The new Shelly device is not detected

I have installed Home Assistant in a Docker container on my Synology DS719+. After the installation, it detected most of my devices directly, including the Shelly devices. Among them is a Shelly DW2 sensor for the door.

I have since bought another DW2 sensor for another door. Although the device can be successfully found and used in my Shelly app, this device shows up as a name but does not contain any devices or entities.

When I click on the Configure button (above), I only get the following error message:

The configuration flow could not be loaded: {“message”: “Invalid flow specified”}

can anyone help me?

I am having the same issue. Did you ever find a resolution?
