labthings_fastapi.notifications
Handle notification of events, property, and action status changes
There are several kinds of “event” in the WoT vocabulary, not all of which
are called Event, which is why this module is called notifications.
In all cases, these are events that happen on an exposed Thing, and
may need to be relayed to one or more listeners (currently via a
WebSocket connection, though long polling may also be an option in the
future).
The aim at this stage (July 2023) is for a minimal working example that enables property changes to be fed via a websocket. Events proper should not be a big step thereafter.
Currently, this code is more or less all in websockets.py and
descriptors/property.py but it should get consolidated.
