An adapter for GARDENA smart system using official GARDENA smart system API and service.

The adapter allows the development of an application (e.g. with VIS) that can be used in parallel with the official GARDENA app. The adapter and its additional features do not affect any of the basic functions of the GARDENA app and vice versa.

The adapter is not a complete replacement for the GARDENA app, but an addition to integrate the GARDENA devices into a smart home with ioBroker. The most important actions can be carried out with the adapter. It also offers the opportunity to implement your own ideas that are not possible with the GARDENA app.

• GARDENA smart SILENO robotic lawnmowers
• GARDENA smart Irrigation Control
• GARDENA smart Pressure Pump
• GARDENA smart Water Control
• GARDENA smart Power Adapter
• GARDENA smart Sensor

For more information about the devices see at GARDENA German website and here in English.

To use this adapter you need the following things:

1. an GARDENA smart system account
2. an GARDENA application key
3. an GARDENA application secret

To get those things please go to Husqvarna Developer Portal at https://developer.husqvarnagroup.cloud/.

Please Sign up or Log in if you already have an account and create a new application to get your application key and application secret.

Currently the site looks like in the following screenshots.

Press button NEW APPLICATION

Edit form with your own data. Currently the field Redirect URLs is not used. That's why you can currently enter any value. Press button CREATE

At the next page you get the application key and application secret. You will need those values for your adapter instance configuration. And you have to connect the APIs

• Authentication API and
• GARDENA smart system API.

For this press button CONNECT NEW API and select the first API. And repeat for the second API.

Note:

• If you already have a Husqvarna Automower® Connect or a GARDENA smart system account, you can Sign In with that account and continue with Create application to get the application key and application secret.

  ---

  And it's almost certain that you have an account. Please use the same account as for the GARDENA app in which your GARDENA devices are registered. Otherwise you will not get access to your devices.

  ---

• Make sure that you've connected the application to the API's

  • Authentication API and
  • GARDENA smart system API.

And of course you need a running ioBroker installation (at least using admin5 UI) and you should own at least one working GARDENA smart device.

Adapter is available

• at npm: Install with npm install iobroker.smartgarden
• at GitHub under https://github.com/jpgorganizer/ioBroker.smartgarden. An description how to install from GitHub is available here (German language).

1. Install the adapter

2. Create an instance of the adapter

3. Check and complete instance configuration

   If you change any value of those settings please restart your adapter.

   3.1 Edit application key and application secret and/or optional username, password in main instance configuration

   Parameter	Description
   mandatory
   Application key	Application key (API key), e.g. under Requirements
   either application secret or username and password *) **)
   recommended
   Application secret *)	application secret, e.g. under Requirements - only if username and password are empty (new in v2.0.0)*
   not recommended
   username *) **)	username for GARDENA smart system - only if application secret is empty
   password *) **)	corresponding password - only if username is specified

   NOTES:
   *)

   • From release v2.0.0 the preferred login procedure is using application key and application secret as the former login procedure with username and password isn't supported by Gardena anymore, but nevertheless it's still working for many users. For this reason it is still available here, but in the event of an error, there is no longer any support for it. So it's recommended to use application key and applicaton secret!

   • Application key, application secret and password are encrypted and stored within the adapter and become just decrypted for authentication with the GARDENA application host.

   **)

   • parameter is discontinued and may no longer be available in a future version

   3.2 Verify default values of miscellaneous settings and switch on/off options in instance configuration. For most users the default values will be ok.

The adapter is designed to monitor and control GARDENA smart system devices. For this there will be one LOCATION and one or many DEVICE's. For each DEVICE there will be

• one SERVICE_COMMON_<id> and
• one or more SERVICE_<servicelink_type>_<id>.

Where <servicelink_type> is a type description for the device, for example MOWER or VALVE and <id> is a (encoded) GARDENA device id used by the API. See description for ServiceLink at https://developer.husqvarnagroup.cloud/apis/GARDENA+smart+system+API#/swagger.

Controlling/monitoring for each device is possible via the SERVICE_<servicelink_type> listed in the following table. The SERVICE_COMMON provides general information about the device.

