Hi. I'm currently using TRV06devices which are working ok, but there a few downsides:
- They are not charged by usb-c, instead the batteries need to be replaced. I would love to have devices that can be recharged via usb-c while they continue to work (i would charge them via powerbank 1-2 times a year).
- The battery charge-level is not to be seen anywhere. On the (hardware-)device they are just showing a symbol if the battery is really low, but i would love to have that in HA.
- My apartment (living in Germany) has somewhat older radiators and I have the feeling that the devices are not as tight/correct fitting as they should. Especially in one room the thermostat fell off frequently because it was getting loose over time (also I think because when the radiator heated up and cooled off, there was a big difference in tightness due to the heat-expansion). I would love devices that are really high-quality grade in a way that they fit very tight and durable.
Previously I was going for cheap valves but now I would be ok to spend more money IF they can be recommended 🙂
