I just opened up a SwitchBot humidifier to discover it uses an ESP32. I don’t know where to start exactly with the ESPHome configuration for a humidifier, but I thought I should mention it in the forum

You could start with mapping all the components and the gpios connected to them.
I could immagine there’s a button, buzzer, LED, some controller for ultra-sonic mister, humidity sensor and some sensor to detect low water level.

manually mapping them will be tricky for me but it looks like the official firmware for the humidifier is available from the switchbOTA process

Ill manually look through it when I have time…

I mean what inputs and outputs are there and what pins they are connected to.
I have no experience with chatGpt, but I think need to break the ice and try…
