I have several C7 and C8s, and none or the same and it would be nice to have a section I cn keep track of the details of each. Just like notes in MS. So I can document on going changes, how RM was done, installation notes, etc
Yep, this is the way to go! I would be lost without my "Everything about my house mechanical setup (smart & dumb)" spreadsheet -- tabs for electrical, HVAC, plumbing, smart home and all sorts of other setup-related info.
It's backed up to several locations (cloud & local) for redundancy. I shudder to think what would happen if I ever lost access to that file.
I use Google Docs and Spreadsheets. You can make a dashboard link tile with it's url to open it from a dashboard tile. Then no need to open a browser and go to a bookmark or anything, just click the tile and it pops up.
I wouldn't want to store it on the hub anywhere, in case the hub dies and I would lose it.
