# HAPT | ||
|
||
Home Assistant Presence Tracker (HAPT) is an event-driven device presence tracker for [Home Assistant](https://www.home-assistant.io/) on an OpenWRT router or access point. | ||
Home Assistant Presence Tracker (HAPT) is an event-driven device presence tracker for [Home Assistant][homeassistant] on | ||
an OpenWRT router or access point. | ||
|
||
## Description | ||
|
||
Coming soon... | ||
HAPT listens on association and disassociation events to wireless networks, using the hostapd control interface. It | ||
keeps track of which device is connected to which networks. When a device connects to its first network, or disconnects | ||
from its last network, a service call to Home Assistant is performed to mark the device as home or away. By tracking | ||
active device connections, HAPT ensures that a device switching between different networks (e.g. the 2.4 GHz and 5 GHz | ||
bands) is not marked as away. | ||
|
||
## Usage | ||
|
||
### Installation | ||
Download a package from the [releases][releases] page, and install it either by uploading it in LuCi (System > Software) | ||
or running `opkg install <file>` from a shell. | ||
|
||
### Configuration | ||
Once the package is installed, you must update the configuration in `/etc/config/hapt`. At minimum the `host` option | ||
should be set to the address of your Home Assistant installation, and the `token` option to a Home Assistant | ||
[long-lived access token][token] (these can be generated in the Home Assistant web interface). | ||
|
||
The `consider_home_timeout` and `consider_home_disconnect` settings can be used to configure for how long (in seconds) | ||
after the first association and last disassociation event the device should be considered home. Since Home Assistant | ||
does not support marking a device as away (on disconnects), this is implemented by marking the device as home for a | ||
negligible amount of time, after which Home Assistant will mark the device as away. The default values should be fine | ||
here. | ||
|
||
With the `wifi_interfaces` option, it is possible to specify the wireless interfaces that must be monitored. This can be | ||
used (for example) to ignore devices on a guest network. | ||
|
||
### Running | ||
After modifying the configuration, you must restart the service by `service hapt restart`. This can also be done from | ||
the LuCi interface (System > Startup). HAPT prints log messages to the system log, so that you can verify it is working | ||
as expected. | ||
|
||
It is possible to synchronize just the currently connected devices with Home Assistant by running `hapt` from the | ||
command line. This can be especially useful to debug the connection with Home Assistant, as this will also print any | ||
errors that occur. | ||
|
||
## Development | ||
You can build a custom package by running the `makepkg.sh` script, which will run the package build in a Docker | ||
container and place the compiled package in the `build/bin` directory. | ||
