The same for me, the configuration done manually via the web frontend, then no longer accessible. Whether a short press of the button or a long one, the thing no longer reacts, cannot be reached / addressed. The Shelly DW does not work, it cannot be logged into the network or cloud from the app. To put it mildly, the Shelly DW is rubbish. For some time now, all Shellys can no longer be configured via the app, although they are found, the network settings cannot be transmitted. This is not a product, it is just handicraft stuff!
