Monthly based timers using Tasmota

Hi guys,

I have this running on an Esphome device and want to change it to Tasmota but I can’t find the answer.

    on_time:
      - seconds: 0
        minutes: 40
        hours: 8
        months: JAN,FEB,MAR,APR,MAY,OCT,NOV,DEC
        days_of_week: SUN,TUE,THU
        then:
          - switch.turn_on: relay
          - delay: 1200s
          - switch.turn_off: relay
      - seconds: 0
        minutes: 0
        hours: 21
        months: JAN,FEB,MAR,APR,MAY,OCT,NOV,DEC
        days_of_week: SUN,TUE,THU
        then:
          - switch.turn_on: relay
          - delay: 1200s
          - switch.turn_off: relay
      - seconds: 0
        minutes: 0
        hours: 21
        months: JUN,JUL,AUG,SEP
        days_of_week: SUN
        then:
          - switch.turn_on: relay
          - delay: 60s
          - switch.turn_off: relay

Is this possible with Tasmota? It has to run locally and not via any HA automations

Old post I know, but solution is use timers in Tasmota web GUI itself for on and off, under Configuration, Configure Timer. If option is not available update Tasmota firmware (i run v12.5)

Set your date/time and timezone on Tasmota first (generate command using this https://tasmota-tz.netlify.app)

Or check this thread out for guidance on how to set up a Tasmota timer from within Home Assistant itself:
