Beside the gateway (thing type "gateway"), the binding currently supports colored bulbs, dimmable warm white bulbs as well as white spectrum bulbs, control outlets and blinds.
The binding also supports read-only data from remote controls and motion sensors (e.g. the battery status).
The TRÅDFRI controller and sensor devices currently cannot be observed right away because they are communicating directly with the bulbs or lamps without routing their commands through the gateway.
This makes it nearly impossible to trigger events for pressed buttons.
We only can access some static data like the present status or battery level.
The thing type ids are defined according to the lighting devices defined for Zigbee Light Link ([see page 24, table 2](https://www.nxp.com/docs/en/user-guide/JN-UG-3091.pdf)).
For first pairing - the gateway requires a `host` parameter for the hostname or IP address and a `code`, which is the security code that is printed on the bottom of the gateway.
Optionally, a `port` can be configured, but any standard gateway uses the default port 5684.
The gateway requires at least firmware version 1.2.42 to connect to this binding.
The `code` is used during the initialization for retrieving unique identity and pre-shared key from the gateway and then it is discarded from the configuration.
The newly created authentication data is stored in advanced parameters `identity` and `preSharedKey`.
On each initialization if the code is present in the thing configuration - the `identity` and `preSharedKey` are recreated and the `code` is again discarded.
The devices require only a single (integer) parameter, which is their instance id. Unfortunately, this is not displayed anywhere in the IKEA app, but it seems that they are sequentially numbered starting with 65537 for the first device. If in doubt, use the auto-discovered things to find out the correct instance ids.
## Channels
The dimmable bulbs support the `brightness` channel.
The white spectrum bulbs additionally also support the `color_temperature` channel.
Full color bulbs support the `color_temperature` and `color` channels.
Brightness can be changed with the `color` channel.
The remote control and the motion sensor supports the `battery_level` and `battery_low` channels for reading the battery status.
-`fan_mode` and `fan_speed` channels, which allows for control of the fan and reading of the current speed.
-`disable_led` and `lock_button` channels, to respectively disable the LED's and lock the button on the physical device.
-`air_quality_pm25` and `air_quality_rating` channels, which reads the particulate matter 2.5μm and corresponding indication of air quality (similar to Tradfri app rating).
-`filter_check_next` and `filter_check_alarm` channels, which represents the remaining number of minutes until the next filter check and whether it is time to do the filter check now. Filter check must be completed through the TRÅDFRI app (or on the hardware buttons in case of replacement).
- a `filter_uptime` channel, which represents the current time since last filter change.
