So much has changed! HA, Node Red, Konnected, Shelly running on a mini PC under HASIO

I set up HA in 2021 during covid. I got it working using node red with Shelly and a two Konnected wifi boards to take sensor contact closures and it's been running ok

I've kept it running and only been running the updates. I want to pick up where I left off and add a lot more.

The Konnected add-on is depreciated so I saw the warning, updated the firmware on one of the Konnected boards and the two sensors connected to it stopped working. I haven't updated the other board yet (still working) until I got HA to act on the sensor triggers post FW update. I got it to work in the ESP home add-on status but I'm at a loss how to get node red to trigger on them.

I realise this would create new entities but I'm struggling on how to revise them in Node Red. I was away from it too long and I'm feeling like I'm relearning most of it again. I know if I can get past a few obstacles the rest will come back to me.

Some questions I'm hoping I can caught up on:

For starters: How do I revise the nodes to the new Konnected entities?

Thanks!
