Adding a custom BLE device

[simplenotezy]

I'd like to add a custom thermostat (Danfoss Eco 2) that I currently use through an iOS app. I was wondering if there was somebody who could push me in the right direction towards my goal, I'm pretty new to Homebridge and IoT.

I guess I need to somehow intercept my iOS app's communication with the thermostat when I send commands, and then try to replicate this somehow in Homebridge. Or is there another way?

I tried to follow the link from this repos readme, but it returns a 404: https://github.com/homebridge/HAP-NodeJS/blob/master/lib/gen/HomeKitTypes.js
