Disclaimer : I am not a coder! I just started using HA (loving it) and so far the built-in cards/sensors/integrations work perfectly. However, I am now trying to optimise my solar production.
Situation : I have solar panels on 3 roofs with different orientations. I managed to add all three of them with the Forecast.Solar Integration, and the option to add them as a forecast on the Energy Dashboard appears. All good so far. What I wish to do is to combine all three “versions” so as to get one simple value that I could use in other dashboards/cards or even use in automations.
So my question is : how do I combine three solar panel datas in Forecast.Solar? It says to create a template sensor - but how? What is the yaml coding for that??
Side question : with the free version of Forecast.Solar, the forecast is not based on weather correct??
In general, template sensor Yaml will go either into your Config.yaml or if your system is set up into Template.Yaml.
This is an example of adding two sensors together. This will create a new entity you can define and then use for your frontend/automations/energy meter/etc.
And you are correct, this forecast takes in effect the location and historical forecast - but does not take in effect on current or predictive weather.
I don’t get a ton of value in the kWh totals, but I use it for the peak time of day.
