I'm just one of the beta users of home assistant who likes to help the developers.
Amazon Devices is a new integration part of the 2025.6 delivery and part of the feature is the automatic discovery of Alexa devices. These devices, when connected to local wifi, don't have the consistent hostname and we can only really discover them with MAC address discovery
We are looking to get some information from you, a first 6 hex digits of the MAC address of your Alexa device. This will be then put on the list for discovery.
You can see the MAC address with:
- Alexa app on your phone, devices -> your device -> device information
- In your wifi router if you know which device is Alexa
We have these root MAC addresses to discover Alexa for now. They are all part of Amazon reserved MAC list:

Amazon has many more reserved MAC roots, but at this point we are not sure if all of them can be used for Alexa or only part of them is. Objective is to reduce number of MAC addresses to the minimum needed. The list will likely evolve over the time
Thanks
