I have no interest myself, but if I wanted a home assistent I would take an Amazon Echo (either from a dumpster, or 2nd-hand), and put lineageOS on it to liberate it. The more Amazon hardware that gets converted to a liberated platform, the better. People have done this successfully with the Echoes that have a screen, but the headless Echoes need the same motivation and effort so we can liberate those too. Otherwise they are going to waste.
