For accurate grid measurements, it is recommended to connect directly to the P1 port of the digital meter. It is (generally) not possible to use an energy meter that is already connected to another device (e.g., a hybrid inverter).
Warning

The P1 user port of the digital meter is disabled by default. Activation is done through "Mijn Fluvius". After activation online it may take several hours before the digital meter's P1 port provides measurements.

Steps to undertake:
- Check the internet connection of the Sunlight Group EMS. Check with your computer if you have internet on the ethernet cable attached to the Sunlight Group EMS.
- Try scanning on the local network for the Sunlight Group EMS with an IP scanner.
- Check with the building owner (residential) or network administrator (commercial) if this is a network with fixed IP addresses. The Sunlight Group EMS is by default configured to use DHCP. If you need to change it to a fixed IP address, first connect it to a DHCP network, and change the IP address from there to the necessary fixed IP address.
- Check if communication over the right outbound network ports is allowed.
