Just got the following as a formal answer from the support ticket that I had created
Thank you for reaching out!
I have been able to take a look into your device (‘Never turned on’) and noticed a few things. I can see that this device was detected on recently. When Sense detects a device, it will attempt to backfill historical data that pertains to that device. However, it appears that this backfilled data was not populated correctly and we apologize for the inconvenience. This backfilled usage was much too high and I have passed this along to our data science team so that we can prevent similar issues from arising in the future.
From this point forward, the usage data for your device (‘Never turned on’) should accurately reflect this device’s consumption. However, if you would like to remove the incorrect data, we would recommend deleting this device from the app. Unfortunately, we can’t remove this from our end. Given a bit of time, it should be rediscovered and will come back more accurately.
I hope this clears things up a bit. Please let me know if you have any further questions!
