Issue: alexa is overlapping devices calls / Both Devices Triggering the Same Callback / Only one device showing out of multiple devices

[Debasish444x]

I encountered an issue where I had two devices and two callbacks, but both devices were triggering the same first callback instead of their respective ones.

Solution:
The problem was caused by the way the unique ID was generated in espalexa.h. To fix it, 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 corrected version:

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);

📌 File to Modify: espalexa.h (located in the ESPAlexa library folder)

Note:
I did not come up with this solution myself—I’m simply sharing it here so that others don’t waste an entire day troubleshooting like I did!
