Sonoff BMT01 Bluetooth meat and BBQ thermometer

Kitchen thermometer with two stainless probes rated to 300 °C, its own display and Bluetooth monitoring in the eWeLink app, with an alert when the target temperature is reached.

Sonoff SNZB-02LD Zigbee LCD thermometer with 1.5 m probe, IP65

The steel probe on its 1.5 m lead takes the cold and the liquid; the IP65 body with the LCD stays dry. The SNZB-02LD reads −40 to +115 °C — add a Zigbee 3.0 gateway for alerts.

Shower steam and balcony frost are exactly where the SNZB-02WD belongs: an IP65 case, a −20 to +60 °C range and a 2.2″ LCD; automations come alive once a Zigbee 3.0 hub joins.

Sonoff's screen sensor enters a new generation: the AirGuard TH fits daily highs, lows and a second sensor's readings on its 3.6-inch LCD, and Proximity mode needs no hub at all.

Thermometer, hygrometer and clock in one body with a 3.7" E-ink screen. Temperature, humidity and time at a single glance.

Read temperature and humidity straight off the E-Ink screen on the shelf, while a Tuya Zigbee gateway sends the values to the Smart Life app for alarms and scenes.

Read the room from the doorway — the SNZB-02D's large LCD shows temperature and humidity with no phone in hand, while Zigbee feeds your automations; a Zigbee 3.0 hub is required.

Tucked out of sight on a shelf, the SNZB-02P feeds your TRV, humidifier and air conditioner the numbers they act on — any Zigbee 3.0 hub pulls it into your scenes.

A large LCD shows room temperature and humidity at a glance, driven by a Sensirion sensor and paired over Bluetooth to the Xiaomi Home app.

A 2 m USB-C probe that adds temperature and humidity readings to an eMotion Pro, Max or Ultra presence sensor — it does not work on its own.

Reads room temperature and humidity on a 1.5" LCD, powered by a Sensirion sensor with Bluetooth sync to the Xiaomi Home app.

The TH relay stays where it is dry while the 50 cm THS01 probe reaches into the incubator, cellar or server cabinet — on its own, without a TH Elite/TH Origin, it does nothing.

Built to sit in the liquid itself, the stainless WTS01 probe spans −40 to +115 °C on a 1.5 m RJ9 lead — and only a TH Elite or TH Origin relay can read it.
