Have had a Xiaomi gateway running fine for about 6 months, then on Monday evening it went offline.

I have tried several things to try and get it back online, but every time when doing the set up via the MiHome app (on IOS) I can connect to it's temporary SSID but it doesn't seem to be able to join my home wireless. My Unifi logs don't show it connecting. Both IOS and Xiaomi are running latest software versions.

Before I classify it as bricked and order another, anyone got any tips that may help with bringing it back to life thanks?

My gateway has been down for a month as the WiFi router I had it connected to died. It was an old one and connected to my main router with a lan cable.
I've also changed phones and therefore reinstalled the Xaiomi app again.

Yesterday I spent an hour or so trying to reset the gateway (which seemed to work) but I also could not get it to connect to my WiFi. It would time out at about 90 percent.

Mine was setup on the China server previously and connected to Home Assistant on my Pi. Only took about 30mins to get it all setup including 5 devices when I first set it up.
Read a few Web sites saying they had to set the time up on a phone access point first to get it to connect to their router

Interestingly I purchased a replacement unit, assuming my current one had died. The new one has the same issue.

I run Ubiquiti WiFi and a Fortigate Firewall and I can't see any issues showing up in the logs of either. As far as I can tell the Xiaomi Gateway's aren't even connecting to the WiFi as it doesn't show as a client and the DHCP monitor doesn't show it as being assigned an IP Address. I am running the latest software versions of code for both of these systems and for the MiHome app on my iPhone.

Like you AceVPD, I have read that people have more luck with setting these up on the Android app, so I'll try and borrow and Android phone/tablet. I tried running an Android emulator on my PC (BlueStacks) but it couldn't discover the gateway, which is probably more to do with the emulator than anything. I will also try taking a gateway to a different location and try to set it up on a different WiFi to try and narrow down where the issue is.

I managed to spend some more time on this last night. I realised that I hadn't tried setting up the Gateways on my old iPhone 5 running IOS 10 and an older version of the MiHome app.

And guess what, it worked!! First time

Once the gateway was on my network I tried using my iPhone 8 running IOS 11 and it would work for a minute or so and then the app would say it can't communicate with the gateway. Force closing the app wouldn't help and I would need to restart my phone to get to work again, but again for only a minute or so. I couldn't set up any automations on the iPhone 8, saying it couldn't save it, but had no problem doing it on the iPhone 5.

So it really looks like the issue is with either newer versions of the MiHome app on IOS or the MiHome app on IOS 11.

If I can be bothered I will think about emailing Xiaomi support to see what they have to say, but I get the feeling that I will most likely be wasting my time.

Guess it is good motivation to move the automations to Home Assistant, though I guess I will still need to use the MiHome app to add devices to the Xiaomi gateway.
