Hi guys. I would like to automatically turn off wall switches and turn on light in case of smoke detection of Fibaro smoke detector (device id 21). How can I associate Aeotec switch 5 (device id 31), Fibaro wall switch (device id 34), Fibaro dimmer 2 (device id 36) and Neo coolcam wall switch (device id 19)? My plan is: in case of smoke detection Fibaro smoke sensor, Fibaro wall switch turn off, Aeotec and Neo cool am wall switch turn off, Fibaro dimmer S1 turn on. ---

Any reason why you don’t wanna use a flow that does exactly that? ---

Security reasons. In case of fire, Homey may not working. ---

Then Fibaro send a notification to other devices. ---

Anyway, if you wish to do a direct association then that has nothing to do with Homey. You should find the required info in the device manual. ---

You can set the associations in the advance settings of you Fibaro SD. By entering the Node-ID in the corresponding Association Group. (Group 2) ---

Thanks. But I’m not sure how to set “basic command class”? How can I set “basic off” parameter? ---

Take a look on parameter 10,11 and 12. (Fibaro Smoke Detector) ---

I hope i set it correct. When smoke alarm on, send to all associated devices in group 2, command “off”. Right? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/0/60b3042b750b6ef7505129bbeb7105637abecab0.jpeg)
