We just had our internet router upgraded recently after Vodafone in Germany acquired our internet provider Unitymedia.\n\nSince the upgrade, all our Shelly devices appeared as offline in the Shelly app (iOS). So first I configured the router to have the same SSID name we had before with the same password. In the Vodafone router admin settings I split the 2.4 and 5 GHz SSID because I believe Shelly only support 2.4. However all Shelly devices were still appearing as offline in the Shelly app.\n\nSo alright, start again I thought. So, I deleted all devices, the scenes and as well as room in the Shelly app. I created a new room before I flipped the circuit breaker switch off\/on, did the switch 5 times thingy to start the add device process (got the blink confirmation). The process of adding a new device seems to complete successful, got the green thing from the top. BUT ... no devices are in the app? I tried it a few times now, same result each time??? I even removed all Shelly devices from our Alexa and I removed the Alexa Shelly skill.\n\nWhen looking at the connected devices in the router admin panel I’m guessing that the Shelly devices may actually be connected (they appear as “unknown”) because I can identify (most) other devices that are connected to our WiFi.\n\nWhat do I do? So far I have three Shelly 1 devices and one Shell 2.5 which need reconfiguring.\n\nI hope you experts here can help me out!!
