Toon OpenTherm CV information

[Arnout2000]

I was just wondering, on the CV statistics tile, I see amongst other data the target water temperature and the real water temperature when leaving the CV.
However, the water temperature IN is always 0.0 Degrees. Is that because my CV does not provide this data or is there another reason for that?

that is because you're CV does not provide this data..
