Description

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.

Sonoff SNZB-02P

The SONOFF SNZB-02P is an advanced temperature and humidity sensor, designed to provide accurate measurements and instant updates about your home environment. Equipped with a high-precision Swiss-made hygrometer, it offers ±0.2°C accuracy for temperature and ±2% for humidity, updating data every 5 seconds for near real-time monitoring.

Compatibility with Zigbee protocol

Compatibility with the Zigbee 3.0 protocol allows easy connection with many gateways, such as SONOFF iHost, NSPanel Pro, ZB Bridge Pro, ZBDongle-E, as well as third-party Zigbee 3.0 gateways like Echo 4th generation and SmartThings Hub V3. This wide compatibility ensures smooth integration into your smart home system.

Sends instant notifications to your mobile

The SNZB-02P instantly sends notifications to your mobile phone when the temperature or humidity exceeds the preset comfort limits, helping you maintain a healthy and comfortable living environment. This allows for quick response to extreme conditions and the automation of smart scenes, such as activating fans or humidifiers according to the needs of the space.

    I use it via Zigbee in ZHA on Home Assistant and the stability is exemplary. Pairing is easy and it maintains a solid connection.

    I have placed it on a balcony, in a protected but outdoor spot. The temperature and humidity readings are very close to reference values I have compared. I have not seen any deviations or spikes. For automations, climate monitoring, and dashboards it is ideal.

    Battery consumption seems low and the reporting interval is properly set so as not to "flood" the network with unnecessary traffic.

    Here too, the store was prompt in shipping, with careful packaging and proper updates.

    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
