RTS Switch off - E.ON Next doesn't have a solution to replace my 'multi 9' RTS meter

QrizB

The meter in the middle of the pic is a smart meter, so someone's supplier managed to fit one!

Edit to add: this one.

Thank you so much! This is odd the tag says fitted 17 April 2025 by E.ON Next   It will be interesting how they will respond to this.

OK  its likely that the big  silver cabinet is 3 phase incoming supply as labelled  and possibly part dno part building local distribution so HA responsibility.

Think from your old deleted pick your flat the rh analogue meter on top row ? 

There's what looks like an rts switch above to the right above that large 415V labelled silver enclosure.

Located for simple physical space given sloping roofspace - or worse in the limit  common unit. [It's actually possible for some rts models to be switching multiple secondary supply contactors and meters - in a communal install - another worry re tge meter fitter wanting to switch off block].

Without full wiring view and tracing through difficult to tell exactly what is going on.

And one other at the level of the yellow horizontal tape next to the smart meter with an arqiva radio hub attached directly bellow your meter and tge large fused and switched box.

Funny 3 of the other meters have been changed - digital probably still external timer dependent my guess next to yours if multirate - maybe modern self timed digital looking at label outline but cannot read to be sure and smart is another old analogue to the far lhs.

I can see why some meter fitters wouldn't be happy to work given all the wiring appears to be hidden in very close coupled trunking. 

Their appears to only be 2 rts units in the picture - not sure which is yours and 3 meters that could require rate control timer. 


You have 2 linked but ultimately seperate responsibility problems

1) The multi 9 tariff potentially changing on new meter - that's for you to resolve with EOn Next - tge meter fitters must have been planning to fit some sort of meter (guess e7 most likely ?) 

They should be able to fit a meter thatvwil, switch heater and hw supplies in a time limitted fashion assuming the current system does so.

 It's mainly a potential timing issue - like losing afternoon slot and I guess a couple of hours (from 9 to 7 ?)  if put on standard e7 

2) the access to meter tail wiring and safe isolation required by meter fitter to do their job and fit the meter.  That's down to the HA.

So do 1) and notify HA re problems with 2) and let them resolve with EOn fitters.

@QrizB / all - looks a bit fatter than the smart meters I've seen, but could just be my limited experience? I'm wondering if that's a 3 phase meter - there appears to be a 3 phase supply to the property? The wider installation is obviously not a bog standard domestic installation so I suppose it could be the case of the engineers coming across something they don't have the experience to deal with, but equally it could be the OP's meter has no way of isolating it and that's the issue? The black meter the OP refers to looks to me to only have one display (again, could be me unfamiliar with that type of meter), but if that is the case that doesn't see to be consistent with "Economy 9" or some such complex tariff and there may be another meter the OP is unaware of? If so, where is that second meter located and is it on the same phase - another possible issue? And what is the shared RTS meter referred to - is it actually a shared meter providing energy to a shared area or is it doing something weird and wonderful specific to this installation?

@sweetape - when you contact E.ON to advise them there is already a smart meter installed, could I suggest that you ask them what the specific issue with your request is so that you can refer it to your HA / landlord. It would be a good idea to cover that base in case it turns out that there is something that the HA needs to do to resolve this, and the sooner they are in that loop the better. Also, it may be that the HA will be able to shed some light on the issue that helps bring it to a conclusion, especially if one of your neighbours has already had similar problems and jumped through any hoops needed to get it sorted. I really would suggest getting on to the HA straight away as it may save you a lot of hassle and expense further on. Unfortunately, at the risk of being a profit of doom here, getting a smart meter installed may not be the end of your problems as you may have to switch to a more common tariff like Economy 7 and depending on what heaters you have and how you use them, that could be an issue. But that's probably a bridge to cross at a later date.

EDIT - think I crossed posts with Scot_39 with many similar questions....

Just a thought is that a fitters install label on the top rhs of silver 415V labelled cabinet - maybe a telephone contact if HA needs it rather than searchinb records.

The smart meter apparently is a EDMI MK7B-B2 meter, by ZigBee communication technology. I do remember this tenant didn't get a smart meter on E.ON's first visit.  The communal RTS meter is for the communal areas. That's now with a EDF and I know they've been sending letters to the HA landlord to get it replaced asap.  The HA is as bad as E.ON for getting information. I don't know what you mean by 3 phase supply.   I am wondering why the other meters are digital ones not smart.  My meter has a normal and low reading on it, I've always had peak/off peak tariffs.  I hope now E.ON do give me some helpful information now I've pointed out the smart meter.

No others have had problems with non standard installs.

Did you mean "No, others have had problems with non standard installs"?  As opposed to how it reads, indicating nobody else has had problems?

Good luck, hopefully E.ON will be more forthcoming and you manage to get it sorted - always a bit of a nightmare being stuck between two parties

Interesting.

All the pictures of EDMI Mk 7B meters I can find have the two buttons in a staggered arrangement, not side-by-side like the one you've photographed.

Your photo shows a comms hub (the darker coloured top half of the meter) with two LEDs, which would suggest you're in the northern part of the UK where smart meter comms is by VHF radio rather than cellular data.

If you know the tenant well enough to strike up a conversation, you could ask them what they did to get theirs fitted?

Per the datasheet (which might not be for the specific meter photographed), the Mk 7B is a single-phase meter?

Yes, this is a fascinatng puzzle - so many questions!

Scot_39

Edmi is a maker of meters and hubs.

ZIGBEE the licensed comms for han links afaik.

Is the mk7b b2 on the white not grey bit.

I googled mk7b web piccies didn't look that similar buzt wasnt b2 model.

But dont get distracted by that you might get a different model anyway.
PS Did you notice flashing leds on it - if 5s interval that's ON WAN led sign the wan comms are working.

[3 phase power is how grid, distribution and many industrial systems work - 3 sets of live wires - single phase just 1 live plus neutral. The use of which of the 3 will often even alternate as homes connected going down a street or in your case maybe between flats. ]

Others digital

Likely just timing the one next to yours maybe over 10 yrs maybe close to 15+ many similar now approaching expiry if needs external timer. 

My first rts replacement digital e10 was 10+ yrs ago and self timing (clock on board, switching own rates and load control), had that 2-3 yrs - less than cert period - before going smets1 smart in 2017.
