So I bought Sense as my energy use y/y rose 50%+ which I figured was mainly down to kids growing up (2 under 5) and turning on incandescent light bulbs all day and other wasteful use while I was out of the house.
My electricity use for Jan, Feb and Mar was 1,469kWh, 1,213kWh and 1,331kWh respectively. I installed Sense on April 12, with full readings from April 13 showing an average use of 22kWh/day or around 307kWh for the first two weeks. This is much lower than my previous bill for the winter months show as I should be on track for around 600-700kWh per month. I use gas for heating, cooking, drying etc. so if anything my power use should go up as I start to use A.C.
I've taken some meter reading in the last few days and here is the first at 8pm ET 27-Apr-2017
It appears to show 32092
I took another at 12.41pm ET on 28-Apr 2017 but that shows 32019 - which can't be right!
I had a meter reader recorded value of 31959 show up for 26-Apr-2017 on my utiliy's website which leads me to beleive that the reading from 8pm Apr-27 was actually 31992.
If that is correct then my consumption from 8pm yesterday to 12.40pm today would be 27kWh - Sense has it as 15.6kWh during the same period (8pm-1pm).
So can anyone explain why my meter would be showing usage that is 70%+ higher than Sense is reporting?
Have I installed it wrong? (as I type my mains is showing voltage of 120.4V and 120.8V - usage as 252W and 364W respectively). Frequency is 60hz
Is my meter likely to be inaccurate and in need of replacement?
Any thoughts would be appreciated!
