Just set #HomeAssistant (#MelCloud integration) to always generate heat in the heat pump water cylinder instead of exporting excess #electrical #energy to the #grid.

I'm up to using about 20Kw(and battery storage) now to avoid feeding back into the grid..

Usage breakdown:
* #Heatpump / Water (10k)
* #ev (3k)
* #Dehumidifiers (3k)
* #HotTub (4k)

I want the grid to be full of #green energy but at the price point they are willing to pay me it's more cost effective to use it locally.

I've created another 'useless' #homeassistant automation: Now I receive a notification when a heat pump defrosts.

How?
#MELcloud integration doesn't provide any defrost info, but I can read the temperature sensor which is just above the heat exchanger coil.

I've created a new virtual sensor in #ha configuration.yaml, which calculates a temperature trend over the last 5 minutes. If the temp. change is greater than 1,5 degree (a spike), this means the coil was heated and defrosted.

She: He must be thinking of other women...
He: If I connect #homeassistant to some sensors via #MELcloud, I could remotely view what's happening in the boiler room...
