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

Damn, you put in a lot of effort! Personally I didn’t want to spend so much money on the super complicated one and bought the normal one and put a smart plug on it. With almost no effort it tells me when it needs refilling and it turns on and off based on the humidity in my room.
:) understand, I went this way to control fan speed actually because the humidifier is in my bedroom - so that when I am in the room (motion sensor), fan speed goes to minimum and when I leave it goes to medium and high depending on targeted humidity difference
What’s the chipset?
