I have a suite of LG Minisplits installed in my apartment. While there isn't a distinctly open API, there's an integration that you can add to Home Assistant for access to the platform.
From there, I've got a few automations including:
- Automatically turning off "conflicting" units (Heat vs Cool)
- Schedules (set bedroom to cool at night) and "Away" modes
- Temperature overrides using custom built temperature sensors (BME280 to the rescue)
- Access and control via voice (via Google Assistants)
Unfortunately, the integration is reliant on the cloud, but you can connect a "traditional" relay based thermostat to them as well (with the loss of variable load control for the outside unit).
