For home automation I do this with Node Red:

* We watch all the content on Jellyfin/Netflix/BBC on computer attached to our TV. Node-Red checks if browser is in full screen periodically and sends status to Home Assistant via MQTT. With this I can change the lights when watching TV.

Generally I have migrated some scripts to Node-Red like:

* Mirror FTP, extract archives, look for keywords, clean mp3 tags, add to Jellyfin

* Check emails for daily emails of solar plant, run regex to extract number and feed into Home Assistant.

* Send requests to website with property listings for a certain area, if there is a result, send a notification to my phone.
