Same here,
I get "“The provided Credentails are not valid” when I try to add my Deco x20 units.
@MathiasT IS it possible to add also the Omada devices to this app ?
Anything you can suggest? Do you know whats going on?
I get the warning “flow card not registered"
It used to work, but recently no more.
Anything I can try (already restarted both homey and the app)
Logged out and can now no longer long in: " the provided credentials are not valid”

Maybe this APP is not being further developed anymore? @MathiasT are you still involved or stopped working on the app? Please inform us

Hi, I (I should say AI) have fixed issues with login and now it works on my BE65 routers. Also created Pull request for @MathiasT . If you are interested you can run my version PechJiri/Deco at fix-errors (install it from terminal).
Can you tell me how to install from terminal? @Jiri_Pech
Or just use chat GPT/Gemini/Claude 
It will give you right command line prompts and guide you through…

@Jiri_Pech doesn’t work for me though
Oh dear! The app has been working OK for me, but doesn’t see one of my Deco’s (X10). So I came here to see if there is a solution. But now I find that the app is probably ‘abandon-ware’. Such a shame. And for me life is too short to fiddle about with terminal etc. I didn’t buy easy-to-use Homey for this!
Hi
I’m facing the same issue with installing the APP to my HomeyPro.
When adding it you should give the log in data and I tried it all as described in the APP description and double checked my password in the TP-Link app on my phone as used for the DECO but I simply cant get it right.
I’m using the web interface for Homey pro.
It is a silly question to take up time with I know…

Hej Mathias, happy to see you here! 
I am running X50-5G, with X50-PoE as satellite units. The Deco Homey app stopped working for me after doing a firmware update on the Deco devices on October 15th. The X50-5G is running fw 1.3.1 build 20250918 rel 49303.
My Deco’s X50-PoE are running Firmware Version: 1.5.0 Build 20250619 Rel. 69357 and when trying to add my deco’s I now get the error message
“Timeout after 10000ms”
Any advice?
