This app ONLY works with MODBUS enable LG devices, these are normally the AWHP pro installer devices. Commercial devices are more likely to use only LG Thinq (ook at the apps that support those). With these modbus devices the modbus tends to have more data than any Thinq support does. And its fully local. It also allows for more live data.
Monitor and control your LG Air-to-Water Heat Pump directly from Homey — no cloud, no delays. This app communicates locally over Modbus TCP through an RS485-to-TCP gateway, giving you fast, reliable access to your heat pump’s data and controls.
What you can do:
- Switch heating/cooling on or off and set operation mode (Heat, Cool, Auto)
- Adjust water target temperature and DHW (hot water) target temperature
- Monitor live temperatures: water outlet, water inlet, outdoor, room, DHW tank, and backup heater
- Track energy usage: electrical power consumption, thermal output, and real-time COP
- View system status: compressor, water pump, defrost cycle, and outdoor unit activity
- Control DHW heating, silent mode, and temperature control method
- Get notified on errors with automatic alarm detection and error codes
- Build automations with flow triggers, conditions, and actions for all key parameters
Requirements:
- LG Air-to-Water Heat Pump with Modbus RTU support
- RS485-to-TCP serial gateway (like Elfin EW-11 or compatible) connected to the heat pump’s Modbus port
- Homey Pro with local network access to the gateway