If you need more information about the data points please have a look at https://developer.husqvarnagroup.cloud/apis/GARDENA+smart+system+API#/swagger. There you'll find a description for every data point; except for those which are marked as data points of the adapter and not of the GARDENA smart system API.

The adapter creates its own data points for various features / options when the feature is selected. These data points are not automatically deleted when the feature is deselected. If you no longer need these data points, they can be deleted manually.

The adapter doesn't change any values transmitted by the GARDENA smart system API. The only thing that is done (from version 1.0.0) is to check the type of timestamps and numbers.

Requests to control a device will succeed as soon as the command was accepted by the smart Gateway. A successful execution of the command on the device itself can be observed by a respective state change. Example: sending a command to start the VALVE service of a smart Water Control will result in the activity_value data point of the service to be changed after the device processed the command.

Notes:

• Requests to control a device cannot be sent while the smartgarden adapter is not connected to GARDENA smart system API.
• Please check that you set the value for a command with ack=false. See Chapter Commands and Statuses in Guide for adapter developers

To control the device use data point

• activity_control_i: type string

  This data point is generated by the adapter and is not required due to the GARDENA smart system API.

  Change this data point to start the mower.

  • To start for a defined time set the value to the planned duration in seconds (please use multiples of 60; minimum is 60); consider the data type string
  • for automatic operation set string START_DONT_OVERRIDE
  • to cancel the current operation and return to charging station use string PARK_UNTIL_NEXT_TASK
  • to cancel the current operation, return to charging station and ignore schedule use string PARK_UNTIL_FURTHER_NOTICE

  Note: The mower only starts with a fully charged battery.

All other data points are just for monitoring and information.

Special data points:

• activity_mowing_i

  This data point is generated by the adapter and is not required due to the GARDENA smart system API.

  This data point shows two different states for the mower:

  • true: mowing or
  • false: not mowing.

  This data point can be used for further actions where it is important to know whether the mower is safely on the lawn or not.

  Depending on the value of data point activity_value this data point is set. Please see following table for details.

  activity_value	activity_mowing_i
  OK_CHARGING The mower has to be mowing but insufficient charge level keeps it in the charging station.	false
  PARKED_TIMER The mower is parked according to timer, will start again at configured time.	false
  PARKED_PARK_SELECTED The mower is parked until further notice.	false
  PARKED_AUTOTIMER The mower skips mowing because of insufficient grass height.	false
  PAUSED The mower is in a waiting state with hatch closed.	false
  OK_CUTTING The mower is cutting in AUTO mode (schedule).	true
  OK_CUTTING_TIMER_OVERRIDDEN The mower is cutting outside schedule.	true
  OK_SEARCHING The mower is searching for the charging station.	true
  OK_LEAVING The mower is leaving charging station.	true
  NONE No activity is happening, perhaps due to an error.	true
  all other values	true

• batteryState_chargingTime_remain_i (under SERVICE_COMMON...) and
  activity_mowingTime_remain_i (under SERVICE_MOWER...)

  Both data points are generated by the adapter and are not required due to the GARDENA smart system API.

  Those data points show an forecast for remaining charging and mowing time in seconds of the mower. They are only created when the function is selected in the instance configuration.

  To forecast a value an history of the last few charging and mowing cycles is saved in two states info.saveMowingHistory and info.saveChargingHistory.

  This feature can be switched on/off in adapter instance configuration along with the number of saved charging and mowing cycles in history.

  To put this function into operation, please make sure that at least one cycle of mowing and charging runs without errors (e.g. not interrupted manually or sensor control). It is better if at least three runs are completed without errors. This function tries to recognize the normal case and initially assumes that the next process is a normal case. If this is faulty, then this faulty run is regarded as a normal case and the runs that then pass through normally as a fault case. If there is an error during the run, please stop the adapter, delete the two data points and start again.

  For more information about general forecasting mechanisms see FORECAST.md.

  Notes:

  1. Forecast values are only available if at least one complete charging and mowing cycle is saved in history.

  2. The history is saved under info so that if the LOCATION needs to be deleted, e.g. in the event of a future update, it is not lost.

