I have just connected a Shelly 2PM Gen4 to two exterior lamps.
The problem is that I can only turn on both channels at the same time, and ones its tned on it turn off the lamps in 60 seconds.
Two querstions.
How do I enable both channels, independently?
How to prevent that it turn off the lamps?
The Shelly PM2 Gen4, what @andnil84 is referring to, doesn’t support Z-Wave. It supports WLAN, Zigbee, Matter and BT.
The Shelly Wave 2PM does support Z-Wave.
That’s right, but, as @Peter_Kawa already mentioned, neither the topic owner nor you wrote “Wave” anywhere.
The intention of my comment was that it’s important to use the correct product name. No more, no less.
I did not manage it though the Homey app.
So what I did, was to create a Shelly account, download the app, add the 2PM device there, chage it to be a switch instead of controlling a cover.
THEN I added it to Homey, with that shelly app, as a Zigbee device, then tada it works
