Sensors

All sensors from the the local API feed are available. In addition to those, there are the following computed sensors (currently only for heatpump 1):

• Textual representation of the QC supervisoryControlMode (status)
• waterDelta: difference between inlet and outlet water temperature
• heatPower: power of heat produced
• COP: realtime COP (requires power sensor)

Sensors for heatpump 2 are disabled by default. These can be enabled manually: Go to Quatt -> device -> "+6 entities not shown" -> click on a disabled sensor -> click gear -> click enable.
