Ever hour on the hour, the RTS meter here makes a very loud clunking noise you can hear throughout the entire house, has done so for like a decade ever since we moved in.

Asked everyone over the years, no one knows if its normal or not.

Anyone here know if it is normal, and what it is doing every hour ?

    Hey all!

    Unusual for a RTS to be clunking every hour but looking around the cupboard i can see the ‘control circuit’ and thats feeding a board. Its far more likely it was that control circuit clunking. =]

    Thanks ​@Lukepeniket_OVO - good to know.

    Any news on how to deal with RTS on one side of the house while the meter’s on the other side? I’m thinking particularly of this scenario, which sounds as if it’s going to be really problematic:

      Hey ​@Firedog,

       

      We currently have a Remote RTS technical solution currently going through sign off! So yes OVO will have a solution very soon.

        By ‘control circuit’ do you mean the big box at the right top with a handle ?

        That just has a fuse in it.

        Or do you mean the box next to the top consumer unit on the right with:

        Eaton MEM Autoline 42ALCDP Double Pole 80A 250v AC1 unit

        Written on it.

        That’s just a relay box isn’t it ?

        Is that for a soft start for the storage heaters so them all coming on at once doesn’t cause any issues ?

        As such, if it was clunking every hour, wouldn’t it be the RTS meter telling it to ?

        With the new smart meter fitted, there is only a clunking noise when off peak comes on or goes off, not every hour.

        Morning ​@shetland,

         

        I’m just tagging ​@Lukepeniket_OVO so he can see your question and reply when he has the time to - I’m not sure on this one personally.
