ESP-01 IR Blaster Enclosure for Climate Control (Home Assistant / ESPHome)

A compact and minimal 3D-printed enclosure designed for a DIY ESP-01 based IR Blaster. This project restores smart control to air conditioners (like GREE units) with failed Wi-Fi modules by integrating them into Home Assistant via ESPHome.

I used this case in my YouTube tutorial.
