Aqara G350 Camera Hub and G400 Doorbell, Read From a Home Assistant House

I should say where I stand before anything else. I don't own a G350 or a G400, and nobody at this blog has had either one in hand. What follows is desk work: Aqara's own pages, three launch write-ups, two named hands-on reviews, Aqara's developer forum, the Matter Alpha coverage of Home Assistant's camera work, and Home Assistant's documentation. My house is a Home Assistant house with Reolink cameras and a Reolink PoE doorbell at the gate, so I read all of it as someone who already has a working answer and wants to know whether Aqara's is worth swapping in.

Bottom line: The G350 is the hub and the G400 is the doorbell, and the names are the first trap. For Home Assistant today, RTSP is the one path a named tester has confirmed on the G350. ONVIF is listed for the G400 and promised for the G350. Matter cameras in Home Assistant are real but experimental, so a "Matter-certified" camera isn't yet a Matter camera you can comfortably use there.

Which One Is the Hub, and Which One Is the Doorbell?

Aqara announced both on March 17, 2026. They ship together in the press material, they share a "G" and a 350/400 number, and a quick search for one drags in the other. So, plainly:

Specs come from Aqara's G350 and G400 product pages, with the doorbell's night mode taken from HomeKit News, and prices from The Gadgeteer and the Amazon listing quoted by iTechGuides. Aqara's press release leaves the price as an empty "$" placeholder, which is why I'm naming the outlets. Retail prices move, so check before you click buy.

One more naming snag: listings use "G400 (Wired)" and "G400 Select (Wired)" almost interchangeably. HomeKit News says its review unit was the Select bundle, which came with a three-month HomeGuardian cloud subscription. Match the model number to the box.

What Can Home Assistant Actually Do With Them?

Four routes are on offer, and they're not equally real. The graphic below is my summary; each cell traces to a source I name in the sections that follow.

RTSP: the route that works

Aqara's G350 page says it plainly: for Home Assistant, only streaming over RTSP is available. Derek Seaman, who reviewed the G350 in March on firmware 4.5.20, checked the streams with Scrypted and wrote that they worked as advertised, with the RTSP feed offered at up to 2160p. In Home Assistant that means the Generic Camera integration, where you supply a stream source URL and pick the RTSP transport. The same page warns that a higher frame rate can load both your network and the camera, which matters on a Wi-Fi camera pushing 4K.

What you get over RTSP is video. Pan, tilt and presets, AI detections and the privacy shutter stay inside Aqara's app. For plenty of houses that's fine. I want my cameras recording to local storage and showing up in dashboards, and RTSP does that.

ONVIF: listed for the doorbell, promised for the hub

This is where sources disagree, so here's the sequence. Aqara's G400 page says the doorbell works with Home Assistant over RTSP and ONVIF. HomeKit News's launch coverage lists ONVIF support for it too. A user on Aqara's forum says their Wi-Fi G400 runs with UniFi Protect without issues. I found no independent Home Assistant write-up, so the G400 line is a vendor claim with one anecdote behind it.

For the G350, Seaman reported that ONVIF PTZ control didn't work in March. In May, an Aqara staff member on the developer forum said Aqara generally offers ONVIF only on PoE cameras and would evaluate the G350. On October 13 the same account wrote that the evaluation was finished, that the G350 can support ONVIF, and that firmware would be done "in the next few weeks". That is a target and not a release.

Why does it matter? Home Assistant's ONVIF integration is the one that gives you PTZ actions and event sensors for motion and sound, and it needs a Profile S device with an H.264 stream. The G350 spec table lists H.264. The G400 pages don't say.

Matter: certified, and still waiting for Home Assistant

Aqara calls the G350 the first Matter-certified camera, and T-Break says it supports Matter 1.5. The certification is real in the sense that SmartThings can use it. The Gadgeteer's June roundup says SmartThings was the only major controller shipping Matter 1.5 camera support at that point, and that Matter camera video travels over Wi-Fi or Ethernet, not Thread.

