Today Google has released some new IoT stuff, including Android Things and Weave. While the first one focuses mainly on hardware running a specific version of Android, which is not really of any use for Pimatic I think, Weave is definitely useful for Pimatic, as it allows for integration with Google Assistant, but the ecosystem is also expected to grow a lot.

At the moment I do not have a lot of time, but I’ll start looking into how this can be integrated into pimatic (probably with a plugin).
