The All-New Sonoff E-Ink Zigbee Temperature Humidity Sensor

Sonoff SNZB-02UL

A quick blog to go along with the video I’ve made on the new Sonoff SNZB-02UL sensor – released September 24, 2026. As I’ll be on the road, here it is a few hours early (depending where you live of course).

Please watch the video which gives you an overview of this brand new e-Ink device as installed in Zigbee2MQTT without any external proprietary apps. I’ve explained and shown the features that appear in Zigbee2MQTT and I expect they’ll be more or less the same in Home Assistant (HA). When you’re done with the video – look here…

Right now, not quite so much directly in HA as in Zigbee2MQTT (which of course is available in HA anyway) but here are the sensors, configuration and diagnostic panels that appear in HA.
