Sonoff TRVZB - Calibration Lost When Using Valve Opening/Closing Degree Settings

[nicobgr]

Description

The Sonoff TRVZB loses its calibration when the valve_opening_degree and valve_closing_degree parameters are used.

Device: Sonoff TRVZB, OTA 1.4.1 (currently 1.4.4, not yet known whether the issue still persists)

Expected Behavior

The TRV should maintain its calibration settings independently of the valve opening/closing degree configuration.

Actual Behavior

When valve_opening_degree and/or valve_closing_degree are configured and used, the device loses its previously set calibration values over time and doesn't close fully. This requires recalibration each time these parameters are modified.

Steps to Reproduce

• Calibrate the Sonoff TRVZB
• Configure valve_opening_degree and/or valve_closing_degree parameters
• Observe that the calibration is no longer applied correctly
• Need to recalibrate the device

How to trigger a calibration on this device?

Im also experiencing this issue. I using 2 Trvzb, on one this happens almost daily, the valve doesn't close completely, rendering it pretty much useless. On the other device I only observed this 2 or 3 times in the past 12 months.
Didn't find a method to reset it remotely.

I had the same when I set both opening and closing degree entity. Now I set only opening degree entity, closing degree is empty, and valve closing is always at 100 in original thermostat and it works absolutely fine.
