Hello after installing the new update 1.4.4 on TRVZB an 3.0.0 on ZBBridge-P I have tested the new feature Adaptive mode on 3 TRVZB(a480101f1b, a48010154f, a4801072a9). Unfortunately my experience is not good. After reaching the target temperature all thermostats closed and the temperature dropped with 1 degree and did not turned on(opened) the thermostat…I tried 2-3 times to reset the thermostat settings, but the same thing happened—the target temperature was reached and then the thermostat shut off, even though it showed that it was in heating mode.
I did all this in automatic mode on the thermostats.
Is it an error in the algorithm or am I doing something wrong? Please help.
Same setup here but the opposite problem. My valves dont close when the set temperature is reached and the radiators keep heating full blast until I stop them. SONOFF support not come up with anything yet. Bug in the latest firmware release? Its only been on release for a week so might be a while before SONOFF can fix. They all shut down for 2 weeks for the Chinese New Year in a few days so dont hold your breath.

After a week of trying out Adaptive mode, I came to the conclusion that the model does not self-learn. Therefore, I had to create two automations to restart the mode (turn off Auto, wait 1 minute, and turn it back on at a temperature of ± 0.4 degrees). This reverses the action of the heating mode. Otherwise, the good thing is that the temperature changes more smoothly at the end point.
I reported this overshoot to SONOFF support. This is their reply:
After checking with the technical team, under the current adaptive algorithm, the valve opening degree will gradually decrease once the target temperature is reached and will fully close when the temperature exceeds the target by 2°C. If you find it too warm, it’s recommended to set a calibration of -1 or -2°C.
I’ve reverted to using the Vesatile Thermostat add-on which controls the SONOFF valve adequately.
