core: Android TV integration - TV unavailable when turned of.

The problem

So I encoutered problem with my Android TV (TCL), where whenver I shutdown TV, it becomes unavailable in HA:

I did some debuging, and narrowed down problem to android TV itself.

When TV is on, NMAP results:

nmap 192.168.0.82
Starting Nmap 7.80 ( https://nmap.org ) at 2024-01-09 14:42 FLE Standard Time
Nmap scan report for 192.168.0.82
Host is up (0.0017s latency).
Not shown: 995 closed ports
PORT     STATE SERVICE
5555/tcp open  freeciv
8008/tcp open  http
8009/tcp open  ajp13
8443/tcp open  https-alt
9000/tcp open  cslistener
MAC Address: XX:XX:XX:XX:XX:XX

After TV gets shutdown, by any way remote/HA/auto sleep:

nmap 192.168.0.82
Starting Nmap 7.80 ( https://nmap.org ) at 2024-01-09 14:47 FLE Standard Time
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 1.02 seconds

I tried to change every tipe of settings in Android TV and nothing helped.

After some time I tried to wake up TV with WakeOnLan option and at first seems like TV had’nt woke up, however, nmap started responding with OK results, and TV become available (visible as turned off again) in HA again:

nmap 192.168.0.82
Starting Nmap 7.80 ( https://nmap.org ) at 2024-01-09 14:53 FLE Standard Time
Nmap scan report for 192.168.0.82

9000/tcp open  cslistener
MAC Address:

I know this happend not to all android TVs, however maybe you could add configuration option to enable, automaticaly resending WakeUpOnLan command, before the Heartbeat request, if tv is in Off/unavailable state?

Additional information

For anyone looking for fast fix, setting automation every 10s. to send magic wakeup packet, to TV’s MAC when TV is off/unavailable fixed the issue for me.
