Did some additional searching and figured it out. The minimote I purchased (DSA03202 v1) need the firmware upgraded first which makes the lower left unlabeled button the “associate” button. Do a google image search for AEON LABS minimote and you’ll see the difference.
I added the minimote to my home hub although I’m not sure I really needed to do that.
I did six separate associations, exiting association mode after each step.
- Master+Acc1
- Acc1+Master
- Master+Acc2
- Acc2+Master
- Acc1+Acc2
- Acc2+Acc1
