Hello, I have broker mosquit with user and password:
How I can set ospiLCD-mqtt.py configuration file?
I tried like this:
mqttAddress = “192.168.1.52”
mqttPort = “1883”
mqttUser = “mqtt_user”
mqttPassword = “mypassword”
but not working:
root@opensprinkler:/home/pi# ./ospiLCD-mqtt.py
Traceback (most recent call last):
File “./ospiLCD-mqtt.py”, line 231, in <module>
dotsize=8, charmap=’A02′, auto_linebreaks=True, backlight_enabled=True)
