Has anyone had problems with a Chamberlain (not wifi enabled) just giving arrows up and down 3 times error code of faulty door controller when using the Mimolite? I could not find anyone else having this issue or how to resolve it. 
My wall button has an LED push button.
Help!!! 
most Chamberlain devices are incompatible . Sounds like you have a fancy wall controller - it is not a simple tiny 2wire pushbutton that would be compatible with the Mimolite method.
