I am trying to integrate a Shelly Pro 3EM as a smart meter into my Avocado 22 Pro system via the FoxCloud 2.0 app. Although the Shelly Pro 3EM can be selected in the app, I get an error message when I try to save the configuration (see screenshot).
Here is what I have already checked:
Both devices are in the same subnet (192.168.178.xxx), the Shelly is reachable via its web interface.
Modbus TCP is enabled on the Shelly on port 502.
Authentication on the Shelly is disabled (no local password).
Shelly Cloud is active and the device is online there.
Firmware of all devices is up to date.
Question:
Has anyone successfully set up this combination (Shelly Pro 3EM + Avocado 22 Pro + FoxCloud 2.0) and can tell me which exact settings are required in the app and/or on the Shelly so that the integration works without errors?
