Waterkotte EcoTouch Heat Pump Binding - vpjuslin/openhab GitHub Wiki

Documentation of the Waterkotte EcoTouch heat pump binding bundle.

Introduction

For installation of the binding, please see Wiki page Bindings.

Precondition

This bundle connects to your heat pump via network. Make sure the display unit of your heat pump is connected to your network and that the network settings are configured. By default, the heat pump uses DHCP.

Generic Item Binding Configuration

The binding configurations format is simple and looks like this:

ecotouch="<eventType>"

where eventType is one of the following values:

  • temperature_outside
  • temperature_outside_1h
  • temperature_outside_24h
  • temperature_source_in
  • temperature_source_out
  • temperature_return_set
  • temperature_return
  • temperature_flow
  • temperature_room
  • temperature_room_1h
  • temperature_water
  • temperature_pool
  • temperature_solar
  • temperature_solar_flow
  • power_compressor
  • power_heating
  • power_cooling
  • cop_heating
  • cop_cooling
  • temperature_heating_return
  • temperature_heating_set
  • temperature_cooling_return
  • temperature_cooling_set
  • temperature_water_set
  • temperature_pool_set
  • compressor_power
  • state_sourcepump
  • state_heatingpump
  • state_evd
  • state_compressor1
  • state_compressor2
  • state_extheater
  • state_alarm
  • state_cooling
  • state_water
  • state_pool
  • state_solar
  • state_cooling4way

Not so common ones:

  • temperature_heating_set2
  • temperature_cooling_set2
  • temperature_pool_set2
  • temperature_water_set2
  • state
  • temperature_evaporation
  • temperature_suction
  • pressure_evaporation
  • temperature_condensation
  • pressure_condensation
  • temperature_storage
  • position_expansion_valve

As a result, your lines in the items file might look like the following:
