Wake on Lan config flow

Wake on LAN can be quite useful for some automations.

But knowing the mac address and typing it in can be a real barrier to entry. Most of the time we are getting into semi expert level for people to know how to find out the mac address of a device.

I had some thoughts on how this could be done as a config flow. This post is a placeholder in case someone wants to pick it up (could be me at a later date!).

ping the broadcast address for the subnet, and wait

ping -b -i5 -c3

look at the arp table

cat /proc/net/arp

Then maybe use host or hostname to find out some network friendly device names if possible.

Then present a dropdown list to the user, allowing them to type the MAC address directly and edit the display name if they wish.
