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.
Adding IoTaWatt to your Home Assistant instance can be done via the user interface, by using this My button:
If the above My button doesn’t work, you can also perform the following steps manually:
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, following these instructions:
You will need to configure two new IoTaWatt output sensors:
(Main_In_Red + Main_In_White + Main_In_Blue) with the correct formula for your main feed.
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
(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
Solar2 you would use:
(Main_In_Red + Main_In_White + Main_In_Blue - Solar1 - Solar2)
