I have a Chamberlain model 7320 built in 2001 with an orange learn button and it will not connect to the MyQ Smart Garage Hub model MYQ-G0301-D. I have verified that according to the documentation my opener is fully compatible. I have reset the hub several times and gone through the setup process start to finish. I made sure the door sensor provided with the hub is paired and communicating with the hub. I have also wiped out all codes from the opener. The hub successfully connects to my wifi and will appear in my app and my account but when I try to add a device it just spins and spins then says no device added. When I say yes to using a door sensor it immediately pops up an error stating "You have reached the maximum number of doors. Please add an additional hub or remove an existing door" but I do not have any doors/devices added.... I am very frustrated that this process is so complicated. Does anyone have any suggestions?
