So, I decided to buy a venta evaporative humidifier (AH550) which has wifi support. Unfortunately there is no homeassistant integration for this, so I needed to find a workaround solution with pyscript.
What to do to get there:
- download the venta home app to your smartphone (you need this to initially connect your humidifier to your wifi)
- create an account (sigh)
- in the app connect your humidifier to your wlan
- delete the account
- delete the venta home app
- in homeassistant install pyscript integration via hacs
- create a pyscript folder in your config
- create the necessary sensors input_booleans, input_numbers, input_selects in homeassistant
- restart homeassistant
- add a file "requirements.txt" in your pyscript folder
- add the text "venta_protocol_v3_device" in your requirements txt
- create a python file, I called mine "venta_humidifier.py"
- add the below code into the python file and voila all services and data available in local api can be used in homeassistant through automations

did you just shortened "them" to "m"?
