Thanks a lot! I learned something new today 
. Iused the VD from Arie J. Godschalk, great app.
I created two Solar Panel virtual devices, and they are both correctly identified. Everything is working fine now! You were right—solar production should be positive, not negative! I’ve send an email to Homey Support on this.
My solar system is EcoFlow, but PowerStream is not (yet) supported. To work around this, I’m using Home Assistant, which has excellent integration for solar products. I then use Virtual Devices to send the data from HA to the Energy Dashboard.
Hopefully, EcoFlow PowerStream will be supported soon!
