Use forecast.solar HA integration entities

Open w4iq3 opened this issue 6 months ago • 7 comments

Can the entities provided by the forecast.solar integration directly be used by batpred, same as with the Solcast option?

Don't believe so. Predbat is designed to be used with Solcast, and any tests I have seen always come out that Solcast gives a more accurate forecast than forecast.solar

Solcast only supports 2 orientations in the free version, I have more so I was wondering if this could be added.

Just a thought, but perhaps if it were somehow possible to support both simultaneously, as a result of an enhancement, you could use solcast for the two biggest arrays, and forecast.solar for the smaller arrays.

Currently I believe the advice from Solcast is that you can average two arrays together (so if you had 8 panels facing south-southwest, 30 degrees, and 12 panels facing west-northwest 20 degrees, you could model it as 18 panels facing west, at 24 degrees).

There is a mention of Forecast.solar in the docs.

But it would be nice to be able to use the entities already in HA from the module as like the OP I have more than 2 orientations and find the calculation by solcast to be questionable more than a lot of the time (trying to average the direction of the panels) where as forecast.solar is far more reliable.

The docs describe how to configure predbat to call to forecast.solar to get your solar forecast https://springfall2008.github.io/batpred/apps-yaml/#forecastsolar-solar-forecast

You can add multiple arrays if need be.

This is Predbat directly calling forecast.solar, not using a HA integration. It should give you what you need

My mistake on the above comment, predbat can now call to forecast.solar

It would be nice if we could still use the existing forecast.solar module that HA has (which is already used on the Energy page). If the data is already there, would be silly to duplicate those calls?
