* Add mysensors notify platform
* Make add_devices optional in platform callback function.
* Use new argument structure for all existing mysensors platforms.
* Add notify platform.
* Update mysensors gateway.
* Refactor notify setup
* Enable discovery of notify platforms.
* Update and add tests for notify component and some platforms.
* Continue setup of notify platforms if a platform fails setup.
* Remove notify tests that check platform config. These tests are not
needed when config validation is used.
* Add config validation to APNS notify platform.
* Use discovery to set up mysensors notify platform.
* Add discovery_info to get_service and update tests
* Add discovery_info as keyword argument to the get_service function
signature and update all notify platforms.
* Update existing notify tests to check config validation using test
helper.
* Add removed tests back in that checked config in apns, command_line
and file platforms, but use config validation test helper to verify
config.
* Add a test for notify file to increase coverage.
* Fix some PEP issues.
* Fix comments and use more constants
* Move apns notify service under notify domain
GATEWAYS was a dict, so would overwrite item if key was the same. This
would happen when using multiple MQTT gateways, since the device id is
the same (`mqtt`).
* Fix by changing GATEWAYS from dict into list.
* Use hass data to store mysensors gateways instead of having GATEWAYS
be a global.
* Add MySensorsDeviceEntity class to hold the common attributes,
properties and methods for mysensors entities.
* Inherit from MySensorsDeviceEntity class in binary_sensor, light,
sensor and switch mysensors platforms.
* Remove not needed attribute and method for const in GatewayWrapper
class. The const attribute is already set in the wrapped object.
* Clean up state property for mysensors sensor entities.
* Inherit from MySensorsLightRGB in MySensorsLightRGBW class.
* Remove use of get_component in mysensors component and platforms.
* Clean up update method in MySensorsDeviceEntity class.
* Bump version of pymysensors to 0.6, which includes the tcp gateway.
* Update requirements_all.txt.
* Replace CONF_PORT with CONF_DEVICE and ATTR_PORT with ATTR_DEVICE.
* Add tcp_port in config.
* Try to guess if tcp or serial gateway is configured, by validating
device name as an ip address. If successful setup tcp gateway, if it
fails, setup serial gateway.
* Update device_state_attributes to show correct device, ethernet or
serial.
* Add mysensors binary sensor.
* Add discovery platforms to binary_sensor base component.
* Replace device_state_attributes with state_attributes in
binary_sensor base class.
* Fix docstrings.
* Add discovery of binary sensor to mysensors component.
* Add child.type as argument to mysensors device_class.
* Move binary sensor types from sensor to binary_sensor module.
* Fix binary_sensor attribute tests. Use state_attributes instead of
device_state_attributes.
