node-red-node-blink1
A Node-RED node to control a Thingm Blink(1) LED.
Pre-requisites
As the blink1 is a USB HID device you may need some extra hardware libraries as documented here and here.
Specifically Ubuntu/Debian/Raspbian users may need to
sudo apt-get install libusb-1.0-0-dev
and also setup these udev rules in /etc/udev/rules.d/51-blink1.rules
SUBSYSTEM=="input", GROUP="input", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27b8", ATTRS{idProduct}=="01ed", MODE:="666", GROUP="plugdev"
Install
Run the following command in your Node-RED user directory - typically ~/.node-red
npm i node-red-node-blink1
Usage
Out
Sends the msg.payload to a Thingm Blink(1) LED device. The payload can be any of the following:
- a three part csv string of r,g,b - e.g. red is 255,0,0
- a hex colour #rrggbb - e.g. green is #00FF00
- a @cheerlights colour name - e.g. blue
The colours it accepts are - red, amber, green, blue, cyan, magenta, yellow, orange, pink, purple, white, warmwhite (or oldlace), black, (and off)
In
Outputs the current color value of the Blink(1) LED device in the msg.payload with the r,g,b values as an array e.g. [255,0,0].
If the Blink(1) is off the device returns 0,0,0. Instead of [0,0,0] the node returns "off".
