When I go to add actuator and choose Generic and the PWM output then when i head to select the connectivity option then a red ban icon appears on the place where i had to make a selection.
Why so ?
Please help me.

to add the PCA9685 for raspberry pi agent you will need to add this plugin GitHub - myDevicesIoT/cayenne-plugin-pca9685: A PCA9685 plugin for Cayenne

Have you connected your pca to your raspberry pi?


on your pi terminal, restart the service again and share the log.

cd /etc/myDevices/plugins
tail -f /var/log/myDevices/cayenne.log

Looking to drive a servo motor (0 to 180 degrees) using a slider control. Can anyone share a tutorial on how to do this so that I can do it easy?

there are two ways to do this:

  1. Add a pca9685 plugin to your cayenne pi agent and then modify the plugin code to work with servo motor.
  2. Use adafruit servo example code Adafruit_Python_PCA9685/simpletest.py at master · adafruit/Adafruit_Python_PCA9685 · GitHub and add the cayenne python example code Cayenne-MQTT-Python/examples at master · myDevicesIoT/Cayenne-MQTT-Python · GitHub. this is much easier as just combine the two examples.
