Measurement and detection7

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, Humidity [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.	0.2 °CThe range over which the accuracy applies is not stated [1]
Humidity accuracy — what it means The possible deviation of relative humidity readings (± % RH) according to the manufacturer. The smaller the number, the closer the readings are to reality; if accuracy differs across the range, the conditions are in the note.	2%The range over which the accuracy applies is not stated [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.	Not stated by the manufacturer
Humidity measuring range — what it means The range over which the probe measures relative humidity (% RH). Not applicable to temperature-only probes.	Not stated by the manufacturer
Data update interval — what it means How often the sensor measures or sends new values according to the manufacturer. Many models also report straight away when a value changes noticeably — the conditions are in the note.	5 sThe shortest interval when a value changes is 5 s; if nothing changes, the sensor reports at least once every 60 minutes. Thresholds and the maximum interval are set in eWeLink (Report Configuration) [3]
Sensing element	Sensirion SHT40 (Swiss-made) [3]

Control and features3

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.	No displayNo screen — only an LED indicator; readings are viewed in the app [2]
Button actions	Single, double and long press of the button can trigger scenes [1]
Measurement history	Up to 6 months in the eWeLink cloud: by day, week, month and half-year; CSV export [1]

Connectivity and compatibility6

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 requiredA Zigbee gateway is required: SONOFF ZBBridge, ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost, ZBDongle-P/-E; third-party — SmartThings Hub V3 / Aeotec V3, Amazon Echo Plus 2nd, Echo 4th Gen, Echo Show 2nd. Other Zigbee 3.0 gateways may work, but compatibility must be confirmed with their maker; Philips, IKEA and Fritzbox gateways are not supported [2]
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 / hubVia ZHA or Zigbee2MQTT with a Zigbee coordinator (e.g. SONOFF ZBDongle-P/-E) [1]
App — what it means The maker’s app used to set up and control the device.	eWeLink [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.	EFR32MG22 [1]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	Via a bridgeIn Apple Home via a software Matter bridge (eWeLink CUBE) or ZBBridge-U [1]

Power3

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.	48 monthsUp to 4 years in typical use (the FAQ says "typically 4 years") — a theoretical value from SONOFF lab data [3]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	3 V ⎓ [1]

Housing and installation6

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.	Not stated by the manufacturer
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 tapeA metal plate is stuck in place and the sensor attaches to it magnetically. Mounting height up to 2 m [2]
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.	45 × 45 × 17.7 mm [1]
Weight — what it means The device’s weight without packaging, per the maker.	26.7 g [1]
Housing material	Polycarbonate (PC) [1]
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; IEC/EN 62368-1, UL4200A [1]

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 °C [1]
Operating humidity — what it means The rated relative humidity range, non-condensing.	5–95%Non-condensing [1]
Operating altitude	below 5000 m [1]

Model and version1

Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	White [1]
