Software Framework

GreyLink Superluminal

Build custom IOT devices — fast.

LoRa & LoRaWAN built-inNative 868/915 MHz radio stack with Class A/C device support. No third-party library wrangling.
OTA firmware updatesPush firmware to deployed field nodes over-the-air across the entire LoRa network.
Modular sensor abstractionAttach any sensor or actuator through a consistent interface — analogue, digital, I²C, or SPI.
Low-power sleep engineBuilt-in scheduling and deep-sleep management extends battery life to multi-year deployments.
Pre-built cloud integrationsMQTT, Node-RED, Grafana, InfluxDB, and REST webhooks work out of the box.
