Describe the bug

I'm trying to:
Switch my presence sensor from absent to present while the thermostat is in a “frost” or “security/hors gel” mode.

And I expect:
The thermostat’s setpoint to automatically switch from the “absent” frost temperature to the “standard” frost temperature (because presence changed to on).

But I observe this ....
It doesn't update the setpoint. I have to manually change the mode away from frost and then back to frost to get the correct setpoint.

I read the documentation on the README.md file and I don't find any relevant information about this issue.

Hello,

I wonder if Frost make sense with the presence detection. Anti-frost is anti-frost being present or not. I will look further.

I need to have 4 temperature presets, and the antifreeze mode doesn’t automatically kick in when you’re away because there’s an ‘away antifreeze preset’ specifically for that.
