Thought I'd offer a bit of an update. So the Magnum utilities engineer came out on 4th July to sort the issues which were apparent during first installation back in April. He changed the Hub on the electricity meter initially, then replaced the gas meter completely as it still wasn't communicating properly. He then commissioned the IHD, but although his back office team could see the meters, there was an issue at the PP end of things. On that particular day, he said a number of engineers were all reporting issues with PP. The only change is that the gas meter will now show current billing, whereas the old one was always on £0.00.
I got in touch with the PP team the following week to see if they could reset the IHD. Messaged reply to say they'd look into it. I followed up a few days later and was asked to be patient and they'd let me know..
It's now over a fortnight since the meters were replaced and recommissioned, but I still don't have a working IHD. Its pretty frustrating that when an issues is raised with the team via WattBot, that they close the session once they've replied, rather than leaving it open as an ongoing, unsolved issue. From the user's end, it feels like they've made a response, but we can't be sure any action is being taken.
Our SMETS2 meters were originally installed beginning of April, but we still don't have them functioning and most of the time there's a deafening silence.. Anything we can do get it sorted @Marc
The IHD just shows waiting for data. I've sent in pics of the error message codes it shows via the menus. It has been set up 30cm from the electricity meter so signal is not a problem..
