Koubachi Binding

The Koubachi Services help everybody without a green thumb to be a perfect gardener. All plants can be registered on their really nice website (or through iPhone/iPad App) to tell you when and how to care for your plants. Furthermore they offer a dedicated hardware, the WIFI Plant Sensor. This wireless device measures vital parameters and determines the vitality of your plants.

Koubachis’ slogan “give your plants a voice” becomes reality with this binding. It queries all relevant data through Koubachi’s webservice and pushes it into openHAB.


Before using the Koubachi services one has to register free of charge at Koubachi-Labs website for API access. Once the account is created the credentials and personal appKey can be obtained from the portal.

Binding Configuration

This binding can be configured in the file services/koubachi.cfg.

Property Default Required Description
refresh 900000 No The refresh interval in milliseconds. Default is 900000, the same as 15 minutes.
deviceurl https://api.koubachi.com/v2/user/smart_devices?user_credentials=%1$s&app_key=%2$s   The Koubachi API URL of the device list.
planturl https://api.koubachi.com/v2/plants?user_credentials=%1$s&app_key=%2$s   The Koubachi API URL of the plant list.
credentials   Yes The single access token configured obtained from http://labs.koubachi.com (see Prerequisites)
appkey   Yes The personal appKey obtained from http://labs.koubachi.com (see Prerequisites)

Item Configuration

In order to bind an item to a Koubachi resource query you need to provide configuration settings. The easiest way to do this is to add some binding information in your item file (in the folder configurations/items`). The syntax for the Koubachi binding configuration string is as follows:

koubachi="<device | plant>:<resourceId>:<propertyName>"

You can also bind to the action types in the Koubachi API using the keyword “action” and then the action type.


What actions can actually be performed on a specific plant depends on the type of Koubachi device used.

Here are some examples for valid item configuration strings:

To remind you to give your plant water use the following rule. First need the water level Item and some block Item to don’t spam your self.
