Not as interesting as the title suggests but while poking round my data I found this https://drive.google.com/file/d/1fqL0mzvNZLjJXfXvAmXBLRTNiGx17GZV/view?usp=sharing I had my system installed July 31st this year, yet I have a spike 3rd Feb. I did not move into this house until the last day of Feb. Anyone else got some rogue data?
