How can you see the MAC address of a ESP8266 or 32 when using ESPHome?

ESPHome

I have added several ESP8266 and ESP32s to HA, I want to reserve the IP address on my router, but need the MAC Address to do that. When you upload the firmware to the module it shows the BSSID MAC address (router) but not the MAC of the module.

Is there a way to see the modules MAC address?
Thanks.

I use Advanced IP Scanner on PC which will show you all connected devices including MAC.

Once you know the IP address, run

arp 192.168.20.140

Thanks, Advances IP Scanner worked very well, it showed everything that the router knew about.

Thanks - arp was so much simpler than other sites …
