Good day,
connect the device to the network according to the diagram.
The diod is on on the device, the web is working at the ip address. Visible from the app. Pressing the button ( in app or web) - triggers inside the relay (for an external contactor)
But! There is no data, not only is there no consumption data, there is no voltage data!
I would be glad to any recommendations.
Thanks in advance!
Hi and welcome to the forum. 
Can you upload a picture of your shelly.
So, we can seem how it's wired.

sorry for english
This seems to be good.
Please have a look on this german thread of me.
Use google translate for your understanding. 
Every point is importent and only you can check this points local.
the problem with consumption - we can still check many times, but as far as I understand, if you connect it to only 1 phase - it should still show the voltage in the network, but this data is not there either! that is, not only the load, but also information about the voltage in the network.
I read that topic with the help of a translator, and I understand what they are writing about. but this, alas, will not help solve.
I wrote to the support - so far there is silence.
