SONOFF SNZB-02D temperature and humidity sensor with LCD

Quick verdict

SONOFF's SNZB-02D adds a useful LCD to a low-cost Zigbee temperature and humidity sensor, so you get instant at-a-glance readings plus local automation data. It is a practical pick for climate balancing, dehumidifier triggers, and room comfort monitoring in Home Assistant.

Standout: Integrated LCD with local Zigbee telemetry for both visible and automated climate monitoring.

Local control facts

Home Assistant: zha integration, Local Polling (home-assistant.io, checked Oct 10, 2026)
Zigbee2MQTT: supported device, listed as SONOFF SNZB-02D (Temperature and humidity sensor with screen) (zigbee2mqtt.io, checked Oct 10, 2026)

Why it stands out

built-in LCD display shows temperature and humidity at a glance
excellent zigbee2mqtt and ZHA support - fully local
very affordable for the feature set

Reasons to hesitate

requires a Zigbee coordinator - no standalone use
no native voice assistant support without Home Assistant bridging

Best for

Home Assistant users wanting cheap, reliable temp/humidity monitoring
Zigbee mesh networks needing environmental sensors with displays

Avoid if

you do not have a Zigbee coordinator
you want direct Alexa or Google Home pairing without a hub

Privacy and local-control notes

The sensor works fully locally through Zigbee coordinators such as ZHA or Zigbee2MQTT. Temperature and humidity history can remain on your own Home Assistant instance.

Home Assistant support: supported · integration path: zigbee2mqtt / ZHA.
