Anyone have any suggestions on how to pair my Aeotec HEM Gen 5? It used to be paired with my Smartthings setup, but apparently it disconnected from the HUB. I am trying to re-pair with no success. If my memory serves me correctly, when I first originally tried pairing to the system I had a hard time. For the life of me, I cant remember. I tried following the instructions in the manual, but no luck so far.
