:warning: Starting from version 1.0.0b5: You might probably have to uninstall and reinstall the integration as credentials requirements and method has changed. THERE IS A BREAKING CHANGE IN THE CONFIGURATION DUE TO AN UPDATE ON THE GARDENA API

About

This component is originally based on https://github.com/grm/home-assistant/tree/feature/smart_gardena and https://github.com/grm/py-smart-gardena

The integration / component has been changed quite a lot, mainly to add support for config flow setup and Home Assistant devices. It has also been cleaned up and some bugs have been fixed. Gardena devices are now represented as Home Assistant devices, which have battery level sensors where applicable.

This project needs your support.
Gardena equipments are expensive, and I need to buy them in order to add support. If you find this library useful and want to help me support more devices (or if you just want to reward me for my spent time), you are very welcome !
Your help is very much appreciated.

Here are the links if you want to show your support :

Installation

Requires Home Assistant 0.115.0 or newer.

Installation through HACS

If you have not yet installed HACS, go get it at https://hacs.xyz/ and walk through the installation and configuration.

Then find the Gardena Smart System integration in HACS and install it.

Restart Home Assistant!

Install the new integration through Configuration -> Integrations in HA (see below).

Manual installation

Copy the sub-path /hass-gardena-smart-system/custom_components/gardena_smart_system of this repo into the path /config/custom_components/gardena_smart_system of your HA installation.

Alternatively use the following commands within an SSH shell into your HA system.
Do NOT try to execute these commands directly your PC on a mounted HA file system. The resulting symlink would be broken for the HA file system.

cd /config
git clone https://github.com/py-smart-gardena/hass-gardena-smart-system.git

# if folder custom_components does not yet exist:
mkdir custom_components

cd custom_components
ln -s ../hass-gardena-smart-system/custom_components/gardena_smart_system

Configuration

Home Assistant

Setup under Integrations in Home Assistant, search for "Gardena Smart System". You need to enter your application key / client ID and your applications secret / client secret. See below for how to get your Gardena application key and secret.

After setting up the integration, you can adjust some options on the integration panel for it.

Even though this integration can be installed and configured via the Home Assistant GUI (uses config flow), you might have to restart Home Assistant to get it working.

Gardena Application Key / Client ID and Application secret / client secret

In order to use this integration you must get a client ID / Application Key from Gardena/Husqvarna.

1. Go to https://developer.husqvarnagroup.cloud/

2. Create an account if needed, otherwise sign in with your Gardena account.

3. After signing in you will be automatically redirected to "Your applications". (Otherwise go to: https://developer.husqvarnagroup.cloud/applications)

4. Create an new application, name it for example "My Home Assistant" (doesn't matter), leave the other fields empty.

5. Click on "+Connect new API" and connect the Authentication API and the GARDENA smart system API.

6. Copy your Application Key and Application secret, this is what you need when you add the integration in Home Assistant.

Supported devices

The following devices are supported :

• Gardena Smart Irrigation Control (as switch)
• Gardena Smart Mower (as vacuum)
• Gardena Smart Sensor (as sensor)
• Gardena Smart Water Control (as switch)
• Gardena Smart Power Socket (as switch)

Services

Smart Irrigation Control services

[TODO: document services]

Smart Mower services

vacuum.start
Start the mower using the Gardena API command START_SECONDS_TO_OVERRIDE.
The mower switches to manual operation for a defined duration of time. The duration is taken from the integration option "Mower Duration (minutes)" (see Configuration -> Integrations in HA).

vacuum.stop
Stop the mower using the Gardena API command PARK_UNTIL_FURTHER_NOTICE.
The mower cancels the current operation, returns to charging station and ignores schedule.

vacuum.return_to_base
Stop the mower using Gardena API command PARK_UNTIL_NEXT_TASK.
The mower cancels the current operation and returns to charging station. It will reactivate with the next schedule.

Smart System general

binary_sensor.gardena_smart_system_connection Checks if service is connected or disconnected

Smart Power Socket services

[TODO: document services]

Smart Sensor services

sensor.sensor_light_intensity Read the light intensity of a smart sensor. Only V1 of the Smart Sensor supports this.

sensor.sensor_soil_humidity Read the soil humidity of a smart sensor. This can help automate your Water control / Irrigation Controller.

sensor.sensor_soil_temperature Read the soil tempature.

sensor.sensor_ambient_temperature Read the ambient tempature of a smart sensor.

sensor.sensor_battery_level Read the battery level of a smart sensor.

Smart Water Control services

[TODO: document services]

Smart Irigation Control services

switch.irrigation_control_valve_X Open or close a valve to start watering . Irrigation control can have up to 6 valves and inherits the original name of each valve from the Gardena app. If a valve is not connected, the service for the specific valve is unavailable.

Recipes

Some recips were made by the community. You can find them here.

Development

Debugging

To enable debug logging for this integration and related libraries you can control this in your Home Assistant configuration.yaml file. Example:

logger:
  default: info
  logs:
    custom_components.gardena_smart_system: debug
    custom_components.gardena_smart_system.mower : debug
    custom_components.gardena_smart_system.sensor : debug
    custom_components.gardena_smart_system.switch : debug
    custom_components.gardena_smart_system.config_flow : debug

    gardena: debug
    gardena.smart_system: debug
    websocket: debug

After a restart detailed log entries will appear in /config/home-assistant.log.

TODO

• Do we need support for more than one location? Should we make it possible to configure it?
