Samsung SmartThings app: cannot add washer – “at least one location required” with only “Deny”

Hi,

I’m using a Homey Pro 2026 with the official Samsung SmartThings app.

My Samsung washer is correctly connected to SmartThings:

SmartThings Location: Home

Room: Wasruimte

Device name: Wasmachine Wilderman

The device works fine in the SmartThings app on my phone.

On Homey I do the following:

Go to Devices → + → Samsung SmartThings

Select Washing Machine from the list of device types

Then one of two things happens:

Either I get a black screen and the wizard never continues,

Or I get a message:

“Er is tenminste één locatie benodigd om …”

and the only available button is “Weigeren” (Deny) – there is no way to select a location or accept anything.

What I have already tried:

Restarted the Samsung SmartThings app on Homey

Fully power‑cycled Homey Pro (unplugged for >10 minutes, then booted again)

Restarted my phone

Verified that my SmartThings account and location are correct and that the washer is visible and working in SmartThings

But the problem persists: I cannot get past the “at least one location required” message (with only “Deny”), and I cannot add the washer to Homey.

Could you please check if this is a known issue with the current Samsung SmartThings app on Homey Pro 2026 and SmartThings’ latest changes (locations/permissions), and if there is a workaround or fix?

Thanks in advance.

Do you have a shared SmartThings home? Make sure you have at least the “Full access” permission

Yes, I have…

Sometimes some buttons appear to be invisible.
Try to add the device using my.homey.app instead to see if the screens make more sense.

I use the Smartthings community app by the way.

I experienced something similar.
adding device from SmartThings would hang somewhere in the middle.
Tried it with duckduck browser in many ways. not working. (PC)
Tried it on foirefox browser (phone). Not working.

Opera (PC) finally did the trick.
