Hi I am also planning to replace 2 way switch with Aqara D1 single fire. I am planning to use same switch for both end, but not sure it will work.

Understand from your point, at one end you did is to put L to Aqara L and L1 to Aqara L1 respectively. And leave L2 alone with tapped.

I am still unsure about another end, did you also put L to L and L1 to L1 and leave L2 alone?

Thanks
