Home Energy Monitor

This live data feed is produced by my EmonPi home energy monitor and updated every 60 seconds. My home electricity system is comprised of a 3995 Watt grid connected solar system, a 4800 Watt grid connected electricity storage battery, solar electrical water heating system and a connection to the National Grid electricity supply. All this equipment is monitored using current transformers connected to the EmonPi energy monitor. A minus “Import/Export” value is surplus electricity exported to the National Grid. A positive “Import/Export” value is power imported (purchased) from the National Grid. The imported electricity between 00:30 hours and 04:30 hours is purchased on a cheap rate tariff. This cheap rate electricity is used to charge the battery as required thus minimising the import of electricity from the grid and maximising the use of free electricity provided by the solar panels.
