Have been looking for in the US a ductless mini split heat pump system something like the Mitsubishi Electric Mr. Slim that uses a non proprietary wiring scheme for its wall mounted thermostats. Ideally it would be the standard 24VAC wiring scheme something like (R,G,W,Y,C) that would allow the system to be controlled by a internet connected thermostat such as the Nest, EcoBee, etc...
Most of the ductless mini split systems I have observed come with either fairly complex non internet connected programmable wall thermostat or come with a dumb to complex remote control to mange its operation.
Does anyone know of any ductless systems that offer standardized HVAC controls, remote internet management or other smart home automation capabilities?