  3. If you disconnect your mower from the GARDENA smart system and reconnect it again the history is lost, because your mower get's a new id within the GARDENA smart system. This means that the adapter cannot recognize the mower as the previous mower - may be it's a second one. In this case it is recommended to delete these two data points and to restart the adapter so that the previous (now old) history sets are not constantly read and written. The adapter then begins to build a new history.

  4. This function should work for more than one mower, but it is not tested (I can't do that, because I've only one mower). If you have more than one mower please test and report errors and of course report if it works as intended. Thanks in advance for that.

• lastErrorCode_value

  Please pay special attention to data point lastErrorCode_value. A description of possible values can be found at https://developer.husqvarnagroup.cloud/apis/GARDENA+smart+system+API#/swagger, see "MowerService - lastErrorCode"

To control the device use data point

• stop_all_valves_i: type string

  This data point is generated by the adapter and is not required due to the GARDENA smart system API.

  Change this data point to stop all valves.

  • To stop all valves immediately use string STOP_UNTIL_NEXT_TASK

  Note: Do not display the value of this data point in your application, as the value is mostly undefined. Furthermore, this data point cannot serve as a trigger for your own actions, because it is just set to value null after the command was triggered.

All other data points are just for monitoring and information.

To control the device use data point

• duration_value: type string

  Change this data point to start the valve.

  • To start for a defined time set the value to the value in seconds (please use multiples of 60; minimum is 60); consider the data type string.

    Note: There are some limitations for the allowed values. Please report if you see other limitations.

    device	limit
    GARDENA smart Irrigation Control	5400 seconds (90 minutes)
    GARDENA smart Pump	36000 (10 hours)
    GARDENA smart Water Control	36000 (10 hours)

  • To cancel the current watering and continue with the schedule use string STOP_UNTIL_NEXT_TASK

  • To skip automatic operation until specified time, the currently active operation might or might not be cancelled (depends on device model) use string PAUSE_<number_of_seconds>, e.g. PAUSE_86400 to pause for 24 hours (please use multiples of 60; minimum is 60)

  • To restore automatic operation if it was paused use string UNPAUSE

• irrigationWhileMowing_allowed_i and irrigationWhileMowing_mowerDefinition_i

  This data points are generated by the adapter and are not required due to the GARDENA smart system API.

  Those data points give control over the feature Irrigation not allowed while mowing. They are only created when the function is selected in the instance configuration. For description of this feature see chapter Irrigation not allowed while mowing.

All other data points are just for monitoring and information.

Special data point:

• duration_leftover_i

  This data point is generated by the adapter and is not required due to the GARDENA smart system API.

  The value describes the number of minutes till the valve is closed and watering stops.

  • An integer, one (1) or more.
  • null if undefined

To control the device use data point

• duration_value: type string

  Change this data point to start the power socket.

  • To start for a defined time set the value to the value in seconds (please use multiples of 60; minimum is 60); consider the data type string
  • To switch on the device forever please use the string START_OVERRIDE.
  • To stop the device use STOP_UNTIL_NEXT_TASK.
  • To skip automatic operation until specified time. The currently active operation will NOT be cancelled. Use string PAUSE_<number_of_seconds>, e.g. PAUSE_86400 to pause for 24 hours (please use multiples of 60; minimum is 60)
  • To restore automatic operation if it was paused use string UNPAUSE

All other data points are just for monitoring and information.

Special data point:

• duration_leftover_i

  This data point is generated by the adapter and is not required due to the GARDENA smart system API.

  The value describes the number of minutes till the power socket is shut off.

  • An integer, one (1) or more.
  • null if undefined

No control functions available.

All data points are just for monitoring and information.

The SERVICE_COMMON provides general information about the device. Description is integrated into description of other SERVICE_... where necessary.

There are some limits you shoud be aware of. Please see chapter Rate Limits in README of GARDENA smart system API description.

To help you to see if you hit those rate limits you can switch on monitoring in instance configuration with parameter monitoring Rate Limits.

