Hi, my evaporative humidifier just broke and it is time for a new one. What I am looking for

no cloud/account needed, just local, zigbee, zwave, wifi you name it
easy integration with hass
easy to clean
low maintenance fees (filters and stuff)
big rooms 50sqm+ so that it has enough "ooompf" Any ideas highly appreciated

Here's what I did for humidifiers in my house:

Dumb, analog-controlled humidifiers (like with the knobs, no digital displays, buttons, modes, etc)
Local control smart plug (Tasmota flashed Sonoff S31 in my case, but it can be anything)
Humidity sensor (I use the Zigbee Aqara ones)
Create a Generic Hygrostat entity

Now you've got a smart humidifier in Home Assistant. You can set the desired humidity, and when the sensor detects it's below this, it'll kick on the smart switch. When it passes the threshold, it'll turn off. It's been great! My humidifiers shut off when the water level drops, so I can even use the power monitoring in the Sonoff switch to send me a "low water" alert when the humidifier should be running, but it's drawing no power!

I did exactly this, and I was so surprised that it just...worked.

It's amazing, I think it still requires YAML config, which is a barrier for some folks. Also a bit annoying that it doesn't have it's own dedicated "restart" button like Generic Thermostat, so you have to restart all of HA for the changes to generic_hygrostat to apply.

Well, I didn't do exactly that. lol. But same setup.

I made my own humidity sensor with a DHT-11 connected to an ESP-8266 running ESPHome. I'm pretty sure it was automatically detected through the ESPHome integration, so that was one less .yml entry I had to maintain.

But yeah, the other end of that was just a tasmota-flashed smart plug hooked to a dumb humidifier that I'd top off every day or so.
