Activation of the P1 port
All our new meters have a P1 port (HAN port). This port enables, for example, load balancing for chargers and the use of other home automation solutions that depend on the household’s electricity consumption/production.
Frequently Asked Questions about the P1 port
Yes, once the port has been activated. The device connected to the port is purchased and installed by the customer.
You will receive a confirmation from us by text message when the activation has been completed, and the P1 port will start transmitting data immediately after activation. You can also check the status of the P1 port activation in the MyHerrfors service.

Change of fuse size for the point of use
The fuse size of the supply point determines how much electricity can be used simultaneously — but the change is always made within the limits of the existing electricity connection’s capacity.
Frequently Asked Questions about changing the fuse size of the supply point
No, you cannot. The change must always be carried out by an authorized electrical contractor. They ensure safety and make the necessary notifications.
We do not charge for the change if it stays within the limits of the existing connection and does not require meter modifications. Your own electrical contractor will invoice the work separately.
