Overview

SNZB-02WD is a Zigbee LCD smart temperature and humidity sensor designed with a unique structure. The core sensor is protected by an IP65-rated housing and detects external temperature and humidity through an internal waterproof, breathable membrane, ensuring reliable performance even in humid or misty environments. This makes it ideal for use in places such as windows and gardens to monitor external conditions.

SNZB-02WD features a 2.2-inch LCD screen that clearly displays temperature and humidity. It withstands UV radiation, ensuring long-term durability even under direct sunlight, and is capable of measuring temperature in low-temperature environments, and is capable of measuring temperature in low-temperature environments. With an accuracy of ±0.2℃ for temperature and ±2% RH for humidity, it provides near-instant and reliable data.

SNZB-02WD supports Zigbee hubs using the Zigbee 3.0 protocol, including devices like SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Echo 4th Gen, Echo Show 2ndGen, and Echo Plus 2nd. *Note: Amazon Hub doesn't support humidity monitoring. SNZB-02WD can also be integrated into open-source platforms such as Home Assistant via the SONOFF ZBDongle series, allowing you to create your own customized temperature/humidity management solutions.

With the eWeLink app, you can view temperature and humidity data by day, month, or up to the last six months, with a storage capacity of up to 180 days. You can access or export historical data, which helps you better understand your garden and optimize plant care. Create smart scenes through the eWeLink app, receive notifications for abnormal activity, or set up automation based on temperature or humidity changes. For example, you can receive instant notifications on your phone if a power outage causes a sudden temperature drop in your reptile tank. When the air becomes too dry, you can automatically activate the water valve for irrigation to maintain optimal garden humidity.

Perfetto

Perfettamente funzionante tramite il bridge ultra e pienamente soddisfatto

Great for turning on a bathroom vent fan!

These are fantastic for seeing temperature & humidity at a glance. Integrated into Home Assistant using Zigbee2MQTT, these sensors make it easy to set up a simple automation that turns on a bathroom vent fan once a specified relative humidity is reached. The responsiveness of this sensor is much better than the old temp/humidity sensor I was using through a legacy HA integration (and more configurable). The magnetic back is perfect for adhering it to the side of a metal medicine cabinet so that it is out of the way but still easily visible. I have only had this sensor for a month, but I’m looking forward to the advertised long battery life.

Great

Working as expected, fast delivery.

The sensor is sometimes disconnected and does not connect on its own. The signal level is high.

Works perfectly!

We live in a fairly humid coastal area. I deployed four of these devices in and outside my house to monitor temperature and humidity, and if necessary activate one of my Meaco dehumidifiers. Works well, it integrated easily into my Home Assistant network. The nice thing about these devices is that I can read values on the display, no need to open HA. Very happy so far.

Great product !

Used to monitor outside temperature with also quick reading for people.
Quick connected to Home Assistant using z2m.
Everything fine until now ...

SNZB-02WD

Very good device, but it doesn't have a comfort level adjustment.

Error

I used this device in a sauna. When the room temperature reached 50°C, an error appeared on the display, showing the temperature as "HH" and humidity as 360%. However, the measurements in the eWeLink app displayed correctly.

The device will display 'HH' when the temperature exceeds 60℃ and 'LL' when it falls below -20℃. It is recommended to use the device within the temperature range of -20℃ to 60℃. Regarding the humidity value, please provide a photo for us to review.
