So, when Aqara released their E1 TRV, I noticed that what appeared to be an identical Tuya TRV came out, which I found on AliExpress here:

So… I bought two, and they appear in home assistant as follows:
I’m curious as to how this differs from the Aqara E1, as they appear physically identical, right down to the layout of the icons on the screen.
I’m assuming, all Aqara did was change the firmware to make it compatible with their app, and allow pairing with their external temperature sensors.
And last question, does the E1 have (hardware supported) temperature calibration to adjust for the radiator being right next to it ? In the clone, there is a temperature calibration field in the quirk, but its not supported in the hardware itself, the quirk simply takes this value and knocks it off the reported temperature shown in the UI.
