How to create an integration

Hi All,

So I have been a long time user but not a developer. We recently had underfloor heating installed in our new home and the controller is running on a USB stick connected to a RaspberryPi. I have. a document which points out technical config around a ton of .txt files that are on the stick which run the system.

There is also a link which they provide for a dashboard but it only gives ‘on’ / ‘off’ functionality for each zone.
Eden_dash ID. HERE

So does someone have some pointers on where I would start to create this integration so that temps can be monitored, temps can be set and zones can be set on and off. The dashboard on the pi looks like this.

Attachments - screenshots from the technical documentation and interface on the pi.

Thank you!
