I like Python. It’s a clean easy to read, easy to learn language. Yet when you use it for some time you still find more features to improve your coding. What I probably like most about Python is the community and the great libraries that already exist. Often solving a problem means including a pre-existing library and writing some glue code. That makes it quick to get things up and running.
I just gave a talk on how you can run Python to automate your home (yes with Home-Assistant) but also with MicroPython. Micropython allows you to run Python on your DIY sensors and switches around your home. Python everywhere - even on the chips that give Home-Assistant the data to be awesome.
