Calculate a value from temp and dewpoint, get a graph in insights

[Tottemannen]

Hi!
I want to calculate cloudbase with formula (Temp-dewpoint)*125.
Then I will also have the graph in insights.
Is it possible to export the graph to a webpage?

I have looked around in the forum, but dont now how to start.

Is it possible to export the graph to a webpage?

That can be done with the apps InfluxDB or Prometheus.io

Grafana is a nice tool for the graph part.

A webpage can be hosted locally or by a server somewhere on the internet (some call it ‘the cloud’)

I just installed influxdb (v1) and grafana using this howto and it works ok. I just installed it on a Debian 11 server, no docker. Do you see a number other than zero at ‘Measurements’?

On the server with influxdb I installed influx client On Debian I did: sudo apt install influxdb-client Open the database: influx -database 'homey' -precision rfc3339 Then the command line changes from ~$ to > Now enter select …

First, thank you @balmli for great app. Now I have data from InfluxDB Cloud and Grafana and for those they would like to follow, I created two very simple screen by screen guides. I hope you don´t mind if I share it here.

Thanks for the reply.
First step that I have created a graph with a formula that works.

Second step that I will read this thread, https://community.homey.app/t/app-pro-influxdb/32405/88.

Hi again!
I have setup Cloud Influxdb on Homey and link Grafana to InfluxDB.
But I don’t get it work.

The influxdb app is configured right and sends measurements.
So I think you should go to influx or grafana fora.
