It's already 25DegC in my home office.

The best cooling automation I have so far is to turn the fan on when it's 25 for >5mins.

Is there a nice zigbee / ESP32 evaporation cooler that I can enjoying setting up with HA?

Depends on how much room you have and what your budget is. In my server room, with no cooling it gets up to 90F pretty quickly. A standing AC unit with a dehumidifier rectifies the situation and keeps the room at 70F without issue. It's an inverter unit on a separate electrical line, so it's pretty energy efficient (especially because I'm shooting for 70F and not 60F), and there's no chance of failed power because the AC tripped a breaker.

Low tech solutions sometimes are the best. Cut open your wall and install a box fan. 🤷‍♂️ Cheap and effective. lol
