I’d assume you’d need a LAN version of this, which doesn’t exist, correct?
Thank you, you know how often it pings?
Haven’t used that app myself, sorry.
Looking at the code, the app sends an HTTP request address once per minute. If it misses more than three attempts in a row, it gets marked as offline/"not present". Both need an HTTP server on the other end. Despite the name of the former, neither looks like it does a true "ping" (i.e., over ICMP), just an HTTP request looking for a response of
OK). For a HomeBridge server, this would certainly work--just something to keep in mind in case you decide to use this with the hope of responding to arbitrary devices of other kinds on your network.
