Ensure your Device ID matches what is reported in Mason Controller. Here are some steps you can take to solve this problem
- Try visiting the device details page for your device inside Controller - ex:
https://platform.bymason.com/controller/devices/[DEVICE_ID]
- If you see an error message, the DEVICE_ID you are using does not map to a device in your Platform account
- If you see the device details page, verify that the device information on the details page matches what you expect to see
