I check the received model

Could not find the reference on the thermometer, it is indicated on the box

I note that in the received model, AAA batteries are not included.

I quickly look at the operating temperatures

It will not go into my freezer, for that I did another Retex, but for the other parts, it is good.

I integrate this box with Zigbee2MQTT

I switch Zigbee2MQTT to pairing mode and add two AAA batteries.

The pairing starts…

It is recognised as a TS0201 and the battery does not seem to go up, it is rather approximate as an integration.

I'm going to Home Assistant.

I can find my equipment there

I'm still checking that the battery information doesn't go back up. On the other hand, the temperature and humidity are good.

The battery problem is not particularly troublesome because on the majority of products in this range, the battery has 100% constantly, so we can't rely on this information.
