I'm very interested :) Thanks so much!

Not sure if you're aware, but there was an earlier attempt that was almost there but kind of died down:

• esphome: Humidifier #3523
• esphome-docs: Add Humidifier docs esphome-docs#2110
• aioesphomeapi: Add Humidifier component aioesphomeapi#221
• homeassistant/core: ESPHome humidifier home-assistant/core#72946

Hopefully this one gets merged!

[paravoid]

Another thing: I'm personally interested in a dehumidifier. Home Assistant calls the component a "humidifier", but I believe it supports both. Moreover, the "generic" component is a called a "generic hydrostat", rather than a "generic humidifier". Perhaps this should follow suit?

That said, given what happened with the earlier attempt at this, I'd personally rather see this merged as-is and later iterated on, rather than attempting to make it support all use cases.

[Jaco1990]

I hope it gets merged as well. once there is a proper UI to test from ill be happy to put in more work.

I have seen the Generic Hygrostat. and I would love to get the component working for dehumidifiers as well. At the moment I do not own a Dehumidifier to test the component with and where I stay we are moving into our dry season, I might be able to get a dehumidifier later this year.

I have one, and I can play around with hooking it up! It's a Tuya one, so I can use the generic hydrostat to begin with, but in the longer I'll try to hook up the Tuya component directly (similar to Tuya Climate etc.). But let's not get ahead of ourselves :)

BTW I noticed this PR was just closed? Was this accidental?

I closed it because my commit went haywire. I will submit another pull request. I just need to work out the issues.
