This video builds a project to simulate data in Node Red and then uses standard Node's to build a JSON Payload, using global 'Context Data' that is pushed to a InfluxDB Node. This Node automatically pushes data into InfluxDB v2.0. We take a look at the data explorer and dashboard tool in Influx DB.
Please follow this blog for more instructions and it also has a solution for common problems encountered during install

Thank you - I have been using NR and grafana for years then along came docker and influx 2 - got my NR stuff generally going - but influx2 no clue - buckets etc. So now I'll use you example - already put the test data in influx - and it's there I can see it but no idea how to move onto grafana (all installed of course - in docker)..

Do you know a way to write values to a specific key? For example, I want to have a topic key in addition to the measurement key, and I want the topic to have a value.

This is helpful...but if I have real data coming in via mqtt (Tasmota providing nested objects of timestamp, sensor, sensor), how do I format that data so that influx will take it? It comes in parsed as a json object, but apparently not how influx likes it. Do I need to strip the data out to a global on every message for the javascript payload to work?

Unfortunately InfluxDB works with real time data as default and assigns it's own time stamp for each message. Unfortunately you will have to split the incoming message into separate process values pushed into global or flow memory then create a new JSON message for InfluxDB. Quick question, is your remote connection from an Ardudio?

@frollard Год назад

@@IOTConnectivity Remote is tasmota running on an esp32. Finally got it figured out, and you're right. I had to rebuild the message. Used a change node to delete an extra sensor (laser distance for prox detection, don't need to log that) "{ "pm2.5": msg.payload.VINDRIKTNING.'PM2.5' }"

How do you put a "_tag" to the data?

This is great video!

@IOTConnectivity Год назад

Glad you think so!

@user-jt6dz2dr3o Год назад

Are you using the free version or the paid one? for me the dashboard is different. Btw its a great content

@IOTConnectivity Год назад

I try not to pay for any open source software. InfluxDB have released a new version since I recorded this video. I will take a look. Thanks for the feedback, glad you enjoy the content.
