Ulanzi Smart Pixel Clock

I played with the Ulanzi Smart Pixel Clock and flashed the custom firmware awtrix3

Setup the Smart Pixel Clock e.g. WIFI password, IP of the MQTT broker (the system you will be sending commands from) and update the time zone (e.g. Europe/Berlin = CET-1CEST,M3.5.0,M10.5.0/3()

For details on the MQTT API check this documentation.

Here are some examples with Mosquitto and curl:

Control device using Mosquitto

Start mosquitto

mosquitto -v

Monitor MQTT topics:

mosquitto_sub -h localhost -t "awtrix/#"

Send a message:

mosquitto_pub -h localhost -t "awtrix/notify" -m '{"text":"Hello, Awtrix!","rainbow":true,"duration":10}'

Show a red arrow on the top right corner

mosquitto_pub -h localhost -t "awtrix/indicator1" -m '{"color":[255,0,0],"blink":1000}'

Remove the arrow again:

mosquitto_pub -h localhost -t "awtrix/indicator1" -m '{"color":[0,0,0]}'

Control device using Curl

Same commands as above using curl:

curl -X POST --data '{"color":[0,0,0]}' -H 'Content-Type: application/json' 'http://1.2.3.4/api/indicator1'

curl -X POST --data '{"color":[255,0,0],"blink":1000}' -H 'Content-Type: application/json' 'http://1.2.3.4/api/indicator1'

curl -X POST --data '{"text":"LOL 0xfab1","rainbow":true}' -H 'Content-Type: application/json' 'http://1.2.3.4/api/notify'
