Amazon Echo devices cannot be pinged, here is an alternative

I want my Home Automation to check if my Amazon Echo devices are present on the network or not. However, Amazon Echo devices cannot be pinged.

NMAP comes to your help (If you do not have NMAP installed, apt install nmap should solve the issue).

The following code will give you a 1, if an Amazon Echo device is present at the given IP address. It gives you a 0 if not.

nmap -T4 -F 192.168.178.120 | grep "host up)" | wc -l

Press Windows + R, type regedit in the run box that opens, and press enter.
If you get the following box,…

… press YES.

Go to the key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout

Right-click on the available space, click New and then select Binary Value.

Name it “Scancode Map” and enter the following binary value in the value data:

00 00 00 00 00 00 00 00
02 00 00 00 00 00 3A 00
00 00 00 00
