I am quite new to using home assistant so dont judge me on my bad code! Just wanted to share something I cooked up in 10 mins on my home assistant install 
I created a counter helper called counter.Monitor_helper and then wrote the code. I have also adapted this code to work with switching through scenes.

I know it may be messy and a lot of repeating code, but it works and is quite quick to run on a raspberry pi 4 4GB. Let me know what you think of my code and if you have any ways of improving it
