# Easee Binding
The Easee binding can be used to retrieve data from the Easee Cloud API and also to control your wallbox via the Cloud API. This allows you to dynamically adjust the charge current for your car depending on production of your solar plant.
# Supported Things
This binding provides three thing types:
| Thing/Bridge | Thing Type | Description |
|---|---|---|
| bridge | site | cloud connection to a site within an Easee account |
| thing | charger | the physical charger which is connected to a circuit within the given site |
| thing | mastercharger | like the "normal" charger but with additional capability to control the circuit |
Basically any Easee wallbox that supports the Cloud API should automatically be supported by this binding.
# Discovery
Auto-discovery is supported and will discover all circuits and chargers assigned to a given site.
# Bridge Configuration
The following configuration parameters are available for the binding/bridge:
| Configuration Parameter | Required | Description |
|---|---|---|
| username | yes | The username to login at Easee Cloud service. This should be an e-mail address or phone number. |
| passord | yes | Your password to login at Easee Cloud service. |
| siteId | yes | The ID of the site containing the wallbox(es) and circuit(s) that should be integrated into openHAB. The ID of your site can be found via the sites overview (https://easee.cloud/sites (opens new window)). You just need to click one of the sites listed there, the id will be part of the URL which is then opened. It will be a number with typically 6 digits. |
| dataPollingInterval | no | Interval (seconds) in which live data values are retrieved from the Easee Cloud API. (default = 120) |
# Thing configuration
It is recommended to use auto discovery which does not require further configuration. If manual configuration is preferred you need to specify configuration as below.
# Charger
| Configuration Parameter | Required | Description |
|---|---|---|
| id | yes | The id of the charger that will be represented by this thing. |
# Mastercharger
| Configuration Parameter | Required | Description |
|---|---|---|
| id | yes | The id of the charger that will be represented by this thing. |
| circuitId | yes | The id of the circuit that is controlled by this charger. |
# Channels
The binding only supports a subset of the available endpoints provided by the Easee Cloud API. The tables below show all available channels and which of them are writable. The settings that start with "dynamic" can be changed frequently, the others are written to flash and thus should not be changed too often as this could result in damage of your flash.
