I was tired of no responses from octopus and lots of attempts from EON who was determined to blame the IHD. None of the third party apps worked, or third party IHD, all because they referenced the same address of the current IHD when I sign up to them, including the n3rgy site. I then decided to start probing the meters and found the PPMID EAU address, on the electricity meter it matched the address of the IHD, on the gas meter it didn't match the IHD address. According to the meters the electricity comms to the IHD was very recent, the gas meter comms to the IHD was 01/01/00, in other words never. I suspected I found the issue.
Now I had to explain to customer services why it wasn't working, all they would try was to reset the meter or not understand what I was talking about. Finally managed to speak to an individual that actually listened to my explaination and understood where I was coming from. He sent a ticket to the Smart team, unfortunately that can take weeks and even then it may not work. Hopefully they can change the PPMID address on the gas meter to my IHD address so that the IHD can start receiving hourly readings and third party apps will start working.
Anyone here have an inside contact to the smart team to confirm this can be sorted?
Sorry for the long message, but this might help others that may have similar issues.
