since days I try to feed my Homey with values that enable Energy Tab Visualization.
I can handle virtual machines, mod bus request and extended flows to feed variables with values.
BUT: I still don’t get it which values / variables / configuration is needed to feed exact the values that enable the visualization in the Energy Tab AND enable energy management.
Can someone bring light into this? Every support or instruction is welcome (Did several WEB researches w/o success).
I´m using an Fenecon Home System (Solar, Battery and Goodwe Inverter). The Fenecon System offers a ModBus Interface that supports all values that are needed. The Modbus Interface is not the same like Goodwe, so using the GoodWe App for Homey does not help.
All necessary information can be found in the following section of the Homey Apps SDK:
So you need virtual devices in which the values of your devices are written and which also meet the requirements of the document.
For PV modules or inverters, you can create an Advanced Virtual Device using the Device Capabilities app, f.e. Batteries are currently not supported by the DC app or an AVD, as the necessary capabilities may still be missing.
Information about how to create an AVD in general, can be found in this topic → [APP][Pro] Advanced Virtual Device (Device Capabilities App) with Unique Text Status Indicator
I’ve created a tutorial on how to write the data from a micro inverter and an OpenDTU to an AVD, whose values are then displayed in the Homey Energy Dashboard.
In the following chapter, I explain how to create and configure the AVD → Advanced Virtual Device
And in this chapter, I explain how to write the incoming data to the AVD via Flow → Flow
