How many android devices are you talking about?

Are you using Homebridge ( I doubt it as your talking Android phones ) , I track devices via bluetooth using the homebridge-automation-bluetooth-presence plugin.
A snmpwalk might work:-

Not using Homebridge. Think I need to read up about SNMP which seems probably has the capability to read the ARP table which would still be the best solution as the network traffic monitoring devices is already done there. Perhaps later pfSense versions do SNMP better? Interacting with Bluetooth devices is also respectable, except the phones need to have it on (I presume) which is less likely and reliable than a phone connecting to the LAN.

Likely scenario is 3 androids and an intermittent iphone as well. The basic objective is
If {listed phone in house in last 5 minutes} then {turn on LAN Relay with timeout of say 15 minutes}
That allows Heater to run when someone home, and turn off relatively quickly when no one is home, and if no one is home for a day the heater won't run at all. New LAN relay commands overwrite existing commands, so update the timeout period. -
It seems like you should be able to do this fairly easily with IFTTT or a similar style app on each device.

Ouch. I think that involves registration with an external server to work, so if the Internet is down, our heater may not work. Not a good idea IMHO. I am looking to keep it local within the house.

I don't blame you. Something something something "the cloud"!
That's unfortunately how most of these things seem to work. I guess they do it for maximum compatibility, ease of setup etc.
It does seem like there should be an app that can do it locally though.

I think etc means the data is collected and is valuable to someone. I am not especially opposed to that (as much as some) but we need to keep our eyes open and realise the pros and cons of new offerings. If the data means I get a useful benefit with no downsides I am open to it. The need for an Internet connection has minimal benefit to me in terms of running a central heating system and the benefit of giving someone else the data of my heater's use (and other things) in trade for automation is not a convincing purchase for me.

Perhaps, the economic ducks need to line up for that. If a bit of code and low cost hardware can do the job for me I'd be happy with that, for awhile at least...! KISS -
@davo This dang kit is so damned kewl!
Even if I am running such an old image.....
snmpwalk [ip address of phone] -c public -v2c \iso.3.6.1.2.1.4.22.1.2.2.[ip address of phone]
when snmp is enabled....
gives
iso.3.6.1.2.1.4.22.1.2.2.[ip address of phone] = Hex-STRING: [Mac address of phone]
Thanks for the tips gurus. -
You probably just need to do an snmpget rather than a walk if you're just looking at an individual phone.

@nogbadthebad said in Presence of Androids - Home Automation - Linux PC accessing ARP table entries:

Yes that works too.
However the walk was helpful to examine the data to get the reference numbers. Not sure there is a material difference otherwise running snmpget or snmpwalk for a single result? -
I had the same question in the creation . And I want to ask-does linux allow you to do this?
-
Allow you to do what exactly?

snmpwalk & snmpget, if that’s the question the answer is yes, you’ll need to install the package.

This is cool, thank you for sharing

Thinking out loud ....
Would be cool to be able to "Fire an RMON" trap if that mac address is seen on the ??? - Switch or AP ...
Prob greatest chance on Switch .....Hmmm ...
Investigating what a HP 18xx switch can ...Damm HP 18xx ... Too simple , no RMON

At least two posts here are almost certainly spam. Be on the look out!

Yeah @bingo600 and @NogBadTheBad are very sus ;) hehehe

Ha!
