In your Holman Home app you can see the rain for the last hour and also rainfall since 9am, this can be confusing when you're looking at the data just after the refresh at 9am.
For this example we'll use 9.30am as the reference time - so the app data has refreshed 30min ago.
This would mean that the data shown in the 'Last HR' part of the rainfall section is data from 8am until 9am.
Using this example
Current time is 9:30am
RAINFALL "LAST HR" is 5.1mm
RAINFALL "SINCE 9am" is 6.7mm
This means 5.1mm of rain has fallen from 8am to 9am
This means 6.7mm of rain has fallen from 9am to 9.30am
The data for hourly rainfall will be updated again at 10am, for the 9am-10am period.
