[OpenTRV-dev] [OpenTRV-interest] Storage heating, dynamic demand, and OpenTRV

[Bo Herrmannsen]

Oki, nice to know that i do get some points

PV is solar electric right?

But yes a heat pump can also get my vote... i just did not think of it

i could only see one downside with a heat pump, you have to adjust its use
of electricity dynamic so that the export is 0... so if you produce 1000W
it should run the heatpump up to that... if you then turn on a 500W kettle
it should adjust downwards.... can heatpumps be made to run that way?
