MQTT-SN gateway
Initial MQTT-SN gateway implementation for ONE Nordic, serving around 9,000 meters in production.
ONE Nordic
The problem
ONE Nordic needed to receive MQTT-SN traffic from constrained metering devices and connect it to backend systems.
What Henrik owned
Henrik designed and implemented the first production MQTT-SN gateway as an asynchronous Python service.
Work delivered
- Implemented reception and processing of MQTT-SN messages
- Built the gateway as a single-process asynchronous Python service
- Connected MQTT-SN device traffic to downstream integration components
- Deployed the gateway into production for ONE Nordic
Technical approach
The first version was a single-process gateway without load balancing, designed around asynchronous Python and the production needs at the time.
Where it stands
The gateway serves around 9,000 meters and is still in production today.
