# Automower Binding

This is the binding for [Husqvarna Automower a robotic lawn mowers](https://www.husqvarna.com/uk/products/robotic-lawn-mowers/).
This binding allows you to integrate, view and control Automower lawn mowers in the openHAB environment.

## Supported Things

`bridge:` The bridge needs to be configured with credentials and an application key that allows communicating with the Automower Connect API

`automower:` A single Husqvarna Automower robot

All Husqvarna Automower models with "Automower Connect" should be supported. It was tested only with a Husqvarna Automower 430X and 450X.

## Discovery

Once the bridge is created and configured, OpenHab will automatically discover all Automowers registered on your account.

## Thing Configuration

`bridge:`

- appKey (mandatory): The Application Key is required to communicate with the Automower Connect API. It can be obtained by registering an Application on [the Husqvarna Website](https://developer.husqvarnagroup.cloud/). This application also needs to be connected to the ["Authentication API" and the "Automower Connect API"](https://developer.husqvarnagroup.cloud/docs/getting-started)
- appSecret (mandatory): The Application Secret is required to communicate with the Automower Connect API. It can be obtained by registering an Application on [the Husqvarna Website](https://developer.husqvarnagroup.cloud/).
- pollingInterval (optional): How often the bridge state should be queried in seconds. Default is 1h (3600s)

Keep in mind that the status of the bridge should not be queried too often.
According to the Husqvarna documentation not more than 10000 requests per month and application key are allowed.
With the default value of 1h this would mean ~720 requests per month for the bridge state

`automower:`

- mowerId (mandatory): The Id of an automower as used by the Automower Connect Api to identify a mower. This is automatically filled when the thing is discovered
- pollingInterval (optional): How often the current automower state should be polled in seconds. Default is 10min (600s)

Keep in mind that the status of the Automowers should not be queried too often.
According to the Husqvarna documentation, no more than 10000 requests per month and application key are allowed.
With the default value of 10min this would mean ~4300 requests per month per single Automower

| park_until_further_notice   | Switch   | W | Park the Automower until further notice.                |

### Position Channels

These channels hold the last 50 GPS positions recorded by the Automower, thus describing the path it followed.
Position 01 is the latest recorded position, the other positions are pushed back, thus removing the previous position 50 from the list because it is replaced by the previous position 49.
Channel `last-position` is always identical with channel `position01` and thus provides more convenient access if only the latest GPS information is required by the user.
