WhatA dedicated microphone array module with beamforming and optimized on-device wake word detection, designed as a drop-in satellite for Home Assistant and other open voice platforms.
SignalMultiple commenters independently identify wake word detection as the single biggest bottleneck — their local assistants are smarter than Alexa or Google but fail because the device doesn't reliably hear the wake word, and one user says they'd immediately buy several units if this were solved.
Why NowAmazon's Echo hardware excellence is no longer paired with a good software experience due to ad injection, creating a window where superior open hardware paired with open software can win; MEMS microphone arrays and edge ML chips have become cheap enough for a sub-$50 BOM.
MarketHome Assistant's 1M+ active installations as initial beachhead, expanding to broader smart home market; buyers would pay $40-80 per room; no current open hardware competitor does this well.
MoatPurpose-built DSP firmware and acoustic models tuned to real-home environments create a data flywheel — each deployment improves wake word accuracy, which is extremely hard to replicate without deployed hardware collecting noise profiles.
