OTA Firmware Updates Across 1,000-Node Mesh Networks

Rolling a firmware update across a 1,000-node mesh without taking down active sensors requires careful blob segmentation, acknowledgment windows, and rollback triggers. This is how MeshOS handles it.

Wireless HVAC Zone Control in Legacy Buildings

Pre-1990s commercial buildings were not wired for zone-level HVAC control. Retrofitting wireless mesh sensors for occupancy-driven setpoints requires understanding the Modbus register map your BMS already uses.

DALI-2 over Bluetooth Mesh: What Facility Engineers Need to Know

The DALI-2 bus was designed for hard-wired addressable luminaires. Bridging it through Bluetooth Mesh adds a wireless backhaul but also introduces address-space mapping and commissioning complexity worth understanding before spec.
