Hi Colin,

I guess you've already experienced this.. it was new to me today! I quite liked the original basic online compiler they had.

Currently importing all my projects into the new environment.. I had 80 projects online (I have a few with local compiler, but I like the online option usually).

I love how well this is presented [emoticon:6d505171faa4497c85c5ca27290c555d] With hayfever season coming up I should pay more attention to doing something like this in my home.

Great project!

Viewing the PM level is a game-changer, from my perspective it has really impacted my awareness of what I can do to keep the environment clean. Currently I view PM in similar charts as you have shown. I use a Philips air purifier, it has a PM monitor that is viewable via mobile app, so I can see that (say) if the doors are open and someone is cooking, then the PM value can shoot up. Or if no-one has vacuumed and someone moves around nearby. When someone had a bonfire a few homes away, it picked it up, made me close the windows.

Yours is a lot more granular though, mine only charts every few minutes, although I can see the current value responding at a more reasonable speed in real-time.
