It's still probably library. This has worked for a lot of people, including me. If it doesn't for you, I had issues with generations earlier than the 4. I bought one gen 4, and suddenly everything worked. This was a few years ago, before the library became an issue.

"Open espalexa.h in an editor and search for encodeLightId

in the encodeLightId method, replace the line that assigns the ID,

Replace this line : sprintf_P(out, PSTR("%02X:%02X:%02X:%02X:%02X:%02X:00:11-%02X"), mac[0],mac[1],mac[2 ],mac[3],mac[4],mac[5], idx);

With this line: sprintf_P(out, PSTR("%02X:%02X:%02X:%02X:%02X:%02X-%02X-00:11"), mac[0],mac[1],mac[2 ],mac[3],mac[4],mac[5], idx);

save the espalexa.h file and upload your sketch again, the on Alexa app discover the devices again you will see all the devices.
give it a little time and you will see "ON" buttons with the devices"
