"Capacity: Next Dawn" sensor?

It'd be really useful if there was a sensor that predicted the battery capacity at the next dawn time. Exactly the same concept as the “Capacity: Eco Start” sensor.

That way, I know how much battery “budget” I have. For example, if the prediction is 4 kWh at next dawn time, I can spend 2 kWh on my air conditioning, before hitting my 2 kWh minimum and drawing from the grid.

Fairly self-explanatory I hope. If not, please ping me with any questions. Thanks!

@andrewmooreio this is a great idea, almost to 'front load' the solar - i.e. if capacity @ dawn > 0 & export > 0 then switch on the immersion heater (or AC). I'd also benefit from this as although the 3.7 inverter is limited on AC it can charge the batteries at much higher DC so it makes sense to go into a high solar day with limited SoC having heated the hot water etc.

I'll have a think where best to put it, as in the winter months it should always just read as the dawn buffer. 👍

Thanks. Yeah, it's definitely only a summer thing really. At least for those of us in the UK! At the moment my home battery, car, and water tank are all full by midday most of the time. So it's good to know how much extra I can divert to other devices.
