Web app does not show app-specific flow card (trigger with device filter) any more — mobile app does

I’m experiencing an inconsistency between the Homey mobile app and the web app (my.homey.app) when building flows.

Device: Sonoff ZBMINI-R2, paired via the official StyraHem Sweden “Sonoff” app (v1.9.0). Device is correctly on driver ZBMINIR2, Zigbee firmware 1.0.4.

The issue: The trigger card “Kippschalter” (ZBMINIR2:click) — an app-defined trigger card with a device-filter argument (driver_id=ZBMINIR2) — behaves differently depending on the client:

  • Mobile app: The card appears correctly under “When”, and my device is selectable. Works as expected.
  • Web app (my.homey.app): The card does not appear in the “When” picker at all, and no device is shown for it.

What I already ruled out:

  • Not a browser cache issue — the problem persists in a private/incognito window (Safari).
  • Not a device/driver problem — the device is correctly on the ZBMINIR2 driver, and the standard capability cards (On / Off / On for x sec / Off for x sec) show fine in both clients.
  • Not an app problem — the card still fires correctly in an existing Advanced Flow, and the official 1.9.0 store page lists “Kippschalter” for the ZBMINI-R2.

So the card is registered, valid, and working — only the web app’s flow editor fails to display this specific card type (app-defined trigger with a device filter), while the mobile app renders it without problems.

Question: Is this a known limitation/bug of the web app when rendering app-level flow cards that use a device-filter argument? Why did I see the if (WENN) card in the web interface some time ago and now it is gone?

Homey Pro, Sonoff app version 1.9.0 from StyraHem Sweden.

Note: It was working before. Otherwise I would not have been able to generate an advanced flow.

As I am a new user, I can unfortunately not add pictures.

The app specific Flow cards still work here, so it’s not an issue with the web app.

Note that some other users have also reported missing Flow cards for Sonoff devices, so it seems like an issue specific to Sonoff
