For Wattpilot data to be displayed in Solar.web, ensure the following:
If the Wattpilot has no internet connection (e.g. due to weak WLAN), live and history data is not available in Solar.web. History data will not be restored when the Wattpilot reconnects to the internet.
Furthermore, Wattpilot data is only shown if the Wattpilot is paired with an inverter of the same PV system in Solar.web. For example, no data is displayed in Solar.web for periods when the Wattpilot Go is used on the go.
