unit likely supports ASCII control. If nothing happens and you only see binary output when using the remote/keypads, your unit is RNET-only. Notes - This is not an official Russound product. - The app may use "optimistic state" for some settings (it assumes the last command was applied).
