I’ve had my emonPi and Solar install for about 18 months now… very happy.
We currently have no PV battery, no immersion/header tank as both central heating and DHW are through the 3 year old combi-boiler.
So to this point i’ve not really had to worry about any scheduling of large electricity draw items.
Moving to Agile has changed the mindset a little, avoiding washing, tumble drier etc between 4pm and 7pm… but its all manual and we try to use the Solar where we can for those bigger bits.
But now, we are contemplating an EV.
It seems like the majority of EV chargers are either good at being hooked up to a house with Solar (like a Zappi)… or being developed with API and TOU tariffs in mind (Ohme Charger).
I can’t seem to find an EV charger than can do BOTH?
Is this where OpenEVSE and Demand Shaper fills the gap?
Ideally you want a simple tick list / set of rules like.
Is there excess Solar generation - yes, that always takes priority
Is Car battery below 50% AND Agile pricing below 3p - yes
Or something like that.
Does that make sense?
