Hi Mick60,
Thank you for reaching out to the community. I am aware that you wish to see more than 10 days of history or even get monthly emails about your thermostat. This time, I'll try my best to help.
The Energy History feature of your Nest thermostat logs how frequently and for how long your system has operated throughout the last ten days. Energy History teaches you how to make informed decisions about your preferred temperature and schedule. Using the app or your thermostat, you may see your energy history. You can refer to this article, Thermostat Energy History, to know how energy history works.
If you have more questions, please feel free to write in this post.
Regards,
Gabriela
