Huawei Solar PV

Quick app that reads values ​​from your Huawei Solar. If you have a battery, you can adjust working modes and force charging/discharging. It is also possible to trigger one of these modes via a scene. Unfortunately, Fibaro has limitations in block scenes when using sliders (only 0-100). If sliders are to be used with higher values, the scene must be converted to LUA.

 

Depending on the battery/batteries, a different number of "child units" are displayed. The "child" which by default shows the Grid frequency can easily be adapted to a different value by changing it in the variable tab. In the documentation that you find here, you can select which numerical value should be displayed instead of Grid frequency. You change the variable childSignalName, childUnit, childGain, childAddress and childQuantity as desired according to the documentation.

The requirement to be able to use this is that someone with installer rights change the FusionSolar web interface (Device management -> Set Parameters (Dongle) -> ModBus-TCP) to Enable (unrestricted) or Enable (restricted) along with the IP address of your Home Center.
