Insteon dimmer online but not controlling light

  • Platform information: RPI 4
    • OS: OpenHabian 1.7.4b
    • openHAB version: 3.3
  • Issue of the topic:
    I installed the Insteon Binding and a PLM and Dimmer. All show as ONLINE. I can control the dimmer beep and LED on/off and even change the position of the LED with the dimmer slider, but the actual light that the dimmer controls does nothing. The light works fine physically using the dimmer switch. I just cannot seem to control it from OpenHab. The dimmer is obviously getting the messages sent from OpenHab, but why is the light not responding to either the dimmer level or the fast on/off?

Thanks for any advice you may have!
