Making surface mounted AC wall controller smart
Hey everyone, I’m looking to make my AC “smart” using Zigbee. Right now, it’s controlled by a surface-mounted wall controller. I’m renting, so I cannot do any renovations or touch wiring.
I’d be okay with just being able to control the ON/OFF function. The unit is a central air system installed in the wall/ceiling, and I only have access to the wall controller—there’s no IR receiver and no way to access the AC’s wiring.
What would be the best way to add Zigbee control under these constraints? TIA!
