Describe the bug

Since last update my SONOFF trzvb receive the following configuration when heating is off:

• Opening degree: 0
• Closing degree: 99

I have 10 TRZVB at home and on at least 2 of them (not all) this configuration allows water to flow in the radiator, heating empty rooms.

I saw a recent update that might have induced this behavior, currently in my setup it seems that unless closing degree reaches 100% my radiators aren't closed.

I don't see parameters that would allow me to bypass this feature.

In the following example temperature increased by 3 degrees although temperature requirements were lower:

Hello, with an opening degree at 0, it should not heat. Definitively.

Yes there has been a improvement for a workaround to the hvac_action issue last week. See release note.
