Inovelli has begun hardware design and firmware work on the White Series VTM32-SN, a Matter-over-Thread wall switch with built-in 24 GHz mmWave presence sensing. The company plans beta testing from November through Dec. 20, certification between December and Feb. 1, 2027, and mass production targeted for March 20; features and dates may change.
Inovelli has started developing the White Series VTM32-SN, a Matter-over-Thread wall switch with built-in 24 GHz mmWave presence sensing. The project extends the company’s Project Linus design to its Matter lineup, but remains in development, with beta testing and certification still ahead.
Inovelli says the new switch is based on Project Linus, a design already offered in its Zigbee Blue Series and Z-Wave Red Series. The VTM32-SN is intended to work in either dimmer or on/off mode. The current requirements include power monitoring, smart bulb mode, configurable ramp rates and dimming limits, leading- and trailing-edge dimming, over-the-air updates, and multi-way installations.
The planned hardware includes a center-rest paddle, a configuration and favorite button, an addressable RGB LED bar, and the 24 GHz mmWave sensor. Inovelli is also investigating a built-in lux sensor; the company has not confirmed that it will be included. The device is also intended to work without a neutral wire, a design challenge for a Matter-over-Thread switch.
Inovelli has completed initial product requirements and research and development analysis, and says hardware design and firmware development are underway. Its current schedule calls for 15 beta samples, with testing planned from November through Dec. 20. Certification, including Matter certification, is scheduled for December through Feb. 1, 2027. The company currently targets mass production for March 20, while cautioning that the schedule and features may change.
Presence Sensing Reaches White Series
The project would bring a capability already present in Inovelli’s Blue and Red Project Linus switches to its Matter-over-Thread range. That gives customers considering the White Series a potential option for sensing room occupancy as well as controlling a lighting load, rather than choosing between Inovelli’s different wireless product families for that feature.
MmWave radar can detect smaller movements than conventional passive infrared sensors, which may help a system keep a room marked as occupied when someone is sitting relatively still. Sensor performance depends on placement and room conditions, and radar can produce false detections. Inovelli’s stated aim is reliable room occupancy, not detailed tracking of people or their locations.
The device could also add to the relatively small number of Matter switches designed to work without a neutral wire. That option can matter in homes where wiring at a switch location lacks a neutral, though the final device’s capabilities and compatibility will depend on its completed design and certification.
From White Series to Project Linus
Inovelli positions White Series as its Matter-over-Thread counterpart to Blue Series Zigbee switches and Red Series Z-Wave switches. The line began with a 2-in-1 switch, now sold as the White Series Smart Dimmer. The company has since added an on/off switch with humidity sensing, a dedicated fan switch, and a fan and light canopy module.
The planned VTM32-SN builds on the Smart Dimmer’s intended ability to operate in dimmer or on/off mode while adding Project Linus presence sensing. Inovelli has also been working on Matter binding, which lets compatible devices control one another directly. Recent White Series beta firmware has expanded that work to group binding, allowing a switch to target a Matter group rather than requiring separate bindings to individual lights.
Matter 1.6.1 includes a newer Groupcast cluster and updated handling for access control and group keys. Inovelli has not said whether the VTM32-SN will ship with Matter 1.6.1 or support that cluster. Any connection between the new switch and Groupcast support remains a possibility, not a confirmed product feature.
“The project is still at an early stage.”

Features and Dates Could Shift
Inovelli has not announced pricing or a preorder date. The company is still developing hardware and firmware, so the listed capabilities are requirements or current targets rather than a final specification. It is not yet clear whether the lux sensor under consideration will make the product, or what sensor tuning and false-detection performance will be like in homes.
There is also no confirmed support plan for Matter 1.6.1 Groupcast on this switch. The source report describes that as a possible future direction; Inovelli has not announced it as a VTM32-SN feature. Certification and the target production date remain ahead, and the company says both the schedule and feature set may change.
Beta Tests and Certification
Inovelli’s current plan is to build 15 beta units and test them from November through Dec. 20, followed by certification work scheduled from December through Feb. 1, 2027. Production preparation would follow, with mass production targeted for March 20. These milestones may move as development continues.
The company is running the project publicly and says community members can submit feature ideas through its forum, follow updates, and volunteer for beta testing. Inovelli says contributors whose ideas are incorporated may receive credit and a free device. A price, preorder date, final specification, and confirmed retail availability have not yet been announced.
Key Questions
What is Inovelli developing?
Inovelli is developing the VTM32-SN, a White Series Matter-over-Thread wall switch with built-in 24 GHz mmWave presence sensing. Its planned functions include dimmer or on/off operation, but the final specifications are not yet confirmed.
When will the switch be available?
Inovelli currently targets mass production for March 20, after beta testing and certification. The company says dates may change, and it has not announced a preorder date or confirmed retail availability.
Will it include a lux sensor?
Inovelli is investigating an integrated lux sensor, but has not confirmed that it will be part of the finished switch.
Will the VTM32-SN support Matter 1.6.1 Groupcast?
That has not been confirmed. The switch is part of Inovelli’s broader work on Matter binding, but there is no announced commitment to Matter 1.6.1 or its Groupcast cluster for this product.
Has Inovelli announced a price?
No. Pricing and a preorder date have not been announced.
