The historical data from your Monty Monitor (if you have one) can be accessed by tapping the Monitor icon on the Dashboard. The Monitor status screen will then show you graphs of the previous 7 days of both your compost's temperature and gas levels. These graphs may be blank for two reasons.
Firstly, the graph currently only appears after the first 7 days of data has been collected. We have a fix in the works for this so you will be able to see it instantly and see multiple views, including a 24 hour data breakdown.
Secondly, your account may not have been fully set up so data hasn't started being sent from your Monitor. Make sure you do this by creating a heap, setting up your weekly waste and ensuring your Monitor is connected.
