Does anyone have the Curv radiator valves working with HA? Is there an integration?
I see on the box it says they are powered by Tuya but I can’t find anything at all about Curv itself.
Any help greatly appreciated.

Have you managed anything yet? I got a couple at an auction very cheaply and was hoping to connect them but so far with a quick try nothing’s worked. I don’t have their gateway and I don’t want it!
I wonder if it might be possible to flash them with ESPhome?
No, I thought they might be ZigBee but the Curv branded TRVs look all to be 868MHz so next to no chance of integrating them without relying on the controller.
Aha. I just found some manuals online that say the same. Shame.
I might try and take one apart and see if I can work out what chipset it uses in the unlikely event it can be flashed with something useful!
Do you have RTL433? I wonder if it transmits anything readable on 868mhz. Problem then is there is no ability to transmit any instructions to it.
I don’t have RTL433. I had a look and when I saw the price of a dongle I thought better of it! 
Any idea how to open them up? Just wondering if it might be possible to flash them with ESP32 or something similar.
I have managed to get the curve thermostats working with the tuya app with the they show app in home assistant.
Are you using the Curv hub or have you got HA communicating directly with the TRVs?
