Hello,
I am currently working on a number of different voice assistant based projects. GassistPi has a number of features for both entertainment and home automation. There are branches to the GassistPi project like smart screen, volumio built-in with assistant, etc. Though the GassistPi is based on Google Assistant SDK, I am slowly working and annexing options to take it off Google’s grid. There is also another project or rather scripts called Assistant-Pi that will help people setup both Alexa and Google Assistant on a single Pi.
I am posting the Assistants’ details here just in case someone might find it interesting or might find it to match their use case or needs.
Regards
