Sonoff SNZB-02UL AirGuard E-Ink TH: Capabilities And Limitations
Based on listed specifications, not hands-on testing. Manufacturer sources are linked where checked.
What it offers
Temperature alerts are recorded as an automation or notification option. Check configurable thresholds, notification routes and any hub requirement. A custom comfort range, one of six presets or edited by hand, pushes a phone notification when the reading leaves the band.
View Temperature Alerts details →A screen is listed, providing an on-device interface to investigate. Check which readings or controls are available on the device without opening an app. 2.9 inch flexible dot-matrix E-Ink panel with a nearly 180 degree viewing angle, readable in bright light. Without a gateway it shows temperature and humidity plus the past 6 hours on a button press.
View Screen details →A Home Assistant integration is listed, providing an integration path to verify for the exact model. Check the exact integration and firmware. A catalog integration label does not establish local control, official support or available entities. Zigbee2MQTT works out of the box, while ZHA needs the script SONOFF publishes in its help center for the advanced functions such as the remote sensor display and the weather data.

What to consider
Touchscreen input is listed as unavailable; check the other control methods. A single button on the back handles the 6-hour history recall, the temperature unit switch and pairing.
