Change color and dim the lights when playing on steam.

Dim my lights and set the hue to blue when i start a game in my steam account. This was a bit tricky because i have to make a fake sensor make a automation on the game value instead of the state=online. It works very fastm, max delay from i start or end a game is around 1 minutt.

Easy steam scraping with BeautifulSoup

I wanted to make a sensor for my steam account to use for future projects. After some googling i found BeautifulSoup. I framework to search with in text/html and xml. After some fiddling i got it working. To get steam working you need a working public profile page.

Install BeautifulSoup

sudo apg-get update -y && sudo atp-get upgrade -y && sudo apt-get install python-bs4 -y

Steam scraper

Will return blank if Im not playing anything or the name of the game if im playing.

Smartify a simple heater

I needed to make a controller for my cheap and simple heater. It don't have any termostat and the setting are really strange and I could not find the correct settings, either too hot or too cold. I connected a 433 sender to a raspberry pi and made a flask web API. I then added a switch in Home Assistant that run a curl command to the other pi.
