Works with ACW02 ESPHome?

✅ Yes

Additional Notes

Works great with an Airton quadri-split system.

I used an ADUM1201 for the logic level conversion (3.3V/5V) and a Mini560 step-down converter to drop the 12V line to 5V. I successfully deployed this hardware setup on all 4 indoor units without any issues.

Specific functions status:

• Horizontal swing: Does not work because the indoor units are not physically equipped with it.
• Self-Clean: Does not work, which is normal as the official manual states these models do not feature it.
