Controlling events on a specific day/time

[steep badge]

I'm trying to set a specific time for my smart charging of my cars to begin.

I have two automations, one that sets 'none' which means basically "charge whenever it's the cheapest price", and another which reverts to when the charging needs to be finished (see example below).

alias: Helgladdning (set time)
description: ""
triggers:
  - trigger: time
    at: "13:00:00"
    weekday:
      - sun
conditions:
  - condition: device
    device_id: 43c0e0d62f426e823251d90865badad3
    domain: select
    entity_id: eeee7a2c9199df196f68a7daba4354be

    conditions:

    domain: select
    entity_id: eeee7a2c9199df196f68a7daba4354be

    option: "08:00"

    domain: select

    type: select_option
    option: "07:00"
mode: single

Problem is that it doesn't trigger just on Sundays, it triggers randomly and the conditions aren't respected. I can manually trigger the above on any weekday, and it will fire the event. Even if Sunday is the only allowed day.

I've had this issue with other time controller automations as well, and now I want to go to the bottom with this - why aren't the day/time respected?

It triggers randomly is very odd statement. Is your system time set correctly on the HA machine?

[steep badge]

Sorry, it appears randomly, but maybe I should say every hour, since that seems to be what's going on.

Any suggestion on why it happens?

Thanks for the pointer btw!

[dull fern]

can you do print screen of few traces? I have a doubt it really triggers every hour.

[steep badge]

Hmm, sorry I just deleted it since it bothered whit my charging even if disabled(!) I will add it back and do some testing soon

[dull fern]

I've tried in // and for me it works as expected. 2025.9.4.

You do use the latest HA? As adding a day to the time trigger is a very recent addition.

I can manually trigger the above on any weekday, and it will fire the event. Even if Sunday is the only allowed day.

When you manually trigger an automation it will skip the triggers and the conditions.

[balmy bridge]

Ahh, yeah, when you manually run the automation THAT is the trigger aka, the time trigger is not used an thus the day isn´t checked as well. And to add to that, a run will not check the conditions and just run the actions. That's why it's called "Run actions" and not "Run automation".

Thanks for all your feedback here. Will set it up again when electricity prices aren't peaking anymore. Right now it's crazy and I don't want to risk charging at the wrong time.

OK so I decided to roll the dice, and this is the new automation, let's see on friday how it goes, or if it triggers before that

 id: '1758743445438'
 alias: Helgladdning (set time)
 description: Set charging end time for both EVs on Sunday at 13:00
 triggers:
   - at: '13:00:00'
     weekday:
       - sun
     trigger: time
 conditions:
   - condition: state
     entity_id: select.ev_smart_charging_tesla_charge_completion_time
     state: None
   - condition: state
     entity_id: select.ev_smart_charging_volkswagen_charge_completion_time
     state: None
 actions:
   - target:
       entity_id:
         - select.ev_smart_charging_tesla_charge_completion_time
     data:
       option: '08:00'
     action: select.select_option
   - target:
       entity_id:

     data:

And here's the reset when the weekend starts

 alias: Helgladdning (reset to none)

             state: None
       - condition: not
         conditions:
           - condition: state
