Question: is this compatible with the Liftmaster model #8355?
Document: A big waste of money this thing doesnt work. They didnt say what model of Chamberlin it is compatible with.
This transmitter is ONLY compatible with a few models of opener. After following the instructions, in detail, three times, I called the customer assistance. The guy I spoke with was friendly, and helpful. After having me go through the steps a fourth time, he asked the model number of opener in my garage. Then he knew exactly what the problem was, and I was out of luck. They may be working on a firmware upgrade that will allow the gateway to work with older openers.
Would highly recommend to anyone buying a compatible Liftmaster garage door opener.
I can't imagine it costs these guys more to keep my access going than Google spends running my email for me. In today's internet, if $14.95 is your breaking point, you should be looking at marketing.The clincher is that LiftMaster decided to use this MyQ "feature" as a way to sell higher-end openers. I'd have to replace my perfectly good opener with a newer model to even be able to consider using the Internet Gateway.
)But I could not pass such a good deal on this. I got this one along with LiftMaster 888LM Security+ 2.0 MyQ wall control panel and Liftmaster 829LM Garage Door Monitor. I do have a LiftMaster 3800 little bit advanced garage door opener. But mine being older model it did not have MyQ control built into it. (Newer replacement versions do have that built-in option). So I had to buy wall control panel along with gateway.
Unfortunately, the insteon sensor wasn't compatible with the new liftmaster. I would have returned it that day, but since they had the myQ I decided to stick with it. The problem I also had with it, when it worked was there was a long delay 5-10 seconds on whether the garage door was opened or closed. Unlike the insteon garage door sensor which only took a second to register.I'm very disappointed with this product offering and would never recommend anyone getting this product.
The item arrived in perfect, new condition and shipping was very fast and efficient from Open Door Discount Remotes. Would recommend them highly. Now I'm able to open and close my door from anywhere in the world using my iPhone app. Liftmaster also has several YouTube how-to videos on installing this device and the wall switch, if needed. Check with them to see if your existing opener is compatible with the MyQ technology. Mine was, indicated by its purple "Learn" button.
Purchased this for my Chamberlain garage door opener (yes, the lift master model works just the same). Quick setup and works flawlessly!
Took me a matter of minutes to create an account at mychaimberlain.com, connect the 828LM to my router, download the iPhone app and &#34;learn&#34; the opener (model 8550) in the application. Now my iPhone can open and close the door. Just what I was expecting.
I just wanted to confirm that this works great with a Chamberlain MyQ ready garage door opener. Not sure what model Chamberlain I own but I bought it from Lowes last year thinking it was going to be ready to go with remote access out of the box. Turns out it was only MyQ 'ready' - has the MyQ symbol on the opener - and didn't include the gateway itself.
Answer: yes
