Hi may I know how you got Alexa to work with this setup? I’m assuming by Alexa, you mean Alexa Smart Home Skill?
I’m running Hassio on Synology Docker too, but I can’t seem to get that working by following those instructions above.
I suspect it’s due to port forwarding issues, even though I’ve set up DuckDNS as instructed.
Would appreciate any advice regarding this. Thank you!
