I thought I would share what I learned from my experience with my garage door openers. I had searched for solutions before without luck, so I am posting this here now to hopefully benefit anyone with the same problems. I'll start with some background. Feel free to skip ahead. I have been annoyed with my LiftMaster garage openers since I bought the house. They had always been unreliable and the remote transmitters were very cheaply made. I just thought it was all poor quality. I bought a bluetooth receiver to serve as a relay and I used my phone as a garage door opener. I was content with this solution until I bought a Model S just a few weeks ago. I believed that the three openers were unreliable because of the poor quality of the transmitters. I thought programming the Model S would solve this. It did not. Some research suggested LED lights or other electronics can cause interference. That could be a factor but knowing that does not solve the problem. What I wanted was some kind of garage-standard (HomeLink compatible, preferably) receiver to control the garage door openers using electrical switches (relays). At first I was a little discouraged that I could not easily find such a thing, but I did eventually find exactly what I was hoping for. The solution: I bought a LiftMaster 850LM (receiver module) and a LiftMaster 811LM (remote transmitter). $50 for both and now all three garage doors work great from my Model S. The 850LM supports three openers. Only one transmitter is needed. It can easily be reset for each opener to program the car. The range is great and the antenna can even easily be relocated (it uses an F connector). This is exactly what I was looking for. Another tip: It was a little tedious adding each of the openers. I do not think the list of openers can be re-ordered and the order they are added in does not seem to be consistent. (For me, I noticed that once the new entry was added on top and on another occasion it added the last on the bottom. Strange..) So: I deleted everything. Then I added each entry but aborted programming. This way I could ensure that I was happy with the arrangement in the menu. Then I went back and proceeded to program each existing entry. Is there a way to re-program an entry? Maybe renaming and reprogramming would work too.
