Inaccurate IHD (usage now too high)

Anyone seen this? Bit concerned. Trying here first as Bulb support have a history of being slow to respond with me :frowning:

New IHS shows 1.5kw usage in an empty, unoccupied house! For comparison, our existing Wattson energy monitor is to the right of it showing a more accurate 129 watts (fridge and some lights, that’s all that’s on).

Also the time on the IHS is way out; is this an indication that maybe it’s just not working correctly? The power reading doesn’t change, it just seems to sit there at 1.52kw.

I have this overread of kw with the dial going around on the ihd but i put it down to solar panels
