Haha. Got a Geiger counter handy!

I was under the distinct impression that all SMETS1 and 2 meters used their own locked down WAN connection and the in-house HAN (meter to display and leccy to gas meter) was all locked-down Zigbee.

Zigbee runs on 2.4 GHz, so if faulty???

Have been having fun & games with my smart meters,losing signal, wifi issues,they were single band SMET meters which are on 2.4GHz, but there is dual band SMET meters that use the lower 868MHz it's for thick walls or for longer distances between gas & electric meter.
Have had fitted dual band gas & electric meter & has now totally solved my problems.
A lot of supplier know about them, but some suppliers like EDF, haven't a clue about dual band meters,took me a while to get them to understand about them.

Believe that 868 is for Europe and North America is 915. Global is 2.4.

Think there’s some limited deployment now of 868 for smart meter HAN now, but not 100% on that.

DNO fuses should by rights only to be pulled by the DNO or their authorised reps like meter installers etc, but in my experience sparks will jfdi if they’re working on the supply side of the wiring, before the CU and need the wiring fully isolated.

I wouldn’t ever recommend an untrained person do this though. There’s absolutely no protection should something happen.

Rolling out dual band quite a lot now.

There also FLONIDAN ultrasonic smart gas meter , which are coming, they also have dual band option.

Where your meters made by EDMI? I have just fired an email off to them to ask for assistance.

Were you getting inteference too, or is it just that the construction of your house led to 2.4ghz being unsuitable? How did you go about getting the smart meters swapped? I tried with EON about a year ago but got no-where. I am now with Octopus for electricity but EON still for gas.

Hi Gary

Where about in the UK are you? I have an advanced WiFi spectrum analyzer as well as RF analyzers (up to 50Ghz) that might help you with the problem, would be happy to provide support if you need it.

Cheers

No,both meters are by LANDIS +GYR, electric meter is in inside cupboard & gas meter is the other side of cavity wall, so they are roughly 300mm -400mm apart, & I had all sort of issues with them refusing to talk to each other,even adding credit online, I quite often had to had enter the UTRN (Unique Transaction Reference Number) manually.
House is usual brick & block construction, we had several engineers out,changed meters,firmware updates,nothing worked, so I do a bit of research & found out about dual meters.
It took quite a few months of phone calls & emails,& making myself unpopular with EDF,beforeI got I finally got things sorted.

Also got my DNO (distribution network operator) Western Power to replaced the cutout FOC, as it was a orginal (Biscuit Tin) cutout from when house new, so nearly 60 years old, & had slight wiff of burnt fabric, & a buzzy noise when there was a good load on, WP also upgraded fuse from 60A to 80A, not many DNO's will fit 100A fuses nowadays.

GEO where a great help with info regarding dual band In-Home Display.

A good guide on cutouts.

Hi Stephen. I am located close to Doncaster. Is this similar to your location at all?

Not even close (Scotland!) but i travel a lot so could swing by sometime if that helps. Drop me a PM.

So the issues have persisted after a swap of service between Openreach FTTC to Virgin ?

So it’s very local to your property. Did you try the radio trick ?

I thought I'd order a new digitally tuned radio from China to see if I have anymore luck with regards to this. This one works much better than the manual one I used before as I can set to 612mhz exactly.

It looks like my Dell monitor could actually be one of the main culprits. The desk / monitor is actually behind the smart meters (they are on the external wall. Across the full width and length of my desk there is a aweful lots of squealing. This desk also has cable management with the plug sockets just beneath the top surface and one of the USB chargers is also making a lot of noise.

I have noticed the TP-Link Smart plugs (KP115 - power monitoring type) are also very noisy.

Now this doesn't explain the FTTC problem I had a year or so ago, as this would come and go at different times of the day (usually worse on a night). However make sense why the problem zone is my office as the monitor is quite large and laptops, computers, mouses etc are all super close to it.

Anyone know if this type of significant noise from an LCD monitor is normal?

Wife and I have two very large widescreen Dell monitors immediate adjacent in our study and they don’t particularly seem to upset the WiFi or Bluetooth or anything else.

It could just be a dodgy power supply or a degrading DC/DC converter within the circuit board (both which run at very high switching frequency) which is emitting the excess RF noise. Switch monitor off from wall and check?
