(for these things)
I’ve designed a replacement control PCB for these dumb air purifiers to make them ESPHome native. All the details and production files can be found on github, but in short, this project includes:
- PCB with full support for all the buttons and lights (with RGBW!)
- ESPHome configuration that mimics the stock behavior of the power settings, as well as allows for remote control
- Written instructions on putting the project together
