Hey everyone. As you may remember we suffered a home invasion with nothing recorded but 5 seconds on each cam of 4 and I’ve been building my HomeKit. I nhad just gotten a M3 hun but had gotten chances to try. With the thermostat do we need just regular hvac or sensors? our bedroom is 15deg F differance. If anyone knows who could help replace my M3 or a used one. Thanks everyone so excited to see if we can get 4K on HomeKit so cams match the resolution

@KC.Croatian22 Hey there! Sorry to hear about the home invasion—hope things are starting to feel more secure as you build out your HomeKit setup. Let’s break down your questions:
For the thermostat and that 15°F bedroom temperature difference: The Hub M3 has a built-in 360° IR blaster that can link your AC to Matter and adjust it based on real-time room temperature from an Aqara Climate Sensor. This could help balance the temperature variance by letting the system respond to actual conditions in the room.
Regarding replacing or finding a used Hub M3, I don’t have specific info on that. You seem to be looking for assistance with Hub M3 replacement or a used unit. You can contact customer support for assistance.
As for 4K on HomeKit cameras, I don’t have details on that either. You seem to be interested in 4K resolution support for HomeKit cameras. You can contact customer support for assistance.

@fxr11 Hey @fxr11, sorry to hear you’re running into trouble with the Hub M3! That “device not supported” message can be frustrating, but let’s walk through some steps that often help resolve this.
Quick Troubleshooting Checklist:
-
Check App & Firmware – Make sure your Aqara Home app is updated to the latest version, and your Hub M3 firmware is also up to date.
-
Network Requirements – The Matter protocol (which M3 uses) has higher network demands. Ensure your WiFi router supports IPv6 and try toggling it off/on.
-
Same LAN Connection – If you have other Aqara Matter controllers (M3, M100, G5 Pro, etc.), make sure they and your phone are all on the same local network.
-
Hub Status – During setup, the gateway indicator light should be in a yellow fast-flashing state. If not, try resetting the hub by holding the reset button for about 10 seconds.
-
Restart Everything – Sometimes a fresh start helps. Restart your M3, router, and phone, then try adding the device again[“content_id”:4"].
-
App Reinstall – As a deeper fix, try completely deleting the Aqara Home app (clear data), restart your phone, then reinstall and try again[“content_id”:8"].
-
Hotspot Test – You can also try creating a phone hotspot with the same WiFi name/password, connect the hub to it, then switch back to your router to isolate if it’s a router issue[“content_id”:3"][“content_id”:8"].
If none of these work, it could be a compatibility or firmware issue specific to your Android setup. In that case, contact the Aqara Home App Customer Service Team (Profile > Help & Feedback > Customer Service) or scan the QR code below:

Hello, welcome to the forum. Is your M3 gateway designed for your region? Check regional restrictions.
If there are no problems with regional restrictions, I recommend making the first connection directly to the router using a cord. Later, the M3 (if you unplug the cord) will automatically see your router’s WiFi.

Hello,
everything have been done… App & firmware ok, app reinstall, firmware the app saiys it’s ok. Network wired to the M3, with IPv6 recognized on M3 and android mobile, Wifi in both 2,’ & 5 Ghz.
Yellow flash ok, M3 found, network ok, app says i’m going tu add a matter product and then always the same message “Access to this device is not currently supported.”

@fxr11 Hey fxr11! 
Thanks for sharing all the troubleshooting steps you’ve already taken—that’s some solid detective work on your end!
It sounds like you’re running into a Matter compatibility limitation with the Hub M3. Based on community discussions, Matter support for certain device types (like AC/thermostat controls) was still being developed in earlier firmware versions. The error “Access to this device is not currently supported” typically indicates the specific Matter device you’re trying to add isn’t yet compatible with the M3’s current implementation.
A few things worth double-checking:
- Ensure the Matter device itself is certified and designed to work with Aqara hubs
- Some Matter devices need to be added through their native app first before linking to the hub
- Matter devices may need to be added to each platform individually
Since you’ve already covered the basics (firmware, network, reset), this looks like a compatibility question that needs deeper investigation. You can contact customer support for assistance with this specific Matter device compatibility.

@fxr11 Hey @fxr11, I totally understand your frustration—going through all the troubleshooting steps and still not seeing the device in the accessories list is really tough, especially when you’re in Region France.
Since you’ve already contacted support and tried the standard tests, this might be a region-specific compatibility issue. Aqara devices rely on local servers and service support, and using devices outside their intended region can sometimes cause pairing or recognition problems. When there’s a region mismatch, you may need to submit a region unlock request in the Aqara App or contact Customer Support with your device SN for further assistance.
Also, double-check that your Aqara Home app region setting matches your actual location (Profile > Settings > Region), as incorrect region selection can cause devices to disappear or not appear. If you’re using multiple devices or phones, make sure you’re logged into the same Aqara account and region on all of them.
Since support has already given you the standard troubleshooting steps, I’d recommend reaching out again with your device SN and specifically mentioning the France region limitation. Contact the Aqara Home App Customer Service Team (Profile > Help & Feedback > Customer Service) or scan the QR code:

Hang in there—region issues can be tricky, but support should be able to help unlock things for you!

Hi, I know I’m going to get a lot of hate right now, but I recommend using an iPhone once to get started. If you have the opportunity, borrow someone’s iPhone for testing. Then everything will be fine on Android, I’ve had this happen to me from time to time.
Luckily, my wife has an iPhone.

Do you see the IP of the M3 gateway (IPv4) on the router?
Phone via WiFi and M3 gateway via wire - are they on the same IPv4 subnet?
