I posted about this recently but didn't get anywhere. I have set-up and configured two devices with the AndroidTV integration that are working well. I was seeking to get some disused tablets and phones integrated with HA too... to see what I could make them do for me.
I have been unable to hook them up. I get the error seen in the thread title. In my troubleshooting I can see that another machine can access the ADB over the wire on a test tablet but HA is not able to. I also ensured the container could ping the tablet successfully, but was unsure how to test the containers native ability to ADB in the same way (they adb command is not present it seems)
I was really looking forward to using old cellphones with HA... and felt this was the right direction... but no workie.
I have looked at the integration's troubleshooting. My devices are old... and I have not tried an external server... as I would prefer to keep it working with the integration alone.
Any suggestions on what I am doing wrong here?
