I came across this thread while working on my own setup and wanted to share that I’ve published a custom Home Assistant integration for U by Moen smart faucets (MotionSense / Smart Water Network models).
The integration is cloud-based (polling Moen’s API) and unofficial, but it exposes the faucet as Home Assistant entities and services, including valve control, flow rate, temperature presets, volume dispensing, and sensors.

Happy to answer questions or test additional faucet models if anyone’s interested.
