Hi everyone, I’ve managed to download the new firmware. It seems to be working well. The regulation is stable with only a minor temperature deviation, which can be fine-tuned using the temperature offset (compensation) settings. The smart schedule is running smoothly without any drops. Great job by the Aqara team!
I haven’t tested yet how the valve will work with the W100 sensor, as it kept disconnecting and overwriting the sampling rates last time. I’ll see. So far, so good.
“I would also add that it would be awesome if the app showed the valve opening percentage and a window icon whenever the ‘open window’ detection is activated.”
Hi, the PID system is self-learning. Therefore, it (theoretically) should be self-correcting. You enter the starting correction, as I said, depending on the peculiarities of the radiator placement.
Not sure I understand why that should be necessary, or why it is a fix. The measured current temperature reported by the trv is accurate, but never the target temperature.
I would expect the difference between the two to differ depending on heat loss of the room, which will depend on outside temperature. So it seems, as the outside temperature rises as we enter spring, I would have to adjust the offset to reach my desired target temperature.
What exactly do you mean with “self-learning”? Something like adaptive controller parameters? That would be super interesting. Do you have more information on that?
I might be repeating myself, but the offset (that can be set in the app) has nothing to do with the performance of the controller.
Its purpose is to make the temperature measured by the thermostat (i. e. close to the radiator) match the temperature measured by an external thermometer in the middle of the room.
You shouldn’t have to fiddle with the offset to make the controller work!
If the thermostat controller is not able to reliably hold the temperature at the target, changing the offset will not fix it.
So you are right: If the reported temperature is accurate but not the target temperature, this is not a problem with the offset that can be set in the app.
Hello, @Tech-savvy, can you give us an answer.
PID mode when using an external sensor W100 uses the internal temperature sensor.
This question is important for us so that we (users) understand what affects the target temperature in the room.
We will understand how to use the “compensation” parameter.
Thanks for the answer
I have created the ticket to whitelist me for a new fw, support confirmed I am added, I have enable Beta fw in the app, but still showing only fw 1839. What else can I do? I would really like the new fw, because now we have cold or too hot in bedrooms
Same problem here: I have enabled “Beta Firmware” in the Aqara Home app, i have created a ticket and sent a private message to @XianTangHE. But i still don’t receive the new firmware versions and i am stuck on FW 1839, which is completely broken.
Meanwhile I got an update to Thread firmware 1.0.0.8 and while there don’t seem to be any oscillations any more, the controller behaviour is still far from perfect.
Today I noticed that one of my W600s was reporting a valve position of 19.2%, but the radiator was completely cold. Calibration did not help. The same result after calibration.
