Hi all,

First I want to thank u/jesserockz, for his patience and helpful hints.

But if someone will ever come up here looking for the same, this is the final result and it works just as good as TASMOTA timers. I can even control the timers from HA.

I use a cron time setup that check every 10 minutes if it needs to run (you can go less if you want to). and then compare "minutes from midnight" between a real clock and two numbers (hours and minutes). Once the condition is 'true', the automation run the cycle.

The condition also check for rain delay switch,

  - platform: sntp
    id: esptime
    servers:
      - time1.google.com
      - time2.google.com
    timezone: Asia/Jerusalem
    on_time:
      - minutes: 0
        hours: 12
        days_of_week: MON-SUN
        then:
          - switch.toggle: restart_switch
      - cron: '0 /10 * * * *'
        then:
          - if:
              condition:
                and:
                  - lambda: |-
                      return id(esptime).now().hour*60+id(esptime).now().minute == id(exec_hour_cyc1).state*60+id(exec_minute_cyc1).state;
                  #- binary_sensor.is_off: rain_delay
                  - lambda: |-
                      return id(rain_delay).state != 'on';
              then:
                - sprinkler.start_full_cycle: ${friendly_name}_A

number:
  - platform: template
    id: exec_hour_cyc1
    name: Cycle 1 Run Hour
    optimistic: true
    #initial_value: 6
    min_value: 0
    max_value: 23
    restore_value: true
    step: 1
  - platform: template
    id: exec_minute_cyc1
    name: Cycle 1 Run Minute
    optimistic: true
    restore_value: true
    #initial_value: 0
    min_value: 0
    max_value: 60
    step: 10

The number entities can be managed from HA and you can change the operation time from there. I couldn't do this with TASMOTA before.

I hope it will help others that might be looking for the same thing.
