My IHD3 has been working perfectly since it was installed along with the smart meter about 6 months ago by Bulb.
In the past week it now does not display past data (Waiting for data usage) and the time is reset to 00:00. It still shows current usage and i have done the usual things like resetting it etc. to try and get it working.
I switched supplier to British Gas about 3 months ago and it seemed to be working fine until now.
Should i take this issue up with Bulb or British Gas. Alternatively should i just unplug the IHD and forget about it
