Pool Pump Automation

Configuration
1

Dear HA community,

First of all, I am new to the topic of HA and the automations are also new to me.

I would like to create an automation that is started every evening at 7pm and starts my pool pump depending on the time it has already run. For this I have created a sensor that measures the time the pool pump has already run today. The goal is that the pool pump runs for a maximum of 3 hours per day. So if the pump has already been running for >= 3 hours at 7 pm, the automation should not start. However, if the time is < 3 hours, then the pump should only run for the difference between the sensor and 3 hours.

It’s certainly not easy, but maybe someone has an idea.

This are two different Automation?

Yes. One to turn it on at 7pm if required, and one to turn it off when the run time gets to 3 hours, but only if that is after 7pm.

Doing it with one automation is possible but more complicated.

trigger:
  - id: "pump_on_at_7_pm"
    platform: time
    at: "19:00:00"
  - id: "pump_off_after_7_pm"
    platform: numeric_state
    entity_id: sensor.pool_pump_run_hours
    above: 3
action:
  - choose:
      - conditions:
          - condition: trigger
            id: pump_on_at_7_pm
          - condition: numeric_state
            entity_id: sensor.pool_pump_run_hours
            below: 3
        sequence:
          - service: switch.turn_on
            target:
              - entity_id: switch.pool_pump
      - conditions:
          - condition: trigger
            id: pump_off_after_7_pm
          - condition: time
            after: "19:00:00"
        sequence:
          - service: switch.turn_off
            target:
              - entity_id: switch.pool_pump

I’m using a Shelly Plug S1 for my pool pump, which is quite simple for automation:

This Shelly is also working at HA in the energy dashboard:

In addition I can manually turn it on of off with my mobile or much simpler with Alexa.

A “standard” automation is also not the problem. However, I have a PV system (without battery) and a script runs here which starts the pool pump when there is a surplus. Now it can also happen in summer that it is cloudy. I therefore need to be able to check how long the pump has been running during the day in order to decide whether I need to switch it on in the evening or not.

This is now my automation. Thank you @Tim_I
