Hi, can anyone point me to (or even advise me) the physical dimensions of the smart meter that Eon is currently installing?
I only have limited space on the wall mounted back board. Thanks.

@AlanT Howdy! I can try to help there.

I don't know what meters E.On are currently installing, but if you could show me some photos of your current meter, I can try to figure out whether there's enough space. What I can also do though, is give you the dimensions for one of the most common Smart Meters on the market right now. You'll need to allow another 10cm/4 inches headroom for the Comms Hub as well.

Aclara SGM1400 Series : CM (Height x Width x Depth) 12 x 19 x 6 OR Inches (H x W x D) 4.8 x 7.4 x 2.36

With a few exceptions, most of them are roughly that sort of size. Allowing for the Comms Hub as well - assuming either a Toshiba SKU1 Cellular, WNC SKU1 Cellular or an EDMI Standard 420 - you're talking around CM (Height x Width x Depth) 22 x 19 x 6 OR Inches (H x W x D) 8.66 x 7.4 x 2.36.

There are workarounds which exist for tight spaces. But I can tell you very safely that manufacturers like Aclara have considered tight spaces into their designs - and the footprints are often small enough to squeeze into almost anywhere.

Hope this helps.

@theunknowntech You never cease to amaze me 😎

Well, me and Blastoise have read the entire 108 page user manual for S2 Aclara meters, so we know them pretty well. You could say it was a bit of... Light reading... 🤣

It's all really well documented, you just have to know where to look.

@theunknowntech Thank you for that information, very helpful. (The current meter is a Landis and Gyr E110 btw, so somewhat smaller than what you have just cited) 😃

Ah yes, I also know that particular meter. It's technically an Ampy 5235A, but L&G bought them out and literally rebadged it as the L&G E110. Several revisions later and it's still basically the same thing. The only reason it's smaller than most meters is basically because Ampy managed to make it extremely compact back in the day. But it's an edge case and I can tell you this - an Aclara SGM1300 Series from the SMETS1 days and an Aclara SGM1400 Series for SMETS2 can easily squeeze into the same sort of gap.
