The `lightwave` integration links Home Assistant with your Lightwave WiFi link for controlling Lightwave lights, switches and TRVs.
This integration uses the official API published by Lightwave on their website [https://api.lightwaverf.com/](https://api.lightwaverf.com/).
To add your Lightwave devices into your Home Assistant installation, add the following to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
lightwave:
host: IP_ADDRESS
lights:
R1D3:
name: Wall lights
R1D4:
name: Ceiling lights
switches:
R1D2:
name: Tree socket
R2D1:
name: Radio socket
R2D2:
name: Light socket
R2D3:
name: Phone socket
R2D4:
name: Torch socket
```
{% configuration %}

required: false
type: string

required: false
type: integer
default: 7878

type: string
{% endconfiguration %}
Where IP_ADDRESS is the IP address of your Lightwave hub.
Each `switch` or `light` requires an `id` and a `name`. The `id` takes the form `R#D#` where `R#` is the room number and `D#` is the device number.
`lights` and `switches` are optional but one of these must be present.
The first use of a light or switch will try to register with your Lightwave WiFi Link hub. If the hub has not been registered a message on your hub will be displayed asking you to pair the device. You have 12 seconds to push the button on your hub to accept this. Once done, you should be able to control your lights and switches via Home Assistant. This only needs to be done if the hub has not been registered.
# TRVs
Lightwave Thermostatic Radiator Values (TRV) are supported but require an additional proxy to capture the current TRV temperature.
See [LWProxy](https://github.com/ColinRobbins/Homeassistant-Lightwave-TRV)
```yaml
# Example TRV configuration.yaml for TRVs
lightwave:
host: IP_ADDRESS
lights:
R99D1:
name: Bedroom Light
trv:
proxy_ip: 127.0.0.1 # Proxy address, do not change unless running on a different server
proxy_port: 7878 # Do not change, unless a port clash
trvs:
R1Dh: # The ID of the TRV.
name: Bedroom TRV
serial: E84902 # Serial number of the TRV - found in the Lightwave App, or web site
```
