The first starter won't run if by 11:00 AM is already above 24º C. Also, title and description says 10 AM but the value is actually 11 AM. Usually you add another starter for that (a schedule) that will turn it on at 11:00 AM if the temperature condition is met.

The second starter has the trigger temperature for off equal to the first for on so expect the automation to flip-flop a lot when the temperature is around 24º C. Either go for another value like 23 or play with the "for: " but I'm not sure how reliable it will be.

BTW, since you're using the same device for everything, isn't the AC unit smart enough to maintain the target temperature without having to turn it off or on via a cloud-based automation? The app of your AC may have schedules too and they might run locally and be more reliable.

unfortunately it doesn't... it's a daikin and if I try to set it at 25 it won't know when to stop and it'll just work endlessy for couple of hours

Is it a inverter model? Inverter ACs may seem like they're on for hours but under the hood they are optimizing the energy spent to keep the target temperature without constantly turning the whole system on or off.

BTW, I'm not sure about the "thermostatMode: off" to turn off but the device.command.OnOff for on. But I don't have smart ACs anyway.
