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?
