Consistency test of the SONOFF SNZB-02 temperature and humidity sensor

Maybe it’s time to give some back to the community. I ordered twelve SONOFF SNZB-02 temperature and humidity sensors and would like to know how consistent or accurate they are. So I put them together in the master bedroom and let them sit for a while. The experiment result turned out quite good. All four sensors are close to each other within 0.3 °C, or 5% in terms of humidity.

I’m working on a complicated project that automates the window/AC/ventilation/sunshade depending on the weather forecast and my personal weather station. It will also include a self-trained Tensorflow model working with Google Coral TPU(as you can see I order two) as room occupancy sensor for better multi zone temperature control.
Will share once it’s functioning. Stay tuned :grinning_face_with_smiling_eyes:.

I was thinking of doing something similar with my 8 Xiaomi sensors and a couple otger calibrated sensors (I don’t remember tge exact brand).
What I noticed during normal usage is that any air movement could influence the readings.
So I was thinking of using a drawer, as far away from any heat sources, preferably in a room with the windows covered.

Hey, did you finish this project? :slight_smile:
