Home Assistant Green makes smart home setup feel simple without giving up power or flexibility. In my experience, it was a world of difference when using all my smart home devices locally, because everything responded faster, felt more reliable, and stayed under one control system instead of scattered across separate apps and cloud services. What stands out most is how well it brings devices together in one place. Lights, sensors, thermostats, and an infinite of other gear that can be managed from a single dashboard, and local control means fewer delays and less dependence on outside services. It also feels like the only long-term solution, especially if you want privacy, quick automations, and a setup that can grow with your home. Overall, Home Assistant Green is the kind of upgrade that quietly changes how you use your home every day. It’s affordable, easy to start with, and powerful enough to make local automation feel like the default way smart homes should work.

Home Assistant is amazing! It breaks down all the walled gardens between Smart Home vendors like Lutron, Google Home, Amazon Alexa, etc. Ex. I can now use the Lutron motion sensor to control all other smart home devices that could not talk to Lutron directly. It also fixes stupid bugs like the Arlo Video Doorbell no longer announcing motion on Amazon Echo devices via Alexa; I can now use Home Assistant to announce motion on the Arlo Doorbell on Echos and Sonos and other speakers around the house. It also enables truly hands-free automations like setting the correct Philips Hue lighting scenes whenever I start or stop video playback on a Zidoo video player. These examples are just scratching the surface. Home Assistant, using local control, responds much faster and more reliability than cloud-based automation platforms like Alexa and Google Home. It's also compatible with so many more devices than the cloud-based platforms. Don't let the Home Assistant's geeky reputation scare you away. The Home Assistant Green device is completely plug-and-play. Make sure you install the HACS (Home Assistant Community Store) to get the most out of HA. Amazon wants me to say something about size: the Home Assistant Green is tiny and unobtrusive, you can tug it away anywhere.

I ended up buying this device about 2 months ago when the Alexa devices could no longer access the Sengled cloud servers. This change rendered most of my smart bulbs useless via Alexa voice control, so that’s how I landed on Home Assistant Green. I admittedly did not do enough research to truly understand what I was buying and I’ve spent the last 2 months experimenting and this ultimately was a great purchase for me. In addition to the cost of the Home Assistant Green (Which isn’t peanuts necessarily) I had to buy 4 additional antennas so HA could communicate with the various devices I have. Another cost was a powered USB hub so I could connect all 4 USB antennas at once; due to HA only having 2 USB ports. These are all relatively cheap antennas (around $20-25/a piece) but costs are slowly adding up. To be fair though, HA did discover a lot of my devices just out of the box and hardwired to my router, so if you just need the basics, then you might not need to purchase anything additional depending on your device setup. BUT, if you do want more control and flexibility with your current mixed brand smart devices, then HA with a couple of small add-ons is the way to go. The reason I would say this isn’t exactly for beginners is because it’s not necessarily a plug n’ play setup like it is setting up devices in Amazon Alexa. Depending on your devices and how easily they integrate with Home Assistant Green would determine the level of experience needed to fully leverage the automation capabilities of the Home Assistant. I’ve been able to move all of my smart home devices under one roof now through Home Assistant and utilize local control all while maintaining voice control with Alexa via the Home Assistant Cloud subscription. All in all this has been a great little investment and with some effort to learn on my part, I’ve really been able to dial in control over my home smart devices and setup some automations that are only possible through Home Assistant Green (and possibly other “like devices”).

Just really started working with this tech. Easy setup and runs without issue. Hope there are not problems. But you can schedule backups.

The product came as advertised. Well packaged and appealing. Easy to install and this is really plug and play. A nice touch is the power plug section which has adapters for most countries so no additional adapters required. Connectivity to current systems and discovery of devices within the home is like magic, when you look it is there. For beginners it is well worth noting that you may have to connect your ESPHome device directly to the Home Assistant Green hub, to flash the ESP for the first time. It does not seem to compile for the USB device on your computer. All in all a really great product

They're not kidding when they say this will be your new hobby. Open a browser window on your computer and another with AI to walk you through because you will NEVER figure it out by trial and error. That said, it works wonderfully and has tons of software/hardware integrations. I was able to take my many non-Apple devices and get them working great with Apple Home thanks to the Homekit Bridge on this device. It's a process but once it's done you can Siri-operate every device you have.

I like to consider home assistant the god of smart home hubs, and so far it is. There’s tons of things you can do, and any compatible devices (which includes a lot) can work together seamlessly. As far as connectivity goes, it connects to your home network with Ethernet, requiring no wireless setup, and from there can run everything locally. This results in almost instant response times from automations, not to mention the amount of flexibility you get when setting those automations up to begin with. Yes, this may be a pricy way of setting up a smart home, but so far it’s been worth it.

The HA Green works well and does a nice job of keeping itself updated. Unless you want to spend the maintaining servers, this little divide does what it needs to with minimal effort.
