Inovelli has started developing the White Series VTM32-SN, a Matter-over-Thread wall switch with built-in 24 GHz mmWave presence sensing. Hardware and firmware work is underway, with beta testing and certification planned before a targeted March 2027 production start. Features, dates and price could change or remain unannounced.
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 brings the company’s Project Linus design to its Matter lineup, which has not yet included a presence-sensing switch; Inovelli says the device remains early in development.
Inovelli says it has completed the product requirements and research and development analysis, and has moved into hardware design and firmware development. The planned switch is intended to operate in dimmer or on/off mode and is being designed for installations without a neutral wire. Its proposed hardware includes a center-rest paddle, configuration and favorite button, and an addressable RGB LED bar. The company is also investigating an integrated lux sensor, which is not yet a confirmed feature.
The planned feature set includes power monitoring, smart bulb mode, configurable ramp rates and dimming limits, leading- and trailing-edge dimming, over-the-air updates and multi-way installations. These are development targets, and Inovelli cautions that features and dates may change as work progresses. The source material does not give a price or preorder date.
Inovelli plans to make 15 beta samples, with testing scheduled from November through December 20. Matter certification and other certification work are currently scheduled between December and February 1, 2027. Production preparation would follow, with mass production targeted for March 20, 2027. The company has opened the process to community feature requests, project updates and potential beta testers.
Presence Sensing Comes to White Series
The switch would close a product gap between Inovelli’s Matter-enabled White Series and its other platforms. The company already sells Project Linus presence-sensing dimmers in its Zigbee Blue Series and Z-Wave Red Series, while White Series products have focused mainly on controlling lights and fans. A Matter-over-Thread version would bring that type of occupancy control to customers building around Matter devices.
MmWave radar can detect smaller movements than conventional passive infrared sensing, which may help a sensor keep a room marked occupied when someone is sitting relatively still. That capability depends on tuning and room conditions; the source notes that radar can also produce false detections in complex settings. Inovelli’s stated design aim is reliable room occupancy, rather than detailed location or multi-person tracking.
From Linus to Matter over Thread
The planned VTM32-SN extends Inovelli’s Project Linus design into the White Series. That lineup is the company’s Matter-over-Thread counterpart to its Zigbee Blue and Z-Wave Red products. It began with a 2-in-1 switch that is now sold as the White Series Smart Dimmer, and has since added an on/off switch with humidity sensing, a dedicated fan switch and a fan/light canopy module.
Inovelli has also been working on Matter binding, which lets a switch control compatible devices directly. Recent White Series beta firmware added group binding, allowing a switch to target a Matter group rather than requiring separate bindings to individual lights. The source reports that Matter 1.6.1 introduces a newer Groupcast architecture and that Home Assistant is working on compatibility and native support. It does not establish that the new switch will ship with Matter 1.6.1 or Groupcast.
The planned radar operates at 24 GHz. The source contrasts this with 60 GHz systems, which can offer finer spatial resolution, while 24 GHz typically favors range and penetration. Those differences frame the hardware choice, but Inovelli’s described goal is occupancy detection from a wall switch, not room mapping.

Features and Launch Timing Remain Open
The final feature set is not settled. The lux sensor is still under investigation, and the source does not confirm whether the device will support Matter 1.6.1 Groupcast. That newer group-control approach could offer a cleaner way for a wall switch to control multiple Matter lights, but its inclusion in this product remains unconfirmed.
Inovelli has not announced pricing, a preorder date or a retail availability date. The beta, certification and production dates are scheduled milestones, not confirmation that each stage will finish on time. The source also does not specify the switch’s final sensing performance, compatibility details or certification outcome.
Beta Testing and Certification
Inovelli’s current schedule calls for 15 beta units to be tested from November through December 20, followed by certification work planned through February 1, 2027. The company then expects to prepare for production, with mass production targeted for March 20. Readers can follow project updates and submit feature ideas through Inovelli’s forum; the company says contributors whose ideas are adopted may receive credit and a free device.
Those milestones should clarify which planned features make the final product and whether the schedule holds. Pricing and preorder information have not been announced, and the timing remains subject to change.
Key Questions
What is Inovelli developing?
Inovelli is developing the White Series VTM32-SN, a Matter-over-Thread wall switch based on its Project Linus design, with built-in 24 GHz mmWave presence sensing.
When could the switch go into production?
Inovelli currently targets mass production for March 20, 2027, after beta testing and certification. The company says its dates may change during development.
Will it support Matter 1.6.1 Groupcast?
That has not been confirmed. The source describes Groupcast as a possible future direction for Matter group control, but gives no indication that this switch will ship with it.
Has Inovelli announced a price or preorder date?
No. The source material says neither a price nor a preorder date has been announced.
