So over the last couple of days I have been setting some new Aqara products up in my new house. For a long time I have been using the T1 Temp and Humidity sensors on my wine cooling cabinets to monitor humidity and temperature which has been working perfectly…. A few days ago I then bought the new W100 and for testing put that in next to one of my T1 sensors. One would expect they would come out pretty close to each other both temp and humidity wise, but that is certainly not the case
The T1 gives temp 12C and 75% humidity
W100 gives temp 13C and 64% humidity
In my line of business (approx 1mill USD worth of wine) the difference between the 2 units are significant. (And yes the W100 has been in the same place for +24 hrs to remove any area for faulty measurements).
So what’s your thought on this and have others done same comparisons?
Hello. I think that W100 has more accuracy, but do not forget that this device is not calibrated and not verified by the metrological service (also T1). If you need to know the temperature very accurately, you will have to install a calibrated thermometer (mercury or other) and perform calibration with fixing the temperature error.
Comparing the temperature of W100 with T1 is incorrect. In T1, the temperature sampling is much smaller compared (T1 takes measurements once an hour or when the temperature changes by 0.5 degrees) to W100. Use my description of W100 settings, make a detailed analysis using the graph in the Aqara Home application.
That T1 takes measurements once or he is factual wrong. It takes measurement every 5-6 min. (See attached) where as W100 does it very randomly looking at the logs… the picture with both temp, humidity and pressure is from the T1 where the humidity is from the W100 log…
To understand the algorithm, your T1 gives the temperature only because the humidity measured by the sensor changes and therefore sends an information signal that includes temperature data.
