Description

Too hot, too humid, degraded air quality: indoor comfort issues often go unnoticed due to a lack of reliable measurement. The SNZB-02P integrates a Swiss-made sensor that measures temperature and humidity with clockwork precision, refreshes every 5 seconds, and operates for 4 years on a single battery.

Key points

🇨🇭 Swiss precision sensor - ±0.2°C

The onboard hygrometric sensor is manufactured in Switzerland, guaranteeing an accuracy of ±0.2°C for temperature and ±2% RH for humidity. Significantly more reliable than generic entry-level sensors.

Refreshes every 5 seconds

Data is updated in near real-time as soon as a variation is detected. Ideal for precisely controlling a thermostatic valve or automatically triggering a VMC.

🔋 4 years of battery life on a single battery

Powered by a CR2477 3V battery. No battery changes for years - the app alerts you when the level gets low.

📊 6-month exportable history

View temperature and humidity curves for the last 6 months from the eWeLink application. Data export available for analysis.

💡 Our recommendation: The SNZB-02P is the reference sensor to pair with the TRVZB thermostatic valve. Place it in the room to be heated, away from the radiator - Home Assistant will use its measurement as a reference probe to control the valve with much greater precision than the valve's internal sensor. For baby rooms, configure an alert if the temperature falls outside the 18-22°C range. If you need a local display without an app, opt for the SNZB-02D instead (same sensor, with LCD screen).
