I’m trying to add an 828LM and 888LM to my Alarm.com account. I can add the 828LM gateway to my account with no problem. But when I try to add the 888LM device to the gateway it never shows up on my Alarm.com account. Everything appears to work on the Liftmaster devices. I put the gateway in learn mode from Alarm.com and the gateway’s yellow light comes on. Then I press the learn button twice on the 888LM control panel and the control panel’s red light comes one for a second, the garage door opener lights flash and then both the control panel and gateway lights go back to normal, exactly as I would expect. Then when I click continue on Alarm.com it just spins for a while and finally says no new devices were found.
I tried resetting the 828LM gateway to factory defaults by powering it on with the side reset button pressed but that didn’t help.
What should I do next? Does anything look wrong on my account?
