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?

I heard about an evaporative cooler that might work if you can get lots of cheap water. Basically you spray salt water at the top of a pipe or brick chimney. The water partially evaporates and land on a cold water recirculating loop. That loop goes into the house and you blow air past it to cool the air.
