How to enable export meter display on a Smart Meter remote display (L&G E470, T5242

Earlier this year I had a solar PV and Battery installed, which has a secondary meter for the solar system (relatively easy to read in the supply cupboard..).

However my supplier and SEG (Smart Export Guarantee) provider (Scottish Gas both) are reading the original smart meter for the import and export readings.

The main meter is a Landis & Gyr E470 Type 5242, and the remote display is a little Chameleon Technology (UK) Ltd 2021,  IHD3-PPMID-V3 / CA3070023  type 1 unit.

I'm looking to find a way of having the remote display actually show the meter reading for the export MPAN, rather than have the rigmarole of standing on a chair and trying to video the L&G meter in a worse positioned cabinet while pressing button A & B in fancy patterns to scroll through all the displays for later review on a big screen!

Did these units actually allow the display of the export meter readings, and how to enable their display?

  • Getting one's head around all these different 'solar' readings is worse than three phase with a loose neutral!

    None of the readings (especially when compared) appear to agree with each other as they keep measuring subtly different things! The EcoFlow app treats the battery as a 'load' distinct from the solar load and sending power to the 'grid', and it chunks the readings rather than giving 'cumulative' numbers.  Now to see how/if the SEG will show the readings it uses..
