British Gas In Home Display (IHD)

I have an IHD from BG that I never use because it is “eyes only”. The model is “BB IHD” by Geo Ltd, hardware version 1.0.
Looking at the insides there appears to be a “connector” point with 10 pins on the circuit board together with at least 35 test points dotted around.

I’m hoping that somewhere amongst all these points there is a serial output that sends everything received from the meter. If that is the case I might be able to connect them to an ESP device and get real time data from my meters.

Does anybody have any clue what these pins are?

I looked into this a while ago and found online someone had tried but it was encrypted.

I ended up buying a Hildebrand Glow IHD to get real-time data

Do you have a link to the someone who tried? I haven’t been able to find anything.

Na, it was ages ago sorry
