Please use the support topic next time: [[APP][Pro&Cloud] Shelly](https://community.homey.app/t/app-pro-cloud-shelly/765)

Nothing changed in this functionality in the latest release so it’s probably something else triggered after the update. Do you have a static IP assigned to your Pro 4PM? Did you check the device settings under channels 2-4 to make sure it reflects the correct IP address of the Pro 4PM?

And if that is all correct, could you send me a diagnostic report.

A last resort is to re-pair the device and see if that fixes the issue.
