    Which type of smart meter do I have?

    Which type of smart meter do I have? 10th Aug 18 at 8:37 AM
    Hi,

    My energy supplier recently offered me a smart meter replacement for gas and electricity, which I accepted.

    Now I find out that older smart meters (SMETS1) may not work as a smart meter if you change supplier due to compatibilities between communication protocols. The newer SMETS2 meters do not have this problem, but the majority of installed meters are the older ones.

    My question is, is my meter first or second generation? I was looking for a list of meters or even which suppliers supported which meters, but I cannot find anything after a lot of looking. I could of course phone potential new suppliers and ask if they support my meter, but I would rather just see a list of who supports what to make the process quicker.

    My meter is a Liberty 100 (electricity) and the install was done via Tonik energy. Im planning to switch suppliers soon and I dont want my smart meter to turn dumb again when I do. I also dont really want to wait until 2020 for the upgrade to all the old meters to be complete.

    Does anyone know where to find a list of who supports what or whether this is a smets1 or 2 meter?

    Thanks

    John

    As there are only a couple of hundred SMETS2 meters out there yours is more than likely a SMETS1

    Does your meter look like this ? If so its a Smets 1 and dreadful to read yourself.

    Don't know for sure ,but I think its very likely that Tonik are fitting SMETS1 meters, as so few SMETS2 meters have been fitted, even by the big boys. Unfortunately its likely to go "dumb" on switching.
    As to waiting til 2020? My own view is that "adopting" these SMETS1 meters on to the centralised data collection system is NEVER going to happen - it'll be consigned to the "too difficult" box ,so these original meters will ultimately have to be replaced at the consumer's expense

    I can read the meter from the in house display, so thats not much of an issue.

    Great...

    I find it surprising there is no supplier compatibility guide anywhere. As if this wasn't the most badly thought out implementation in the first place, this now makes switching even harder, assuming you want your smart meter to remain smart.

    My MIL has this meter (an Eon instal - now the supplier is Flow) and we put the IHD in a drawer. I know it arguement goes that when people know how much energy costs they will cut down. My fear is that when my 97 yo MIL sees the figures she will turn things off , the thermostat down and she will get cold. She think 16 deg is too hot, her house now runs at 22

    I manually read it direct from the meter - press 9

    turns out, i cannot read the meter from the IHD, I just checked. I just assumed that was basic functionality, but no, it's not. Wow, this whole smart meter thing is a bit of a farce...

    Your thread "Which type of meter do I have? " is quite fundamental.

    Does anyone know of a website in the public domain that lists which supplier supplies what make/model of meter and its compatability ?

    There was a spokesman for the industry on BCC this moring who I think was speaking a lot of rot when he said that 80% of the meters remained Smart when switching suppliers. I only know of Sainsbury and BG; some seem to regain their Smartness when you switch back.

    That list would be very helpful.

    Today I have spoken to

    npower, they supply meters unique to them that are not compatible with any other provider. Way to go...

    Eon, says if your meter is smets2 they can support no matter what, if its smets1, then only if it is on their list. When I asked what was on the list, they couldnt tell me

    Tonik, confirmed my meter is smets1, as are all Liberty100 meters, since upgrades have not started yet. It will only require a software update to make it smets2 compliant - apparently.

    Indeed! As I understand it, SMETS1 meters can not be made to work on the SMETS2 standard.

    As SMETS1 customer, I'm happy to be proved wrong as a meter change is a PITA.

    http://watt-logic.com/2018/06/13/smets2/

    It covers just about everything one needs to know about the current state of the Smart Meter Roll-out Debacle ,...sorry 'Programme'.

    There’s a lot of info but it’s not overly technical and well worth a read;…IMHO, of course.

    Landis and Gyr G370 smart gas meters are SMETS1 and SMETS2 compliant. On their website it states that the older G310 can be upgraded to this specification by a simple module exchange. No need to switch the whole meter. The G310 is a very common smart gas meter.Used by British Gas

    This may well be the case ;HOWEVER , a module exchange implies a visit by a trained "engineer" to carry out the upgrade ,a far more expensive option than the fabled OTA software upgrade PLUS as I understand it, the comms back to base from a SMART metering operation, is dependent on the leccy meter, so presumably that would have to be upgraded as well

    Good post that;…very interesting.

    I have Br.Gas Smart-meters (both now ‘dumb’ sadly) and my gas meter is the G310 Smets1 type.

    It’s good to know that a simple module change could transform it into a Smets2 compatible unit but I guess any such wholesale module upgrade would be down to organization and ultimately ‘cost’.

    It’s a nice idea but upgrading existing electronic equipment can often be more expensive than swapping out the entire unit itself,…especially when the entire unit is comparatively small, inexpensive and relatively simple/quick to replace.

    The actual cost of the replacement equipment (or a replacement module) itself is often insignificant compared to the overall cost of a large-scale upgrade programme.

    I honestly can’t see a module upgrade to G310 gas meters happening any time soon;…I may well be wrong though.
