With the smart hygrometer sensor of Swiss manufacture, the temperature is accurate to ±0.2°C/±0.4°F, while the humidity is ±2%RH, data measurements are updated every 5 seconds to give you the latest changes in temperature and humidity.
Specifications are collected from official manufacturer websites. Please verify the specifications before proceeding with your final purchase. If you notice any problem you can report it here.
I have been using it for 10 days connected to a Sonoff ZB Bridge-P, where in combination with another Sonoff device, it activates an n/c relay that in turn activates or not a central heating system. So far, the SNZB-02P appears to be quite accurate in its measurements. Related images from the eWeLink app.
I got it to have a measurement of the external humidity and temperature for use with openHAB. It shows very good. Other Sonoff models have been working for a year without battery change. This specific model is said to last much longer (4+ years), so it will last without battery change for many, many years. Also, it gives more accurate measurements than the other models. I believe that is the case. This specific one is very close to the Sonoff zigbee USB hub that I have installed on my PC, but other models, theoretically inferior, work just fine even 15m away and with multiple wall interference. I imagine the same will apply to this one. Overall, I have developed a strong preference for the zigbee communication protocol for low-power sensors compared to WiFi.

It looks good but I couldn't try it because it necessarily requires a bridge
