new mac address every time the pc is restarted

every time the pc is restarted or turned off and on the mac address of the app changes and create new entities in Home Assistant also, the satellite must be reconfigured. How to prevent that?

This sounds like a windows issue unrelated to this app.

If you connect through wifi the randomize MAC address feature will cause this, disable it:

in Windows 11, go to Settings > Network & internet > Wi-Fi and toggle off "Random hardware addresses".

I'm heading same issue. My computer is connected to local network with Ethernet cable, and it's MAC address is fixed.

Nonetheless, I keep seeing strange MAC-address changes on ESPHome device. I thought that it may be because of other network adapters (although they are disabled), but none of them have this MAC. Mysterious.

Sometimes I'm enabling TUN-mode on NekoBox though, but I'm not sure if it's something that may change MAC.

I found that this was not just a Windows random-MAC problem on our side. The app was using the runtime MAC from the current environment, which could change across restarts or when virtual/VPN/TUN adapters were involved.

I have now changed the implementation so the app stores a persistent device identity in the user data directory and reuses the same MAC for both ESPHome and mDNS across restarts.

This should prevent Home Assistant from creating a new device identity every time the PC restarts.

The fix has been pushed to and will be included in the next release.

Correction: the fix has been pushed to main and will be included in the next release.
