@@ -124,3 +124,21 @@ The mqtt command to change the units is:
`mosquitto_pub -t home/OpenMQTTGateway/commands/MQTTtoSSD1306 -m '{"display-metric":false}'`
Please note that it may take several seconds/display updates for the units to change. This is due to the queueing of messages for display.
### Flip Display 180 degrees
This allows you to rotate the display 180 degrees. Can be set at compile time or during use, defaults to true.
The compiler directive is `-DDISPLAY_FLIP=false`
The mqtt command to change display orientation is:
`mosquitto_pub -t home/OpenMQTTGateway/commands/MQTTtoSSD1306 -m '{"display-flip":false}'`
Please note that it may take several seconds/display updates for the display to change. This is due to the queueing of messages for display.
### Display OpenMQTTGateway Logo when Idle
When this option is enabled the OLED display will show the OpenMQTTGateway Logo when it is idle. Defaults to false
The compiler directive is `-DDISPLAY_IDLE_LOGO=true`
