C202/C202N - support for Home Assistant

Home Assistant - ZHA

  • It has come to our attention that a small batch of our zigbee rotary dimmers are not performing as expected with Home Assistant when using ZHA.
  • If you have recently purchased a rotary dimmer and are having problems with Home Assistant ZHA (the light toggle does not stay on, or the device appears in HA to toggle off/on occasionally), you may be able to update the firmware on the device. 
  • If your device is batch 7 or 8, and date code 20230401 please contact us to arrange a repair or replacement.
