Here is the controller with predictive heating using a data feed from
openweathermap.org



I still have a bit of software to write to link it all together but the foundations are there...

Looks good, guy!
How often do you have to use the oil furnace? If that's a significant #, you might benefit from some insulated hydrionic water storage to heat from the solar and/or heat pumps and tie it to your predictive software.
Maybe a link to your code when you finish?

Almost never. This year I guess no more than a couple of days in total. I guess we used maybe 15 litres of oil but maybe less. The boiler only comes on when the hps (I have 2 running) can't cope and that is pretty rare.

As it's pretty close to switch off time I'll publish this years data in another post. There I keep a running update of performance.

Default SolarQuant

We are building out a module of our open-source platform which is called SolarQuant which has this idea in mind of providing advice only to a system that could do optimum switching.

the idea is that this module will sit and watch both consumption/generation/weather/weather forecasts and aim to provide energy forecasts for systems that need advice in what switches should be thrown. it would only provide the advice, you could do your own switching, but we have a local device called a SolarNode (can run on a raspberry pi) than also could do the switching.

but since everything is going to use RESTful web services it's going to be pretty ready for integration with lots of stuff.
