Works as it have to for a beginning.
michael 13.01.2025 Confirmed purchase
This is a home assistant-compatible device that allows you to communicate with your home assistant’s assist feature using voice commands. It works straight out of the box with minimal configuration required, especially if you’re familiar with the home assistant ecosystem.
Adrian 08.01.2025 Confirmed purchase Translated review
High expectations and unfortunately disappointment with the HA voice assistant. On the plus side, the workmanship and appearance. Unfortunately, the recognition of the keyword "OK Nabu" and messages are poor. Two microphones can no longer cope with a distance of 3 m. Maybe it's the fault of this particular specimen...
Jerzy 08.01.2025 Confirmed purchase Translated review
Official hardware from Home Assistant. At this stage it is ok. It works locally plus connects to online LLMs.
Maciek 08.01.2025 Confirmed purchase Translated review
I have no objections to the seller, only to the product itself. The product itself is currently underdeveloped - > understanding of commands (!), listening sensitivity or sound quality much below the capabilities of the basic nest mini (there is nothing to compare to larger ones). The speed of processing a query using Nabu Casa Cloud is comparable to Google services (as long as HA understands the query, which Google has no problem with, of course). At the beginning I did not expect miracles, but still something more for this price... We can only hope that the software and backend will improve over time.
Andrzej 06.01.2025 Confirmed purchase Translated review
The quality of the speaker is so-so. After connecting an external speaker, it is ok. Wakeword doesn't always work, but it's a Preview, so I have that in mind. The command recognition itself works ok. So far, the device does not hang. The overall quality is very good.
Wojciech 06.01.2025 Confirmed purchase Translated review
VPE is Nabu Casa's good entry into the home appliance market. Although the device has limited functions at the moment, its potential should be unlimited. I love the timer function (everything I used with my Google Home devices), although in Polish with the Nabu Casa cloud you call the timer by saying "set the stopwatch for 5 minutes". But apart from that, the device fulfills its functions unprofessionally.
Marcin 06.01.2025 Confirmed purchase Translated review
A great device. Your SmartHome will go to the next level.
Robert 06.01.2025 Confirmed purchase Translated review
Works great, no problems.
Dominik 06.01.2025 Confirmed purchase Translated review
The "Preview Edition" is in full swing. Onboarding is OK, but everything else is a failure for now. Poor capabilities, quite "homemade" workmanship. Clearly, this is a product for testing. It's a pity that Nabucasa didn't add a few months of HomeAssistant Cloud for free.
