So, just got my HA Green. I had it up and running, the YoLink integration, and the detection of my meter and valve all going in about 10 minutes (pretty good since I'm starting with zero HA experience).
But only the valve controller's battery status and water volume reading are picked up with HADB. The valve controller is not an option to choose as an importable device.
Now I see "valve" isn't listed as a supported device ([RELEASE] Home Assistant Device Bridge (HADB)). Oh well, I guess I'll try to go the other way and see if HA can import the water sensors from HE.
Edit: Adding some pictures.
