Mac mini M1

[duckdany]

I have changed from iMac 27" Late 2013 to Mac mini M1 (2020).
From Homebridge terminal shutdown command works fine but on my iPhone not working.
And the ping is not working anymore. I got this error:

I am writing this comment from my Mac mini, so it's online.
I couldn't try out the wake up or shutdown because HomeKit shows my Mac mini offline.

Is it because of M1 chip and ARM?

In the terminal on your Mac, run the following commands and post the output here.

Command 1:

pmset -g powerstate IODisplayWrangler

Command 2:

pmset -g powerstate IODisplayWrangler | tail -1 | cut -c29

As you can see from your config, this command is used to check whether or not your Mac is alive. It uses the pmset tool to check if the display is active, which is a better indicator in some cases than ping replies. It is possible that your Mac responds with something else than the command expects. We'll hopefully be able to see that soon enough though.

Here are examples of the output to expect.

Command 1:

      Driver ID  Current State  Max State  Current State Description
IODisplayWrangler           4          4  USEABLE

Command 2:

4

Digging around for an answer myself. Dug through all of the pmset information while SSH'd into a sleeping M1 Mac, and couldn't find any clear and obvious indicators that the machine was in a different state when comparing that output to the same machine awake.

Going to try to find some other commands outside of pmset perhaps that can be used as a test...

I believe I have a working solution now; gave up on SSH'ing in and checking any state, instead decided to try checking for open ports, as I know for instance things like AirPlay targets do go away when sleeping.

I had expected to find port 7001 as the AirPlay Receiver port but it didn't show as open; not sure how Apple devices actually negotiate all that, but I did discover that nmap will just fail to scan in general when the device is asleep.

So I'm using the following ping command now:
nmap -p7000 10.0.0.116 | grep open

[dillius]

So it turns out this check only works during the initial few seconds after sleep... not sure why. After that few seconds 7000 is responding again.

Next attempt appears to be working, slight modification of your original script Alex:

ssh -i /homebridge/my-key -o StrictHostKeyChecking=no user@host 'if [[ $(pmset -g useractivity | grep Present ) ]]; then; echo 1; else; exit 1; fi;'
