What’s the Manufacturer code listed under the Advanced Web App for this device? Most Jasco devices sold under the GE or Embrighten name use 0063-XXXX-XXXX. The Honeywell versions are usually 0039-XXXX-XXXX.
Both Zwave Switch CS and Zwave Fan CS support both the 0063-4944-3131 and 0039-4944-3131 devices already. Zwave Fan CS adds the ability to set the fan speed differently with voice assistants, if you need that feature.
