LoFi as a Service

There is a public announcement speaker mounted to the cable tray in coucharea. It is connected to a Raspberry Pi, laas.asozial.it-syndikat.org, running https://git.it-syndikat.org/oha/laas. Can be controlled via a REST API, most easily through the entities already set up in Home Assistant.
