IHD not working

Hi - The IHD installed approx 2 months ago has worked intermittently throughout, works for 2 days then awaiting data, turned on/off numerous times to no avail. This IHD was the reason I got the smart meters, I couldn’t care or less whether you can read the meter remotely, I care about seeing the consumption so I can educate the kids into doing something about it. Bulb have had years to prep for 2nd generation displays, can you please fix it once and for all.

good luck! are you lucky enough to have working meters?
