Shelly EM can't connect to the cloud

    • Autor

    Hello the community,

    I have connected a Shelly EM to my local wifi. The wifi connection and internet access seems to works since I was able to update the device to it's latest fireware (in date of 2022/02/09).

    However, my Shelly device can't connect to the cloud, as shown in the image of the web interface. The cloud is yellow while the wifi is green.

    A possibility : my internet box is blocking some ports required by the shelly, but I wasn't able to find them. Do you know them ?

    Any help to solve this problem is welcome.

    Thanks.

    did you invite your EM into your cloud via the shelly cloud App?

    Hello hbrui,

    no, I wanted to know whether you have included the Shelly EM in the Shelly app or only control it locally? You only talk about the WebUI, but you doesn't say anywhere that you miss it in the app or had problems integrating it.

    You probably wanted to address the thread opener Pierre-Eric Allier. I just wanted to help by pointing out the ports needed for a working cloud connection as he was asking for possibly blocked ports.

    In my installation all shelly devices are on a separate virtual network with it's own SSID and IP range where I only allow web browsing and NTP. All are connected to the shelly cloud, no local management system. For the shelly cloud I had to open forementioned ports in outgoing direction, otherwise no cloud connection could be established. I just had a look at the firewalls livelog to identify needed ports. Range 6000 to 6500 TCP is sufficient. Maybe even less, but this works for sure. I did not open any special UDP ports.
