Shelly 1 doesn't regognize temp add on

Hi everybody.

I have a shelly 1 with installed temp add on with 2 sensors.I test before the installation and both sensors measure temp fine.After installation sensors disappeared from the menu,like no add on at all.Try to reset the device twice with no luck.firmware is 210210720-184522-v1.11.0-g6abd92.e.

Thanks in advance.

Thanks for the reply.I wanted to add sensors away from shelly ,and test it with 30m cable .Worked fine with 0,8°C fault. Yesterday i install it to the electric panel.

Hi all

The fault was the wrong (red on add-on) cable connection.After many retries and factory reset i found it.
