Presence detection on an OpenWRT router

[piedro]

Just finished my presence detection based on querying an OpenWRT router through ssh, inspired by Chopper_Rob (arping based).

11:21:06- script started.
11:21:06- according to domoticz, E is online
11:21:06- E offline, tell domoticz
11:21:06- according to domoticz, F is offline
11:22:06- script started.
11:22:06- according to domoticz, E is offline
11:22:06- according to domoticz, F is offline

Code: Select all

Hi,

I've put up a script on GitHub which uses one openwrt master ap which can passively listen for events of any number of slave devices and resync in case events got lost e.g. during reboot. It emits connection, disconnection, present and away state for configured device mac's via flat file and fifos.

Link: https://forum.openwrt.org/t/script-how- ... -aps/52962

Put it to production and attached a fifo reader script on the master which toggles a virtual switch for every person's presence in domoticz via http json api - just works great.

It has a cooldown time built-in, so going into the garden will not immediately emit an away event. Moving to another ap will also not emit present-away-present but preserve the present status.

Have fun.
