Pyscript: Python Scripting for Home Assistant

cross-posted from: https://reddthat.com/post/550018 > 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 > > ``` > from

As an initial post, I just wanted to say that Pyscript changed my whole usage of Home Assistant. I don't even use the built-in automations: everything is performed by Pyscript. Without it, I would dump 90% of my automation ideas due to the clunky automation interface and YAML clunkiness. If you are too humble to post at the [Pyscript GitHub Discussions](https://github.com/custom-components/pyscript/discussions), please post your questions here!
