Valve is not closing sudenly!

[barat]

Today I'm experiencing weird behavior. Even if the room temperature is way over set limit valve remains open. I hear it, radiator is hot (because other places are heated so water flows) but App states that this valve is not heating.
What's more "funny" is that when I hit "calibrate" I hear that valve is closed for a while (I hear the water flow stops) so radiator is fine - only Valve remains open even that it should be closed.
Anyone else such problems?

Same for me. One out of seven valves remain open.

I have had the same experience in the past. Deconnecting and reconnect the valve and recalibrate was the solotion for me.
