The rain sensor isn’t made available as a separate sensor. But I believe the window reports a condition when it rains. I can’t remember how the app shows the condition as I don’t have anything with that and I’m not in a place to see the code. I seem to remember it is something like derogation mode. ---

Hi everyone! I’ve read through the entire thread and I’m in a similar situation. I’d like to control a Velux SML electric shutter (24V) via Homey. I’m not afraid of a bit of soldering, but I’m not entirely sure what goes where. I’d like to control it using a Shelly PM 2 relay in shutter mode. Where exactly should I solder or connect the wires? Am I right in thinking this is doable? Thanks a lot for any help! ![IMG_9241](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/d/bd2bc8f74bb330d7bee25583902d47983c6f14ed.jpeg) ![IMG_9239](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/d/7de9e7548b822d6a3e15c55e3bf652ed633aadf3.jpeg) ---

You need a relaymodule with dry contacts, that means contacts that are not connected to one of the power connectors. The point where to solder on, you have to find by measuring what points are connected to the keys that you want to simulate. ---

Thanks for the advice! Since then, I’ve looked into it more thoroughly, and it seems that if I want to avoid soldering, there is a “factory” solution. By adding a Somfy Connectivity Kit, which apparently acts as a bridge and is compatible with the Velux shutter. Do you have any experience with this? This is basically the successor to the earlier Connexoon. ---

The connectivity kit will work with the Tahoma and Connexoon app via the cloud. If you want local control (of sorts, as still needs to authentication via the cloud) then the Tahoma box is better but costs more.
