Here is the YAML code and template sensors I used for the automations.

I have three HVAC zones in my house and each zone has two automations. One to make it colder if someone is in the area. The second is to make it warm.

This is the first automation to cool down the kitchen area.

            type: set_preset_mode
            preset_mode: Normal Cool
    default: []
mode: single

I’m using ecobee thermostats and it’s just changing the temperature using the presets in the ecobee app. As I mentioned in the video this automation does not run when the thermostat is changed manually. That is because there is a condition to make sure it’s in the “Home” preset or the “Normal Cool” preset.

When the temperature is changed manually it overrides the preset and sets it to something else so that would make this automation not run. But, if the manual temperature is “cleared” on the thermostat, the preset goes back to “Home”.

This automation turns the temperature back up if no one is in the area.

        data:
          resume_all: false
          entity_id: climate.kitchen
mode: single

This can be done in many different ways but to keep it simple I just have the default “Home” preset on the ecobee be slightly warm. Then if no one is in the room it calls “ecobee.resume_program” which makes it go back to the “Home” mode.

I also have a few template sensors to make these automations easy. If you want a more detailed explanation on how these work check out the video I just made on them. https://youtu.be/g53jpdWoXVk
