Smart Air Conditioner


Recommended Posts

Are there any air conditioners available here which can manage their power usage according to the amount of Solar PV available ? ie read existing Energy meter ( SMA ) and adjust output accordingly to maximise solar PV usage?

@NoordSolar You could automate it with Node Red using information it gets from the inverter, is pretty easy to do as long as you don't mind spending a few hours watching Youtube video's.

My Node Red cycles through my heavy loads based on a SOC, current Solar PV production from the inverter and from the smart breaker switches (current load on the breaker when switched on) that send power to the heavy loads i.e. geysers/Borehole/Pool etc. When one geyser is up to temp the load on it drops and it can cycle to the next load. 

I also decide whether to switch the pool on in the morning based on solar weather forecast for the day in Home Assistant.

As long as the Aircon interfaces with Node Red/Home Assistant it would not be an issue.

There seem to be a few options as to how to do this
