Marcin 16.02.2025 Confirmed purchase Translated review

This is not a product for everyone. If you know what you are doing when you buy it, you will be satisfied. Easy integration, detects voice well, integrates with ai nicely. Only the quality of the built-in speaker is very average

Alexander 22.04.2025 Confirmed purchase Translated review

Unfortunately, only really usable with a paid subscription.

Krzysztof 21.04.2025 Confirmed purchase Translated review

It has potential for a preview edition. It sometimes crashes if you don't use it for a long time: wake word wakes it up, but it doesn't answer, you have to ask again. On orangepi zero 3 local speech to text is a slow, on the nabu cloud it works sensibly. It's worth playing around with GPT settings.

Przemysław 28.03.2025 Confirmed purchase Translated review

it's OK.

Michał 26.03.2025 Confirmed purchase Translated review

Works great

Alfonso 21.03.2025 Confirmed purchase

As always, good price, nice packing and timely delivery.💯

Roman 11.03.2025 Confirmed purchase Translated review

Works! But PE is PE, it lacks functions.

Szymon 18.02.2025 Confirmed purchase Translated review

Recommend. A great device that will connect IA with HomeAssistant and allow you to give voice commands. Of course, one device is enough for one room. So I have to buy another one 👍️

Stefan 17.02.2025 Confirmed purchase Translated review

So yes, it's a Preview Edition and not everything can work yet, but I would have expected a little more with the hardware. Wakeup not always possible, listen badly. Half of them don't understand. Etc. But what really annoys me, and you can't fix it with an update, is that you have to scream at a distance of 5 meters so that he wakes up, wakes up.

Hubert 14.02.2025 Confirmed purchase Translated review

Quickly and efficiently. Goods ok.

Tomasz 12.02.2025 Confirmed purchase Translated review

according to description

Hans 10.02.2025 Confirmed purchase Translated review

It's still a preview, but it has potential. 👍️🔥🚀

M. 10.02.2025 Confirmed purchase Translated review

In Time, right product, right packaging. I couldn't track the parcel in a proper way. But this is a parcel provider topic. Thx

Jacek 10.02.2025 Confirmed purchase Translated review

Great product. In combination with Home Assistant and GPT chat, I will finally talk to the assistant like in the movie "Why him" 🤣💪🔥

Robert 06.02.2025 Confirmed purchase Translated review

Everything as described Recommend 👍️

Paweł 06.02.2025 Confirmed purchase Translated review

The package was delivered even earlier than I expected :). The assistant is already up and running and everything works, and the best thing is that you can issue messages in Polish.

Dominik 06.02.2025 Confirmed purchase Translated review

Super product, superior to DIY spiders knitted and M5 Stack Atom Echo.

Rafał 06.02.2025 Confirmed purchase Translated review

I didn't get miracles and I didn't get them, but I hoped that this speaker would be a little better in quality, the sound is flat and a bit quiet. The lack of option to change the wake word individually is also poor. Besides, if you don't have time to build your own speaker, it's a good option. Something quick that you can play with today and connect gpt to the building control in a relatively easy way. It brings a lot of joy. But in some time, when I find time, I will build mine to make the sound clear and loud.

Jacek 06.02.2025 Confirmed purchase Translated review

After all, a decent speaker for Home Assistant, good microphone sensitivity, works stably even when the TV or radio is on.

Jaak 13.01.2025 Confirmed purchase

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.

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.

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.
