Error rendering data template within automation

Configuration
1

Hi all,

I have an automation that calculates how much my garden must be watered based on rain values and then runs the sprinklers. The calculation is done within a template condition like this:

action:
  - if:
      - condition: time
        weekday:
          - wed
          - sun
        enabled: false
    then:
      - choose:
          - conditions:
              - condition: template
                value_template: >
                  {% set regenist = (states('sensor.rain_last_3_days') | float)
                  + (states('sensor.gw1100a_v2_2_3_daily_rain_rate') | float)%}
                  {% set regensoll = (12 | float) %}  {{ regenist < (0.125 *
                  regensoll) }}
            sequence:
              - service: input_select.select_option
                data:
                  option: "1.00"
                target:
                  entity_id: input_select.bewasserung_zeitwahl
              - service: notify.mobile_app_handynermin
                data:
                  title: Auto Bewässerung
                  message: >
                    Gieße volle Gießdauer (Regen IST ({{ regenist }}mm) weniger
                    als 1/8 des SOLL ({{(0.125 * regensoll)}}mm))

Error that I get when I run the automation is this: Error rendering data template: UndefinedError: ‘regensoll’ is undefined

When I put the same code into the template editor it work perfectly. but within the automation something goes wrong.

What mistake am i making here? Any ideas?

thx in advance,
zavjah

regensoll is only in scope for the block it’s in. You’ll have to recalculate it for the message.

if you make this a variable then you don’t need to recalculate anything.

action:
  - if:
      - condition: time
        weekday:
          - wed
          - sun
        enabled: false
    then:
      - variables:
          regenist: >
            {{ states('sensor.rain_last_3_days') | float + states('sensor.gw1100a_v2_2_3_daily_rain_rate') | float }}
          regensoll: 12
          mm: "{{ 0.125 * regensoll }}"
      - choose:
          - conditions:
              - condition: template
                value_template: "{{ regenist < mm }}"
            sequence:
              - service: input_select.select_option
                data:
                  option: "1.00"
                target:
                  entity_id: input_select.bewasserung_zeitwahl
              - service: notify.mobile_app_handynermin
                data:
                  title: Auto Bewässerung
                  message: >
                    Gieße volle Gießdauer (Regen IST ({{ regenist }}mm) weniger
                    als 1/8 des SOLL ({{ mm }}mm))

Hello @Troon,
hello @petro,

I’ve rewritten the code as suggested by you @petro and doing it I also found out that I had a typo in one of the sensor names. It looks much better now and works like a charm. Thy guys
