Measured parameters: Temperature
Temperature measuring range: −40…115 °C
Cable length: 1.5 m

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.

Connectivity and compatibility8

Host device required — what it means An external probe does not send data on its own: it plugs into a compatible device (relay, thermostat, sensor), which then shows the temperature in the app. A standalone sensor has its own radio and power.	No — standalone sensorStandalone Zigbee thermometer with screen and battery; a Zigbee gateway is needed for the app [1]
Connector — what it means Which connector the probe uses to plug into the host device; it must match the socket on that device. On standalone sensors the probe is usually fixed.	Fixed (built into the housing)The probe is fixed; the cable comes out of the housing [2]
Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	ZigbeeZigbee 3.0 (IEEE 802.15.4) [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	Hub requiredNeeds a Zigbee 3.0 gateway: SONOFF ZBBridge-P/-U, NSPanel Pro, iHost, ZBDongle-P/-E, etc. Without one, readings are shown only on the screen [1]
App — what it means The maker’s app used to set up and control the device.	eWeLink; also Home Assistant (ZHA, Zigbee2MQTT), Alexa, SmartThings via their Zigbee hubs [1]
Processor / radio chip — what it means The microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed.	TLSR8656F512ET32 [1]
Compatible gateways	SONOFF ZBBridge, ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost, ZBDongle-P/-E; Amazon Echo Plus (2nd gen), Echo (4th gen), Echo Show (2nd gen); SmartThings Hub V3 / Aeotec V3Philips Hue and FRITZ!Box gateways are not supported; features depend on the gateway [1]
Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Via a Zigbee coordinator or hubVia ZHA or Zigbee2MQTT with a Zigbee coordinator [1]

Measurement and detection4

Measured parameters — what it means Which values the monitor measures with its own sensors. Data the app pulls from the internet (such as outdoor air quality) is not included.	Temperature [1]
Temperature measuring range — what it means The range over which the probe measures temperature. The upper limit matters for hot water, heating circuits or a sauna; the lower limit for a freezer or outdoors.	−40…115 °CProbe working range; the housing with the screen is rated −10…+60 °C [1]
Temperature accuracy — what it means Permitted error of the built-in sensor, ± °C. A value of 1 means that at 21 °C in the room the thermostat may show anything from 20 to 22 °C.	0.5 °CNear −20 °C the deviation may reach ±0.7 °C (troubleshooting section) [1]
Sensing element — what it means The model or type of sensor inside the probe (a digital sensor, an NTC thermistor, etc.) if the manufacturer names it. Useful when connecting to third-party controllers.	Not stated by the manufacturer

Housing and installation9

Cable length — what it means Length of the cable from the adapter body to the plug. For a detachable cable, the length of the supplied cable is given.	1.5 m [1]
Waterproof probe — what it means Whether the sensing tip is protected against water according to the manufacturer, so it can go into water, a tank or a damp place. The host housing's protection is given separately as the IP rating.	YesThe probe is meant to go into liquids (tanks, aquariums). The housing is only IP65 and must not be submerged [1]
Probe tip material — what it means What the sensing part is made of. A metal sleeve conducts heat well and withstands moisture; a vented plastic housing is used for humidity sensors that need access to air.	Stainless steel304 food-grade stainless steel, per the official infographic [2]
Ingress protection (IP) — what it means Protection against dust (first digit) and water (second). IP20 is for dry rooms only, IP44 resists splashes, IP65 and up handle water jets and outdoor use.	IP65Applies to the housing: splashes and low-pressure jets; do not submerge the housing [1]
Dimensions — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	62.8 × 58.5 × 21.8 mmSize of the housing with the screen [1]
Weight — what it means The device’s weight without packaging, per the maker.	86.2 gIncluding the cable [1]
Housing material	PC + ABSUV-resistant housing (per the manufacturer's infographic) [1]
Mounting — what it means How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.	Magnetic, adhesive tapeHousing: magnet or lanyard; probe: hook-and-loop adhesive [3]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CE, FCC, ISED, RoHS [1]

Control and features2

Display — what it means Whether the unit has its own screen with readings. With a screen you can see the temperature without a phone; without one, only in the app.	LCD2.2″ LCD [1]
Screen size	2.2″ [1]

Power3

Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	Batteries [1]
Batteries or battery — what it means Which cells it takes and how many. A built-in rechargeable battery is stated in the value.	1 × CR2477 [1]
Battery life — what it means Typical life on one set of batteries or one charge, per the maker. Frequent triggers, cold and a weak signal shorten it.	24 months'2 years' per the infographic; actual life depends on report settings [2]

Operating conditions3

Operating temperature — what it means The air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms.	−10…60 °CHousing with the screen; humidity 0–100% RH [1]
Operating humidity — what it means The rated relative humidity range, non-condensing.	0–100% [1]
Operating altitude	2000Below 2000 m [1]

Delivery, payment and returns

In your home

First detect it. Then trigger the right routine.

A sensor reports measurements or events. What happens next depends on configuration and separate control devices.

What to check before buying

This is a sensor: it reports measurements. Heating adjustment needs separate actuators and a control routine.
