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
