European Heating (TRV) support options?

Possibly just the valve itself.

I don't think so. The valve works perfectly with the Spirit TRV and the mecanical TRV.

Fair enough. I would say that the actuator on the Shelly might not push the pin fully in on your valve but if it only happens sometimes that would be unusual.

Flawless.

Reliably setting various trv set points

Just an update - works to perfection. The wife is actually beaming. Previously she hated it, but liked the cost savings. Edit. Pics. Inside that double back box, there's a nodemcu connected to a 3v relay controlling when the ac power is able to flow to the thermal actuator. All looks quite slick, to be honest. Also purchased a few momentary buttons. Plan is to have a button on the box to activate a 20 min boost, which is currently only done via software. A light too to show when the valve is ac…

not push the pin fully

Yes, I tried to place a small piece of plastic between the pin and the head of the Shelly, but then it shows an error. I also have set the extra force on and calibrated multiple times. It seems to work perfectly for hours, but then at some point the valve stays open. The weird thing is that, even setting heating to off, does not close it. It happens from time to time (once a month) that a spirit gets stuck (mainly the newer ones) but after taking out a battery and restarting it, it works again. This isn't an option for the Shelly, and the Shelly gets stuck after hours.

Have you talked to the shelly people about this???
