# EcoTouch Binding
The openHAB EcoTouch binding allows interaction with a Waterkotte (opens new window) heat pump.
# Supported Things
| Thing type | Description |
|---|---|
| geo | Waterkotte EcoTouch Geo + EcoVent |
| air | Waterkotte EcoTouch Air + EcoVent |
This binding was tested with a Waterkotte DS 5027 Ai DS 5010.5Ai geothermal heat pump.
# Discovery
Discovery is not supported. You need to provide the IP address of the display unit of the heatpump.
# Thing Configuration
Things can be fully configured via the UI. The following information is useful when configuring things via thing configuration files.
| Property | Type | Default | Required | Description |
|---|---|---|---|---|
| ip | String | yes | IP address or hostname of the display unit of the heat pump | |
| username | String | yes | since software version 1.6.xx of the display unit: "waterkotte"; previously "admin". | |
| password | String | yes | since software version 1.6.xx of the display unit: "waterkotte"; previously "wtkadmin". | |
| refresh | Integer | 60 | no | time in s after which all channels will be requested again from the heat pump |
