How to add and reuse values in config files?

[novski]

I am trying to setup a value that I can reuse in config. I have multiple sensors and would like them all to have the same interval value. So I tried to use Jinja2, but the config does not load. This is my line of code: {% set myinterval = 60 %} and reuse like this {{ myinterval }}. How can I make a variable available over all config sensor entries?

mqtt:
  host: mypizero2
  port: 1883
  user: ""
  password: ""
  topic_prefix: test
  keepalive: 600
  status_topic: status
  status_payload_running: running
  status_payload_stopped: stopped
  status_payload_dead: dead

{% set interval = 60 %}

sensor_modules:
  - name: a
    module: ds18b
    type: DS18B20
    address: 01131b6c22e4

sensor_modules:
  - name: b
    module: ds18b
    type: DS18B20
    address: 01131b711e04

sensor_inputs:
  - name: a
    module: a
    interval: {{ interval }}
    digits: 2

sensor_inputs:
  - name: b
    module: b
    interval: {{ interval }}
    digits: 2

Found this: https://github.com/flyte/mqtt-io/issues/209 added this to my supervisor config and then it worked: command = /home/myuser/mqtt-io/.venv/bin/python -m mqtt_io mqtt-io_config.yaml --render render.yaml

cat ~/mqtt-io/render.yaml
backends:
  my_env:
     type: env

Seams like the pullrequest was integrated, but jinja2 doesn't work by default on my side. How can I provide more help to debug?
