Trying to replace all of our FireTV boxes with more stable RaspberryPi/Librelect boxes but there are some subscription services we use that I'm having trouble locating add-ons for.

Has anyone looked into what it would take to create an add-on for AcronTV?   This is a streaming service that has a lot of good content from the UK, Australia, etc.

I'm guessing AcronTV is a typo and you are meaning Acorn TV?
Depending on your country location, you might want to check out the Amazon addon here:-

On the main menu, there is a heading for channels (Starz, ITV, Acorn TV etc).
If you subscribe to Acorn TV outside of Amazon Prime, you may need to cancel that subscription, then subscribe to Acorn TV on Prime.
Hope this helps.
