Airport express (2nd gen) not showing in home app.

Ok, fired-up my 2nd gen AirPort Express and it was "seen" by my iPhone SE to add it as an accessory.

I made sure that:

1. I have both Home and Keychain enabled for my iCloud account.
2. You can't add accessories from a Mac, so I used the iPhone to add my Express.
3. To do so:
   1. Tap on the Home app.
   2. Tap on the plus "+" in the upper-right corner.
   3. Tap on Add Accessory.
   4. Tap on Don't Have a Code or Can't Scan?
   5. My Express showed up on the next screen and I was able to select it.

The new firmware is very buggy. People are finding loads of issues..

If you cannot get it to show up directly you can often access it using manual method..

ie in Airport Utility (not sure what home app you are talking about). Go to top menu, file, configure other.

You will need the Express IP address which you can find from whatever router is handing out IP addresses.

If you are unsure tell us the whole network setup and we can give you more instructions.. once you find it then set its IP to static instead of DHCP which will help to locate it next time.

Thanks for the explanation.. I am a really old foggie.. and NEW does not figure prominently on my equipment list. At current prices I doubt they will ever.

Perhaps some of the other gurus here have a chance to duplicate your setup and see how it works.

You do understand that we can’t discuss issues with beta software here ... correct?

It’s late here at the momen, but first chance I get, I’ll double check from both my iPhone SE (running iOS 12) and my 2014 Mac mini (running Mojave) and let you know if my 2nd gen Express (running 7.8) shows up in the HomeKit.
