SONOFF Zigbee 温湿度センサー | SNZB-02P

I’ve been using it in my pantry to monitor humidity for dried fruits, and the ±2%RH accuracy gives me real peace of mind. The data updates every five seconds, so I can see changes almost instantly when I open the door.

The five-second refresh rate is honestly the feature I didn't know I needed—my fermentation chamber stays within 0.1°C of target now. Setup took about two minutes and the readings feel rock-solid compared to my old analog thermometer.

I was skeptical about the ±0.2°C accuracy claim, but after a week of comparing it to my old thermometer, it’s spot on. The Swiss sensor really shows in how consistently it tracks both temp and humidity without drifting.
