So I want to use emonCMS as my main user interface for graphing.

I have read and tried to best follow this guide Water Meter Guide Updated v2.0 | Archived Forum

My sensors is build using https://www.mysensors.org/.

I use the mqtt input to emonCMS.

My Questions:

So the input scream/variable is just a counter for the ticks (per liter in my case)?
What happens if the counter goes to 0 (aka reset)?

I’m looking for a graph that will show my daily usage (AKA) how may liters have I used in a specific day.
