Solar en energy shows zero kWh

[harambe88]

Hi flixflix, I am using both of your cards. They are working perfect except for solar energy (not power) which is just zero. I have checked the value of the sensor that I use and it's no-zero. Other Sensors like grid_energy are working. Any idea what could be wrong?

I have the same Problem. I use my "Solar Energy Consumption"-Entity in the secondary info in the "home circle". It remains zero in the dashboard while the value of the entity is rising during the day.
Any hints where I can look for a solution?