If you've enabled monitoring state info.RateLimitCounter gets actualized with every request. This state saves a data structure with the number of requests per month, day, hour and for the last 30 and 31 days.

The structure is in JSON and looks like

{
  "2020": {                          <<< year
    "2020-08": {                     <<< month
      "count": 21,                   <<< number of requests for month
      "2020-08-27": {                <<< day
        "11": {                      <<< hour
          "count": 3                 <<< number of requests for hour
        },
        "12": {                      <<< hour   
          "count": 13                <<< number of requests for hour
        },
        "count": 16                  <<< number of requests for day
      },
      "2020-08-28": {                <<< day
        "14": {                      <<< hour
          "count": 5                 <<< number of requests for hour 
        },
        "count": 5                   <<< number of requests for day
      }
    }
  },
     ...
  "last30days": {                     
    "count": 2021                    <<< number of requests in last 30 days
  },
  "last31days": {
    "count": 2098                    <<< number of requests in last 31 days
  }
}

Note:

• That hour is hour of time in UTC
• That the actual number of requests may be higher. Especially as long as the respective period is not fully covered by the monitoring.
• That this structure becomes very large and is never deleted by the adapter. So please delete it manually from time to time or switch off monitoring - at least if you don't have any issues with the rate limits.

If you have both a mower and an irrigation system with pop-up sprinklers, there is a risk that your mower will run into a pop-up sprinkler while the irrigation is running and damage it or cause damage itself.

To prevent this, the irrigation system or better individual valves should be switched off when the mower is mowing.

With this function it is possible to stop irrigation when the mower is on the lawn. This can be defined separately for each valve.

One or more mowers can be defined for each valve, for which the valve is not allowed to be open while the mower is mowing. Basically, the mower has priority over irrigation, i.e. if the conflict arises that the mower is mowing and a valve is open, the valve is closed and a corresponding warning is set.

Additionally it is possible to define that a valve should never open regardless of a mower. E.g. can be used if a valve or the pipe behind it is damaged.

The whole check can be switched on or off in instance configuration with parameter irrigation check.

There are three data points available for each SERVICE_VALVE. They are used for configuration and for reporting warnings.

• mower id format

  smartgarden.0.LOCATION_xxxxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxxxxxxxxxx.DEVICE_xxxxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxxxxxxxxxx.SERVICE_MOWER_xxxxxxxx-xxxxxx-xxxxxx-xxxxxxxxxxxxxxxxxxxxx

  You can copy this mower id from the objects tab of ioBroker, see red arrow in the following picture.

  

• warning codes

  warning code	description
  NO_WARNING	no warning, valve opened
  UNKNOWN_MOWER	wrong mower id in irrigationWhileMowing_mowerDefinition_i
  STOPPED	valve automatically closed because mower is mowing
  FORBIDDEN	valve closed because special code IRRIGATION_FORBIDDEN is set in data point irrigationWhileMowing_mowerDefinition_i

This function is runnig every time when

• a valve becomes opened or
• a mower starts mowing

It doesn't run when you change the values in the data points listed above. That means: if there is a conflict situation and you change irrigationWhileMowing_allowed_i from true to false, the conflict is not recognized and the conflict will continue. The same behaviour applies to a change of irrigationWhileMowing_mowerDefinition_i.

This feature cannot prevent a valve from opening while the mower is mowing. E.g. this can be done manually through the GARDENA app or automatically through a schedule.

This function can only close the valve as quickly as possible in the event of a conflict. And a conflict may not be recognized either. So it can happen that water is let through. E.g. it cannot be prevented that the pop-up sprinklers extend and that the mower hits the pop-up sprinklers, but the likelihood that this will happen has been minimized. So it is up to your application to make sure that this conflict will never happen.

This adapter reports every value as a data point that is supplied via the GARDENA smart system API. If someone wants more values, please contact GARDENA and inform them that this value will also be included in the API. To do this, please go to Contact us & Leave feedback in the footer on the GARDENA Developer Portal.

This is a private project. I am not in any association with GARDENA or Husqvarna.