Home Assistant is the interesting case, because the answer depends on which layer you mean. A timeline from the sources:

• March: Seaman added the G350 to Home Assistant over Matter and saw only a bridge, with no entities, sensors or diagnostics. He advised against onboarding it that way.
• April: a developer who inspected the Matter endpoint on firmware 4.5.21 reported it exposed a 1080p camera model, not the dual-lens one, with no PTZ, privacy mode, zones or siren, and a failing snapshot call. Live view and two-way audio worked in SmartThings.
• May 19: Matter Alpha reported that the Open Home Foundation's Matter.js Server 0.7.0 beta added experimental camera live view over WebRTC. On the G350 the audio and snapshot worked, and the stream "won't stream" yet.
• August 18: firmware 4.5.70 added PTZ over Matter, and the camera then reports Matter 1.5.1, according to Matter Alpha. The features worked through SmartThings and the Matter Server, but Home Assistant's regular frontend hadn't exposed the full camera experience, and Matter Alpha called Home Assistant's camera support experimental.
• October 20: Matter Server 1.5.0 (beta) adds two-way camera audio through a talkback option and names the G350 as an example, per Matter Alpha. You have to switch on the beta in the Matter Server settings, and most of the new features still need work in Home Assistant Core.

Home Assistant's own Matter page doesn't list cameras among its device-specific sections. So is the G350 a Matter camera in Home Assistant? The server can talk to it, an experimental dashboard can show it, and the everyday integration isn't finished. Calling it "supported" would be generous. Calling it "doesn't work" would be out of date.

Do the Hub Roles Matter in a House With a Coordinator?

This is the part the product name sells hardest, and it's the part I'd weigh least.

The G350 is also a Zigbee hub, a Matter controller and bridge, and carries a Thread radio. Aqara's press release describes it as bridging Aqara Zigbee devices into Matter ecosystems. If your Zigbee devices already sit behind a USB coordinator on the Home Assistant machine, which is how my own build is set up with a Home Assistant Connect ZBT-1, does a second Zigbee hub earn its place? A second Zigbee hub is a second network to look after. Seaman did observe that the G350 shows up in Home Assistant as a Matter bridge, and he reported no entities from it in March. I haven't seen anyone test Zigbee devices exposed through it, so I won't guess.

Thread deserves more care. Aqara's G350 page lists only a Zigbee/Thread 802.15.4 radio. Launch coverage from HomeKit News and The Gadgeteer calls it a Thread Border Router. Seaman saw it behave like one: during onboarding it joined his existing Apple Thread network. He also found that it supports only Thread 1.3 with no TREL on that firmware, and that he couldn't find a way to turn the border router role off. His network, 75-plus devices, stayed stable.

Home Assistant's Thread documentation explains why that behaviour deserves attention: each vendor normally forms its own Thread network, devices can't roam between those networks, and the preferred-network function isn't fully implemented. A camera that joins whichever network is around, or starts its own if none exists, is one more vote in a mesh you may be trying to keep single. My Thread setup guide covers how to decide that before you buy, and the Thread, Zigbee and Matter comparison covers when a Thread-heavy house even needs one.

How Much Resolution Do You Keep?

A 4K sensor doesn't promise a 4K picture at the other end. So where do the pixels go? Each stage has its own cap, and the sources don't all agree.

The G350 page says Apple Home limits it to 1080p and may lower it further on a poor network. Aqara's G400 page puts Apple Home at 1200p, while HomeKit News's reviewer wrote that the doorbell is limited to 1080p outside Aqara's ecosystem and that 2K is only available when you use it solely within Aqara's app. Both numbers are in the graphic because I can't reconcile them from here.

For a Home Assistant house the practical reading is simple. If you want the full picture, RTSP is your door. If you want recordings and AI summaries, those depend on a microSD card plus Aqara's HomeGuardian cloud tier, whose price I couldn't find.

