Thanks @rontally and @WB70. I am still struggling with this issue.
I followed @rontalley’s steps and realised the following:
- The offline marker is removed from the virtual switch on the Alexa console
- The voice command issued to Alexa immediately after following the steps is successful
- Any subsequent voice commands fail.
I have also tried @WB70’s steps.
- All the devices are relisted on the Alexa console marked as ‘offline’
- Voice commands fail
Something must have changed in the past week or so as I have never experienced this issue.
