integration |
Integration for the IoTaWatt Open WiFi Electricity Monitor. It will collect data from the Current Transformer Clamps (Input CTs) and any Outputs that are defined on the IoTaWatt and create them as sensors in Home Assistant.

Energy management
You can use the accumulated energy sensors directly with the Home Assistant energy dashboard.
If you have an energy production system such as solar panels, follow these instructions:
Configure IoTaWatt
You will need to configure two new IoTaWatt output sensors:
| Name | Unit | Formula |
|---|---|---|
| MainsConsumption | Watts | (Main_In_Red + Main_In_White + Main_In_Blue) max 0 |
| MainsExport | Watts | ((Main_In_Red + Main_In_White + Main_In_Blue) min 0) abs |
Replace (Main_In_Red + Main_In_White + Main_In_Blue) with the correct formula for your main feed.
Using a solar net system
The IoTaWatt team recommends that the inputs for solar reads positive which can be achieved by either changing the orientation of the CT sensor or in the IoTaWatt's input settings, check Reverse.
Replace (Main_In_Red + Main_In_White + Main_In_Blue) with (Main_In_Red + Main_In_White + Main_In_Blue - Solar)
If you have two solar sensors named Solar1 and Solar2 you would use:
(Main_In_Red + Main_In_White + Main_In_Blue - Solar1 - Solar2)
Configure Energy Management
In the Grid Consumption settings, click Add Consumption and select MainsConsumption.wh Accumulated
In the Return to grid settings, click Add Return and select MainsExport.wh Accumulated
In the Solar production settings, click Add Solar Production and select Solar.wh Accumulated
