If you are thinking of getting the SNZB-02D for temperature monitoring or room temperature control via Zigbee, then definitely do not buy the SNZB-02D. The problem is that in the current firmware version, the sensor has a temperature reporting resolution over Zigbee (connected to Home Assistant via Zigbee2MQTT) of only 0.2°C. Even if you try to set higher precision in Zigbee2MQTT, in practice you only get 0.2°C, which is useless for regulation or more precise monitoring.
Paradoxically, the manufacturer states this on their website as: "High accuracy – Swiss hygrostat measures temperature and humidity with an accuracy of ±0.2°C/RH" -:(
It reports humidity changes without any issues and immediately upon a change of around 0.1%, but there is a problem with the temperature. So bear that in mind before ordering!
solid mechanical design
display
nice appearance BUT!
temperature resolution of only 0.2°C
unnecessary comfort symbols on the display, but this can be disabled in the settings via Zigbee2mqtt
