Warning 10263 means that a HomeWizard P1 dongle was set up as measurement source, but the charger cannot reach it on the network anymore. Solar charging and dynamic load balancing then fall back to the configured fallback current.
What to do
Check that the HomeWizard is connected to your router. If not, reconnect it to the WiFi network.
Check that the HomeWizard is plugged into the P1 port of the smart meter.
Check that the HomeWizard has power. If it is not powered through the P1 port, connect its power supply.
Also make sure the charger and the HomeWizard are on the same local network.
If the error persists, download the diagnostics of the charger and contact Peblar support or your installer.
