Liftmaster 855lm Chamberlain OEM Homelink Compatibility Bridge

This review is for the sake of the lovers of older model cars that were equipped with homelink. I have a 2009 vintage BMW. Current home was built in 2021 with MyQ WiFi garage door openers (x2). I tried every combination of Jeeeny, LiftServant, Dehomepot and aftermarket transmitters and even stand alone receivers to "Train" my old BMW to work with the new openers but they all failed. Yes yes, even when I got the independent receivers to click acknowledgement of receiving a signal, the MyQ openers would not respond to the hardwire connections. They have become too smart. Last ditch try was to get this Homelink Compatibility bridge. well what do you know, It works! Not only does it work, the single unit works on all 3 doors. Just have to train each homelink button separately using the same "trainer" remote and link each button in the car to each door. Yes, no confusion, no button one closes door 2 while opening door 1. It just makes homelink in the old BMW work the way it used to. I got 3 garage doors to work, I do not know how many would max it out. But it does seem to be locked to that trainer remote that comes as a set. It won't respond when I tried to train the old homelink with a different (old) remote with matching frequency. The car will take the programming, but the bridge will not respond. Must clear all other old learned remotes from the car first before it correctly accept the new training. Works as claimed and yes, can confirm that one bridge unit operates 3 separate MyQ WiFi garage door openers.

I have 2 cars with older Homelink systems built in that will not speak to my modern garage door heads. So I bought this product and voila now both cars open the garage doors. What's nice is that I can set up each garage door for any button. So both cars can open both doors individually. The training is no different than how you set up your garage door opener now: use the provided new remote to train the car, press the train button on the garage door head and press the button in the car you just trained. The head learns the code magically via this product and the garage door opens.

no issues with the device, and was straight forward for compatibility with my car

I could not get my garage door to sync with the home link in the car. (I am not new to home link and have used it successfully many times with numerous garage door openers.) This compatibility bridge solved the connectivity problem. It acts as a "go between" that receives the signal from the car's home link, and sends it to the receiver on the door opener. For lack of a better analogy, the home link in the car could not "talk" directly to the door opener without this device to "translate" the signal. It was easy to install (just plug it in), sync the units and you are done.

Got this so I could operate our Chamberlain garage door with our homelink in our 2011 Nissan Murano, works as it should, extra expense but works....
