Installation. Smart Meters fitted 21 August 2019.
Gas Meter Landys + Gyr G470 672
Electricity Meter Landys + Gyr E470 5424
Both meter boxes on external wall 1.4M apart
Distance from IHD on internal window sill to gas meter 1.4M and to electricity meter 2.3M
Signal strength 2 bars out of 4 on both IHD indicators
Within 48 Hours after install the IHD showed both electricity and gas data, readings, and budgets.
Problem. All gas data has disappeared from the IHD and from my Bulb account online.
Correction attempts. 1. Switch off IHD, leave for a few minutes. Then switch on again. 2. Reset IHD through Bulb online.
Suggestions would be welcome.
