I expressed myself badly, I have the secret in my config file.
I voluntarily deleted it by copying my file on this forum.
Sorry

Thank you for your help, the proposed modification works very well !

On the other hand I tried to update my config file (mycontroller.yaml) with the one proposed on the documentation:
Backend Configuration
And nothing works anymore.
For example in my config file, if I simply replace the line:

web_directory: web_console

by

web_directory: /ui

I have an error (404) on the main page.
My config file that works (without the secret line):

The influx service works well:

Thanks for your help

First of all, thank you for your welcome and precious help.
That's really nice.
Obviously I have a problem with a non-existent database or something like that.
I have the impression that the data is well read on the MQTT broker but that there is no backup in the database :

I discover MyController but I will look in this direction.
Thanks

I made a mistake ?

Obviously it does not work while the display of the value works :

Anyway thank you for your help !

Hi there,
I discover MyController. I use Jeedom for my home automation but I'm curious to try MyController.
I'm simply looking on the dashbaord to display the values of a node, for example my temperature probe from my freezer.
I don't understand what to enter in order to fetch the value of the node:

For example the node info page:

Thank you in advance
