I have Aqara S100 switch connected on L1 with Aqara T1M light. Would like to understand how to control the main light and side light separately. Have tried using wireless button 1&2 for automation but not successful.
I tried using Z1 Pro switch in decoupled mode and able to trigger the main and side light separately. So, the issue shall be the S100 that could not go into decouple mode.
Below is my automation
IF press the Wireless switch Button 1 THEN Turn on/off Main Light Ceiling Light T1M
IF press the Wireless switch Button 2 THEN Turn on/off Secondary light Ceiling Light T1M
My L1 switch is always on mode when I tried above.
Hope to get some help on this. Thanks

Hello, welcome to the forum.
I untied the switch button, and made automations that are done for different combinations of the T1m lamp state. For a quick understanding, I give automation version 1.0

Hi, thank you for your reply on this. When you mention that you untied the switch button, is there mean that the switch only have L & N connected only? L1 Load from the T1M light is disconnected? Thanks for the guide as i am quite new on Aqara product and currently setting up my new home.

Hello, in my version (wall switch without zero) the switch has two buttons L1 and L2. L1 powers T1M. I untied this button (L1) (meaning it works in logical mode) and it controls the lamp turning off. Turning on L1 from automation is done in order to turn on the lamp in case L1 turns off (accidental shutdown from the application, after restoring the industrial network, etc…).
Hi, thanks for your response on this. I guess your one work as it can go into decoupled mode? I have tried another switch (Z1Pro) on decoupled mode and able to control the T1M light separately. My room is currently installed with S100 that do not have this mode, let me try the automation as propose if it works.
