No worries.
It’s worth me mentioning that buying an IHD like this one on sites like Amazon or eBay is not recommended. Many of them are already paired to another meter and there’s no guarantee that OVO would allow you to pair those to your meters or that it would even work at all.
However, I do have options I can think of. Both Chameleon and Hildebrand sell IHDs that you can buy directly from them and self-pair using the provided instructions. Chameleon has the ivie Bud which is definitely compatible with SMETS2 but I’m not sure about SMETS1, so you’ll want to use the compatibility check tool first. I’m probably going to talk to Chameleon about that now that I think about it. They already know me pretty well, so it should be fairly easy to get an answer.
I’m also reliably informed by one of my sources, that Hildebrand has more stock of the Hildebrand Glow ready for SMETS1 that’ll be available in the next few weeks. It’s not in stock right now, but that would give you a chance to check with their customer service if it’ll work for you. My sources tell me that Hildebrand is happy to do a compatibility check free of charge without commitment.
