lightwave

Python library to provide a reliable communication link with LightWaveRF lights, switches and TRVs.

Installation

Either clone this repository and run python setup.py install, or install from pip using pip install lightwave.

API

This library makes use of the public API provided by lightwave that can be found here: https://api.lightwaverf.com/lighting_power.html

Lights and Switches

The library supports the following functions:

turn_on_light(device_id, name)
turn_on_switch(device_id, name)
turn_on_with_brightness(device_id, name, brightness)
turn_off(device_id, name)

Where:

• device_id takes the form R#D# where R# is the room number and D# is the device number.
• name is the text that will be displayed on the hub.
• brightness is a value from 0 (off) to 255 (full on).

Usage

Initialise a link to the hub by passing in the IP address required. Then call a method on the object to modify the device. The first time a switch is turned on or off the device will attempt to pair to the hub. This should then show a message on your WiFi Link asking you to pair the device. You have 12 seconds to push the button on the WiFi Link to accept this.

import asyncio
import time
from lightwave.lightwave import LWLink

async def main():
    lwLink = LWLink('192.168.15.226')

    print("Off")
    ### R1D3 is room 1 device 3
    lwLink.turn_off('R1D3', "Wall Lights")
    lwLink.turn_off('R1D4', "Ceiling Lights")

    time.sleep(5)
    print("On")
    lwLink.turn_on_light('R1D3', "Wall Lights")
    lwLink.turn_on_light('R1D4', "Ceiling Lights")

    time.sleep(5)
    print("Off")
    lwLink.turn_off('R1D3', "Wall Lights")
    lwLink.turn_off('R1D4', "Ceiling Lights")

    time.sleep(5)
    print("On")
    lwLink.turn_on_with_brightness('R1D3', "Wall Lights", 25)
    lwLink.turn_on_with_brightness('R1D4', "Ceiling Lights", 50)
    lwLink.turn_on_switch('R1D1', "Sockets one")
    lwLink.turn_on_switch('R1D2', "Sockets two")

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()

TRV Support

The library also supports TRVs with the following function:

set_temperature (device_id, temp, name)

Where:

• device_id takes the form R#D# where R# is the room number and D# is the device identifier (normally Dh).
• temp is the target temperature (0.5 increments)
• name is the text that will be displayed on the hub.

  TRV Proxy

  The Proxy is now optional. A built in listener is now available via the async function LW_listen().

Alternativly, to read the TRV status (current temperature, target_temperature, battery status and current output) a Lightwave TRV Proxy can be used. To use the proxy:

set_trv_proxy (proxy_ip, proxy_port)
(temp, targ, batt, output) = read_trv_status(serial)

Where:

• proxy_ip is the IP address of the proxy
• proxy_port is the IP Port of the proxy
• serial is the serial number of the TRV of interest (NB: This is the serial number, and NOT device_id they are different).
