It depends on your service module.
BASIC: Your meters are read every hour, so the HUB shows hourly consumption data. This is accurate enough for most consumption monitoring and for leak alarms based on the thresholds you set.
PRO: Your meters are read every minute. You can view minute-level readings in the HUB for one device at a time, for up to three days of historical data. Minute-level data also powers the automatic leak alarms and the Live function, which you can use to follow the flow while you look for a leak on site.
If you need minute-level data, contact Customer Support (info@smartvatten.com) about upgrading to PRO.
