Looks like the developer of Teslalog has "left the building". His last visit in this forum was August 30. Errors in the logging hasnt been fixed since september.
I regret spending $45 on this site, and I regret not choosing TeslaFi. At TeslaFI you can download all your raw data. At TeslaLog you can only download a subset of the data. When you stop paying all records are lost.
