Looking for network guru guidance on GT-AXE16000 + X-Sense WiFi Detectors

New Around Here
Hey guys new here but this seems to be the collaboration forum for smart network guys lol - sorry for the long post!

I'm not a network guy, only infrastructure, but anyway I bought the 16000 and set it up with a 3 node Asus Zen XD4 AiMesh. It's all working good, I created an IoT network as I have a handful of IoT devices. Every IoT device I have connects to the IoT network with no issues except these X-Sense sensors. Not sure if anyone has any experience or if there's some setting I'm missing but I first tried to change the WiFi, it finds the new network says its changed and then when I go back into the device, its still on the old network (which doesn't exist anymore btw) and still using the old IP.

I removed the device and then tried re-adding it. Scanning their QR codes don't work at all as they just time out and when I manually enter it in the app, it says connected to device, connected to wifi and then when reaching out to their cloud server it never says successful yet it adds the device. Then it shows the device as offline with no wifi settings saved. These devices only turn on wifi once every 11 hours unless it detects something. These are the SC07's. I also have these SC01s which are mini smoke detectors and these things don't connect at all and never get added.

I actually contacted their support and they are baffled as well. I also tried to use my phone as a hotspot to eliminate the router as the culprit but its the same thing which makes absolute zero sense to me. I asked support if these devices are a "setup once and never use again" device but they didn't like my joke. They are sending me one unit to test with out of the box but I really can't see never being able to change wifi on these things. One more note, I had a TP-Link AX11000 previously and that's how I got them connected originally but on the regular 2.4 network. Here's my current settings for my 2.4 network - also IoT's are like the only things using this network as all my real devices are using 5g/6g or otherwise hard wired. I also was on stock asus firmware and flashed to merlin to see if it made a difference. Thanks in advance!

I use the GT-AXE16000 as an AiMesh node.

A couple of questions/comments:
  1. What is the firmware version on your GT-AXE16000?
  2. What is your WiFi security set to on the IoT network? If it is WPA2/WPA3, I would suggest switching to WPA2 only. Asus has had some recent issues with WPA2/WPA3 with IoT devices — they have been incrementally issuing patches across their routers, but I haven't seen in for the GT-AXE16000 yet.
  3. Explicit Beamforming can be enabled — it is Universal Beamforming that is known to potentially cause issues.
  4. If you have not, you might want to try @RMerlin's latest beta firmware (3006.102.4_beta3) as it doesn't appear to suffer from issue 2 above.
  5. Have you tried a hardware factory reset for the devices (typically hold reset button for an extended period of time for IoT devices)?

Thanks!

It is on the Merlin latest beta3. Here's my 2g config:

I have tried to factory reset their devices according to their support - strangest reset I have ever seen - quick press of the test button 4 times, then it beeps, then you have to hold it until it beeps, pull out the battery, push the test button a few more times because somehow they stay on for a few seconds without the battery, and then start the pairing the process. These things use bluetooth to connect to your phone, then your phone plugs in the wifi info and basically they do the check in to wifi every 11 hours. If I knew all this crap I would have went with a different brand lol
 
So I heard back from the support group today and they gave me an idea. I initially created my x-sense with one email address. That email was breached so then I changed it within the app. Different email but same account. They were inquiring about this.

So I created a brand account with new email and guess what, it works like its supposed to. So this is on them, thanks for looking at my stuff, much appreciated but I am all good now. :)
 
hint - on the 2.4Ghz band - leave it at the defaults... b/g/n/ax is fine

Only change I would do there is 20MHz only, and consider WPA2 vs WPA2/3...
 
whats odd is after all this hoopla i ended up using chatgpt to redo all of the asus settings and not going to lie, all wifi networks are working flawlessly with the settings it had me put. also fixed a double nat issue as i forgot to update the mac on my arris gateway so all in all a good networking session lol
