These hubs are self-made IoT devices using [Raspberry Pi's](https://www.raspberrypi.com/products/raspberry-pi-4-model-b/) on [Raspbian](https://www.raspberrypi.com/software). They provide cameras and IR remotes to control televisions, which can be used with Chromecasts to project [AniNIX/Yggdrasil](../Yggdrasil/) media for users to view. Usually, they'll be wrapped in a maker case with a cellphone 5A charger on a wall mount.

# Relevant Files and Configuration
|
|
|
|
For the camera, we use the [motion](https://motion-project.github.io/motion_config.html) service to control the Raspberry Pi [camera module](https://www.raspberrypi.com/products/camera-module-v2/). This is reflected in the motion config.
|
|
|
|
For the IR control we use an [IR shield](https://www.amazon.com/s?k=Raspberry+pi+infrared+expansion+board+IR+transmitter&ref=nb_sb_noss) controlled by the [lircd](https://www.lirc.org/) service. As a note, in order for this to work, you have to set the pinout in the `/boot/config.txt` -- we try to default this in, but you may need to set `gpio_in_pin` and `gpio_out_pin` attributes for your particular board and shield.
|
|
|
|
We also set up an SNMPv3 daemon service on the hubs, to work with their IR control. This snmpd requires the Geth OVA to add snmpget using `apk update && apk add net-snmp-tools` from the `Terminal & SSH` add-on. Covers can then be added from the [command-line integration](https://www.home-assistant.io/integrations/command_line/). They'll look something like this:
