I check the received model

 

I quickly look at the operating temperatures

• Working humidity: 5-95 % HR (non-condensing)
• Working temperature: -9,9 to 60 °C

🛒 Where to buy this equipment?

Here is the link to the page dedicated to SNZB-02D. I referenced the sellers and prices.

I integrate this box with Zigbee2MQTT

I switch Zigbee2MQTT to pairing mode and remove the tab to connect the battery.

 

When connecting the batteries, the temperature and humidity are displayed on the screen, they are fair.

The pairing starts…

 

 

It is perfectly paired.

 

I'm going to Home Assistant.

I can find my equipment there

 

It is perfectly integrated!
