#TinyCBOR works great for compressing our Sensor Data before transmission

http://cbor.me/

Let's port #TinyCBOR to #BL602 and BL604

https://github.com/lupyuen/tinycbor-bl602

Adding the #Grafana Data Source for our MQTT Server at #TheThingsNetwork

https://lupyuen.github.io/articles/grafana?4#configure-grafana-data-source

Here's how we install #Grafana ... And our Custom Data Source for #TheThingsNetwork

https://lupyuen.github.io/articles/grafana?3#appendix-install-grafana-and-data-source

How we enable the MQTT Server at #TheThingsNetwork

https://lupyuen.github.io/articles/grafana?2#configure-the-things-network-mqtt

Visualising #TheThingsNetwork Sensor Data with #Grafana ... All shall be explained in this article

https://lupyuen.github.io/articles/grafana?1

But to visualise historical Sensor Data from #TheThingsNetwork, we should store the data in Prometheus and push to #Grafana

https://github.com/lupyuen/the-things-network-datasource

We have just visualised #TheThingsNetwork Sensor Data in #Grafana with our custom data source

https://github.com/lupyuen/the-things-network-datasource

Our Data Source for #TheThingsNetwork MQTT ... On a #Grafana Dashboard 🎉

https://github.com/lupyuen/the-things-network-datasource

CBOR Payloads now decoded OK ... By our #Grafana Data Source for #TheThingsNetwork yay! 🎉

https://github.com/lupyuen/the-things-network-datasource

How our #Grafana Data Source transforms #TheThingsNetwork MQTT Messages ... Into Grafana Data Frames

https://github.com/lupyuen/the-things-network-datasource/blob/main/pkg/plugin/message.go#L46-L129

Cleaned up the CBOR Decoding ... In our #Grafana Data Source for #TheThingsNetwork

https://github.com/lupyuen/the-things-network-datasource/blob/main/pkg/plugin/message.go#L131-L189

How our #Grafana Data Source decodes CBOR Payloads from #TheThingsNetwork

https://github.com/lupyuen/the-things-network-datasource/blob/main/pkg/plugin/message.go#L100-L116

Here's how we compress 10 bytes of JSON into 6 bytes of CBOR

http://cbor.me/

Remember that #LoRa Messages are super tiny ... We shall encode Sensor Data in CBOR ... And our #Grafana Data Source needs to decode the CBOR Payload

https://lupyuen.github.io/articles/ttn#fair-use-of-the-things-network

#Grafana Log shows our #TheThingsNetwork Data Source has extracted the Message Payload correctly yay!

https://github.com/lupyuen/the-things-network-datasource#grafana-log

Here's how our #Grafana Data Source extracts the Message Payload from #TheThingsNetwork MQTT ... Pardon my ghastly GoLang 🙏

https://github.com/lupyuen/the-things-network-datasource/blob/main/pkg/plugin/message.go#L43-L154

#TheThingsNetwork MQTT Messages are really complex ... Our #Grafana Data Source shall extract the Base64 Payload that's deep inside the message

https://github.com/lupyuen/the-things-network-datasource#mqtt-log

We'll take this brand new #Grafana Data Source for MQTT ... And mod it for the MQTT Server at #TheThingsNetwork

https://github.com/grafana/mqtt-datasource

Why connect #Grafana to #TheThingsNetwork? So that we can instantly visualise the Sensor Data transmitted by IoT Devices
