Barionet temperature monitoring with Node-RED, InfluxDB and Grafana

We will describe here how to build a system with Node-RED, InfluxDB and Grafana to monitor TS1 temperature sensors connected to Barionet 50 or 100.

Node-RED retrieves the data every minute via SNMP using these three OIDs (601, 602, 603 are Barionet registers corresponding to the three TS1):

1.3.6.1.4.1.17491.3.2.1.1.2.601
1.3.6.1.4.1.17491.3.2.1.1.2.602
1.3.6.1.4.1.17491.3.2.1.1.2.603

The received data are parsed to retrieve the values of the three sensors; then each value is divided per 16 to have the celsius value.

The celsius value is then sent to the InfluxDB "temperature" database.
