HANporten.se — a practical guide to the meter’s local interface
An open guide to Swedish electricity meters’ HAN/P1 interfaces, with protocol information and examples for reading local data.
The problem
Swedish electricity meters expose local customer interfaces with differing connectors and protocol conventions; builders need clear, usable guidance to connect their own equipment.
