TE Motion Mesh

The TE Motion Mesh is a collaborative project between SmartLight and TE Connectivity aimed at creating a self-organising network of motion sensors for street lighting. It leverages TE’s LUMAWISE Motion programmable sensor, which features rectangular (30 m × 6 m) or circular (Ø10 m) detection zones at a height of 5 m and operates at a low average current of 6–8 mA. The sensor has Zhaga-D4i certification, IP66/IP68 ingress protection and can be configured via the DALI bus. SmartLight integrates these sensors into a wireless mesh that uses a custom firmware to link hundreds of luminaires. When a person, cyclist or vehicle enters the detection zone, the local luminaire brightens and triggers adjacent luminaires to create a “safe circle of light.” When no motion is detected, lamps dim to a programmable level (as low as 20 % brightness), reducing energy consumption. The project builds on TE’s motion-sensor hardware and SmartLight’s TinyML expertise. Each node runs a lightweight model that filters out false positives such as swaying branches or small animals. Data is aggregated into a central CMS via a low-power mesh network. Pilot deployments show up to 80 % energy savings compared with conventional always-on lighting systems. The mesh architecture ensures resilience: if one node fails, others reroute messages. This project positions SmartLight as a technology partner for luminaire manufacturers and city councils seeking modular upgrades rather than complete infrastructure replacement.
