MC3100ZB (MultiController) wrong internal temperature readings
Closed this issue · 5 comments
Hi, first of all, thank you very much @claudegel for all the work you've done to integrate sinope's devices to HA. I use your work a lot as I prefer encouraging a local brand and I am an opensource enthousiast.
I am posting this here but I am not yet sure if this is a hardware problem with my device, I am starting to investigate the issue here but I could also contact Sinope as the temperature reading never worked (the device is quite new).
So, the problem I have is that the temperature reading of my device is always a bit off. Actually about 1 degree lower in the 20-25 C range, it gets worse when then temperatures are lower, and I can notice no difference at around 28C.
At first sight, it looks like the internal sensor is mis-calibrated, or just bad. I started looking into the quirks here to see if there would be a way to calibrate the internal sensor. In the meantime, I conntected a 10K sensor to the "external" sensor (it's actually inside the device anyway), as this one seem acurate.
Would you have any clue on what could be wrong? BTW I also connected the device to neviweb GT130 and it does the same, tho I connected it to ZHA first. It's totally possible it's a hardware issue like I said.
Here's the comparison I did last night: You see internal vs. external 10k sensort vs. 3rd party temperature sensor with a very bad refresh rate.
My question is: I am not familair with ZHA quirks, do you think it could be a way to calibrate the sensor from a quirks? Otherwise I guess I workaround the issue by writing an automation that produces the "fixed" values from the offsetted values?
I'm also curious to see if others have similar issues?
Hi in ZHA there is a slider for temperature offset, If your temperature is always off by about the same amount of temperature you can adjust it there. It is possible that your temperature sensor is defective. Could be good to call Sinopé. In Neviweb130 there is no way to adjust the sensor temperature.
Sorry your device is a MC3100ZB or a Thermostat? the above adjustment is for thermostat
TThe internal sensor is for the device temperature, not for room temperature. This is why there is aanother connection for an external sensor. I'm using this one with a floor sensor which is installed ooutside to get outside temperature and send that back to all my thermostats. I've talked to Sinopé wwhen I got mine because I noticed that there was a slight difference with the room temperature and tthey told me that it was the device temperature and not the room temperature.
There is also temperature sensor in the light switch and dimmer to monitor device temperature. This is available in ZHa. I think that there is internal temperature sensor in all sinopé devices. I was able to detect a light switch that was very hot because of excessive insulation and there was many device in the same wall box.
OK thanks for the clarification, so my "workaround" is now my final solution! I was hoping to get both outdoor and indoor temperature with a single device, but I'll live with only indoor and use accuweather for outdoor.
