In order to save energy it helps to know your consumption. To do this you can use Energy Meters to track the consumption of all connections in your distribution board. In this project seven 1-phase energy meters and three 3-phase energy meters are used to cover the complete distribution board. The Energy Meters are connected in series with the automatic fuses by an certified electrician.
Its been verified to work with a Raspberry Pi 3 with a Linksprite RS485 shield and reading values from a SDM120 and SDM630. By changing the meters.yml file and making a corresponding [model].yml file it should be possible to use other modbus enabled models.
