Bug description or desired functionality.

Would be awesome to see a prediction how long the battery power will last. This can either be simple by alwas taking the current consumtion into account or a bit smater by also takink the historical consumption into account. Even smarter ;-) would be to include the predicted solar power of the the next hours/days.
The simple implementation would be a great start.

Hi. We (FENECON) do not currently plan to implement this. Techically the feature would be similar to what is already implemented for the Grid-Optimized-Charge-Controller. The Controller uses predictions for Consumption and Production and visualizes the planned State-of-Charge of the battery:
