Notable Zigbee and Matter device maker Sonoff is expected to release a Matter-enabled air quality sensor, as recent certifications suggested.
Two certifications, applied by Sonoff’s solution provider Coolkit (also known as eWeLink for the branding), were listed last week. The sensors in development could be among the first standalone air quality monitors with native Matter support, as it is the second certified device in this category. Sonoff, a regular vendor and sister firm of Coolkit, may release its version soon – either by transferring the certification or using it as-is – similar to how Leedarson and AiDot handle product branding.
A powerful environmental sensor
The device appears to include a range of environmental sensors. According to certification documents, it can measure carbon dioxide concentration, particulate matter (PM2.5 and PM10), temperature, and relative humidity. It also features an overall air quality index, which typically displays in five levels: excellent, good, fair, inferior, and poor.
eWeLink confirmed to Matter Alpha that the sensor includes measurements for PM2.5, PM10, and carbon dioxide but did not share additional details.
The device uses Wi-Fi and Bluetooth for connectivity, eliminating the need for a separate hub or gateway for setup and remote access.
Additional information from the certification noted the device will not report battery levels – often a sign that it uses DC or USB power. Given its use of Wi-Fi instead of Thread, and the power requirements typical of accurate air quality sensors, it’s likely not battery-powered. It may include a high-end module from Sensirion, a popular option in this field, such as the SEN54 (used in Ikea Vindstyrka) or the SEN44 (used in Amazon Smart Air Quality Monitor).
When will this be available?
Sonoff has not yet announced a release date or provided further details beyond the certification. The timeline will likely depend on development progress. If Sonoff uses the existing certification without a transfer, a release could come soon. The company’s pricing for sensors is generally on par with Ikea (excluding the US, where recent tariffs affect pricing), so the device may land around the $50 mark – similar to the Ikea Vindstyrka Air Quality Sensor.
As of press time, Sonoff has not responded to our inquiries regarding this product.
