  • Our tech is simply not there to put proper speakers and microphones AND a well sized battery in something so small.

    Especially speakers. Volume is determined by the amount of air the diaphragm can move - and there’s an exponential relationship between the size of the diaphragm and the volume of air it moves. Large diaphragm: even small movements (low amplification) can be loud because of how much air you move. Small diaphragm: even at high amplification, the volume will be low.

    Smartphone speakers work this around by having an actually large speaker with appropriate sized cavity tucked away. Like, look at an iPhone teardown and see just how big the speakers are for the mediocre volume they can output. A combadge is what, 1/5 the size of the largest iPhone, in volume? And you still need to put electronics AND a battery in there.

    It could work as a microphone, but not as a speaker.








  • Well yeah, the availability of these more advanced hardware bits is pretty new - for example, all the older GH Minis and Echo devices were running a quite pared down Linux distro with software processing for e.g. wake words.

    Transplanting all that to MCUs takes time, but now we have a solid base, a handful of devices/boards that utilise the various XMOS chips, and soon we will be seeing more and more consumer level devices - but again that takes time when there’s no big megacorp behind the project pushing it to completion with bottomless finances and hundreds of engineers.

    But you’re not exactly correct on there being no other options. There’s the Satellite1 smart speaker which might be a DIY kit but it does exist. Then there’s the Seeed Studio Respeaker Lite w/ ESP32-S3 to which you can slap a speaker (either directly or a powered speaker through the audio jack). In fact the Respeaker lineup has a handful more options for smart speakers all utilising the various XMOS chips.

    Just keep in mind that these speakers are DIY mainly for two reasons:

    • the technology is pretty new
    • there’s no big corpo push behind it to deliver profitable (in some way) consumer products

    There WILL be consumer products (hopefully soon) on the market, but again, this is being done by volunteers and small startups with just a handful of people, it takes more time to get them on the market than it does for companies the size of Amazon or Google.




  • The HA Voice Preview is a pretty solid device, but you’re right, there isn’t really any ready made Echo/Google Home Mini replacement device - primarily because all those devices are generally sold at a loss, or at cost at best, and subsidised by your data being sold.

    You won’t be able to make a Google Home Mini contender for below $50, and at that price most people will opt for the former. Good quality speakers, microphones, local processing (like the XMOS chip in the Voice Preview) all cost money, and there’s no subsidy to be made. Some older Echo devices are rootable, but the hardware tends to be somewhat exotic (meaning no open source support for specialised components), and there’s little ongoing third party support (focus has been on the display-equipped models, and to run Android on them).

    All in all, “cheap” and “fully local open source voice assistant” don’t really coexist.



  • I’m sorry, what?

    Googling “home assistant Spotify” results in the very link you’ve provided.

    And you can hardly expect a project like Home Assistant, with THOUSANDS of first party integrations, to cater to your specific needs, or to provide preferential treatment to companies like Spotify, who provide absolutely no support to the project.

    It also doesn’t require a “techie setup”, but following a quite straightforward guide, that culminates in clicking about maybe a dozen buttons (most of them being “I accept” to various terms and policies), then copying a handful of readily provided strings into the right fields. It’s simple enough that even my tech illiterate father can do it.

    Home Assistant at the end of the day is NOT an Alexa (or other voice assistant) replacement, but a smarthome control hub OS. That it provides a voice assistant interface is quite secondary to its main mission.
