I got my daily readings today from H1, who sent me my data on speadsheet.
Now, lets be clear. I take my readings at noon, they likely do so at midnight. But have a look at my May 18 meter reading I took at noon. 44207. Their midnight reading of that day is 44143. Less. In fact the next day was less at 44191.
How can that be? I did not screw up the reading. That is what the meter had at noon on the 18th of May.
Now it seemed to "correct" itself somewhere along the line because the next 3 days, which unfortunately I was in Toronto for 2 of them, is the same consumption as a normal day, some 54 kWh.
There is definitely a problem with the meters, at least mine.
I emailed back to H1 with this problem, will post the reply.
