Zigbee Temperature Humidity Sensor with LCD Display (Tuya)
Read temperature and humidity locally on the built-in LCD, and push that data over Zigbee 3.0 mesh to Home Assistant, Hubitat, or any Zigbee2MQTT setup. No cloud required. No app required. Just data, where you need it.
Pairs with ConBee II, SkyConnect, and CC2652-based coordinators out of the box. Zigbee2MQTT exposes it as a standard MQTT device, so you can pipe readings into Node-RED, InfluxDB, or any automation stack you already run. At $9.99 and 6 to 12 months on a battery, it's the cheapest sensor node you'll deploy.
Things to build with this
- Use Zigbee2MQTT to push humidity readings directly into a Node-RED flow that triggers a GPIO relay on a Sonoff Zigbee dongle, cutting power to a dehumidifier the moment RH crosses 65%
- Log temperature data from multiple units into InfluxDB via MQTT and build a Grafana heatmap showing thermal gradients across rooms, useful for diagnosing HVAC dead zones or insulation failures
- Set up a Home Assistant automation that cross-references this sensor's humidity spikes with your bathroom exhaust fan's Zigbee smart switch, using the 10-minute reporting cadence to calculate average moisture clearance time after showers
Key Features
- Zigbee 3.0 mesh: pairs with ConBee II, SkyConnect, CC2652 sticks, and most Zigbee 3.0 coordinators
- Built-in LCD: current temp and humidity visible without opening any app or dashboard
- Temperature accuracy ±0.3°C, humidity accuracy ±3% RH
- Battery powered: 6 to 12 months runtime at 10-minute reporting intervals
- Zigbee2MQTT compatible: exposes as a standard MQTT entity for Node-RED, InfluxDB, or custom scripts
- Works with Home Assistant, Hubitat, and SmartThings natively
- Local-only operation: no cloud dependency when used with a local Zigbee coordinator
Frequently Asked Questions
Does this work with Home Assistant without Tuya or a cloud account?
Yes. Pair it with a local Zigbee coordinator (ConBee II, SkyConnect, CC2652-based stick) and integrate via ZHA or Zigbee2MQTT. No Tuya account, no cloud, no API keys needed.
What battery does it use and can I adjust the reporting interval?
It runs on a CR2450 coin cell. Reporting interval depends on your coordinator and firmware. Zigbee2MQTT exposes configuration options for some Tuya devices, but 10-minute intervals are the typical default and the basis for the 6 to 12 month battery estimate.
Will it act as a Zigbee router and extend my mesh?
No. Battery-powered Zigbee devices are end devices, not routers. They do not extend the mesh. You need mains-powered Zigbee devices (bulbs, plugs, repeaters) to extend range.
How accurate is it compared to a dedicated sensor like an SHT31?
The listed specs are ±0.3°C and ±3% RH, which is respectable for this price tier. It uses a sensor in the same class as common consumer modules. For lab-grade accuracy, you would need a calibrated reference sensor. For home automation and HVAC triggering, this is plenty precise.
Why we stock this
Curated by Kindly Morrow. We test and vet every product before it hits the store. If we wouldn't use it in our own builds, we don't sell it.
Things to build with this
Fun projects to try once you get your hands on it.
Movie mode with one tap
NFC tag on your coffee table. Tap your phone: lights dim, TV turns on, blinds close. Tap again to undo. Feels like magic every time.
Laundry notification system
Vibration sensor on your washing machine. When it stops vibrating, your phone buzzes. No more forgetting wet clothes for 3 days.
Automatic night light path
Motion sensors in the hallway trigger dim warm lights at floor level after 10pm. Walk to the bathroom without waking up fully.
Mailbox alert
Contact sensor on the mailbox door. Home Assistant sends a notification when mail arrives. Never walk to an empty mailbox again.
