kravemir, Nous E6 is currently my most favorite Zigbee temperature and humidity sensor.
I love it works with rechargeable 2xAAA NiMH batteries, and seems to last quite long (battery life testing in progress).
Works nicely in HomeAssistant via Zigbee2MQTT.
I wrote a bit more details about it in https://kravemir.org/product-reviews/nous-e6.
What's yours the most favorite Zigbee temperature sensor, which works with rechargeable AA/AAA batteries?
