Are your piku apps running on your raspberry pi(s)? Deploy pikuboo to a piku server to track the last heartbeat time for all the piku apps on your local network.

Deploy to piku

git remote add piku $PIKU_SERVER:pikuboo
git push piku master

See Using piku.

Send a heartbeat

import os.path
def heartbeat(interval: float = 1.0, name: str = os.path.basename(os.path.dirname(os.path.realpath(__file__)))) -> None:
    import socket
    import time

    name_bytes = bytes(name, 'utf-8')
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    
    while True:
        sock.sendto(name_bytes, ('255.255.255.255', 5555))
        time.sleep(interval)

import threading
threading.Thread(target=heartbeat, daemon=True).start()
