The Shelly 1L is supported [by the current test version of the app](https://homey.app/en-gb/app/cloud.shelly/Shelly/test/), which only works on the experimental v5 firmware for now. So if you don’t want to install that firmware, you have to wait for it to become stable. Nobody knows when that is. ---

If I use Homey Pro only for 2 zigbee devices and 5 z-wave, is it ok to risk and upgrade to 5? ---

I don’t think anyone can definitively answer that question: most people don’t have any issues with v5, some people have massive issues with it (to the extend that they have to send their Homey back to Athom because it won’t boot). So there’s always a risk involved in upgrading.
