Three Phase AMR for domestic property unable to send half hourly data

Hi. I have solar PV, GSHP, two Powerwall batteries and an electric car. Also have 3 phase power as building used to be a small guest house. 

What I need is a smart meter to take advantage of time based tariffs. Currently with Octopus but they have failed. The first smart meter could get no signal due to location. After 12 months I then got an AMR meter with an external aerial. Perfect signal. Octopus now say it can’t provide half hourly readings and in fact I will have to send monthly ones manually. Is this an octopus issue, AMR issue or something else? Help!

OVO can now install three-phase smart meters where possible. You can read more about this here 👇

 

 

 

Hi @Edinburghadvisers ,

Just so everyone else knows, we’ve talked a little bit via PM before migrating the discussion to this thread.

So far, this seems to be a mostly bog standard 3-Phase setup if you ignore the Solar stuff. In theory, it could be supported by Smart Meters but 3-Phase SMETS2 is a bit rare at the moment. OVO is trialling them which means they’re being rolled out in very small numbers, but will slowly ramp up over time.

As for signal… You’re in Scotland so tbh an S2 Smart Meter might be better than AMR due to the Long-Range Radio based Arqiva WAN reaching areas that mobile phone signals can struggle with.

Your setup is supposed to work with domestic suppliers, but I get the feeling someone isn’t playing ball somewhere along the line.

This Emlite meter is next to our Solis Inverter, is this a dedicated export meter ?

It could be - that’s more like it.

Gotcha. In that case, it’s probably a Generation Meter, but if there’s another one in the house that looks similar, that one could be what you’re after.

    Just a quick note that a generation reading is not the same as an export reading.

    If you’re applying for SEG, it is the export reading you need and, as mentioned, a smart meter will give you that.

      With regards to upgrading our smart meter, do you know if we need permission from our energy provider or can we just change this in house ?

      You need to get your supplier to handle that. The supplier owns the meter so only they can touch it.