Is the G400 a Sensible Doorbell for Home Assistant?

On paper, yes. It runs on PoE or doorbell wiring, there's no battery mode at all, it's rated IP65, and it records to a card. At $99.99 it's priced like a mid-range doorbell, and Aqara lists the two protocols a Home Assistant user wants.

The catches are practical. Per iTechGuides the G400 can't drive your existing chime, and HomeKit News says the included one connects over RF433. HomeKit News's reviewer hit intermittent "network connection failed" messages in Aqara's app, which a software fix improved but did not fully clear, and noted that the motion sensor is pixel-based, not PIR. That reviewer didn't use PoE or test RTSP, so nobody has yet put the Home Assistant side of this doorbell on the record.

My own gate has a Reolink PoE doorbell with its chime, and the PoE cable went in alongside the electrical work before the plaster, so power was never a question. I picked the Reolink for RTSP and an official Home Assistant integration. Would I swap? Not without a documented Home Assistant setup for the G400. If you're retrofitting and have PoE or a doorbell transformer at the door, it's a candidate worth watching.

What Is Still Unconfirmed?

Writing this up turned up as many gaps as facts. Which gaps would change my verdict? The first two below.

• ONVIF on the G350. Promised for "the next few weeks" as of October 13. No release found.
• ONVIF and RTSP on the G400 in Home Assistant. Listed by Aqara, with no independent walkthrough.
• The G400's video codec. Home Assistant's ONVIF integration needs H.264.
• RTSP detail on both cameras. Aqara's pages give one sentence.
• Night-vision range for either camera.
• Zigbee device limits. One summary I saw quoted sub-device counts, but Aqara's G350 page didn't state them, so I'm not repeating a number.
• HomeGuardian pricing. Not stated on any page I read.
• Whether the G400 does anything over Thread or Matter. Aqara's page is silent, and iTechGuides says it isn't Matter-certified.

Who Should Buy What?

My position, stated so you can disagree with it: buy the G350 for the camera and treat everything else on the box as a bonus you may never switch on.

If you want a pan-tilt indoor camera with a real telephoto lens, local card storage and a stream Home Assistant can show today, the G350 earns its $139.99 on those terms alone. If you were hoping the Zigbee hub, Matter bridge and Thread radio would simplify a Home Assistant house, they won't, and they might add a second network you didn't ask for. If you're buying it for Matter in Home Assistant, wait. The server work is moving, and the October beta shows it, but the everyday experience isn't there yet.

The G400 is a decent wired doorbell candidate for anyone who already has PoE or transformer wiring at the door and wants RTSP, with two warnings. Nobody has published a working Home Assistant configuration, and its full 2K picture is reportedly reserved for Aqara's own app. For a doorbell, I'd want that proof before spending $99.99, and my security camera roundup lists the picks I'd compare it against.

What Should You Check Before Ordering?

1. The model. G350 or G400, and "Select" or not. The names collide, the SKUs don't.
2. Your firmware. Matter behaviour changed between 4.5.20, 4.5.21 and 4.5.70. The newest release matters more than any review, this one included.
3. Your Thread network. Decide whether the G350's radio is welcome before it joins one. The Apple Home Collection post shows the same border-router question from Apple's side.
4. Your doorbell power. PoE, or a transformer on the right rating. Aqara's page lists AC24V, AC18V, AC16V and AC12V as recommended and AC8V or AC10V as not recommended.
5. Your storage plan. The card is sold separately, and the cloud tier is a subscription. If local storage is the point, as it is for me, check both before you count the price.
6. Your expectations for Matter. Read the Aqara compatibility guide for what works with what, and if a camera is your first Matter purchase, my Shelly Camera post judges a cheaper RTSP camera by the same rules.

The question I'd ask of any camera in a house like this is where the video ends up and who can switch it off. I explain how I weigh claims like these on the how we test page. If Aqara ships ONVIF for the G350 in the next few weeks, or someone posts a working G400 setup, I'll rewrite this around it.
