My garage has two side by side garage doors (Marentec--Synergy brand). Do I need two of these devices?

Only if you need them to operate independently. Your installation techie should be able to resolve the question for you.

I retract my answer and bow to the Butler garage LLC man. Of he says two, then two it is.
1964764
Yes you will need two Garage Butlers if you have two separate garage door motors.

I'd go to Garage door butler's web site and ask that question to know for sure or call a garage door installer. I'm betting there's a way to link the two doors with one opener if you don't mind them both opening at the same time, assuming you have only one garage door opener.

The Simple answer is yes. Assuming that you want both sides to operate independantly of one another.

You get away with one if you get another magnetic switch and series them together. Most any electronic store or alarm store will have what you need. Go to Garagebutler.com and ask them. They probably will sell you what you need and tell you how to do it. Fellow named Frank was really help with a question I hhad.

I suggest you see "installation notes for a two-car garage" here: http://www.amazon.com/review/R2AZZ6GYOCFSGS/ref=cm_cr_pr_perm?ie=UTF8&ASIN;=B0008D6NK0&linkCode;=&nodeID;=&tag;=While per the other answers the 2-laser unit seems to work, I think there are advantages to using two single-laser units instead, stemming from the fact that they can be aimed completely independently of one-another.

Yes you need two for the best result. I have mine running a 1/4 mile apart with no problems.

I believe that is correct. The gateway should work for multiple devices. For full disclosure, I just installed the gateway and the 888lm device at a vacation house, but I only have one garage door.

Yes, you will need one for each device you hook up. I have one at the modem two more. One for each of two tv's. Works great.

Yes. You need the gateway to make this device work. You can add the garage door later. No yearly fees. It's great.

You need to buy 2 of them to fit two. Garage door. Very easy to install by myself.

You will need 2 of them, and a direct line of sight. They are very easy to install however. Just go on YouTube an they have tutorials

I would think just one gateway would be needed since multiple devices can be used with the gateway and each device is registered. Yes on the wall control. LiftMaster 888LM Security+ 2.0 MyQ Wall Control Upgrades Previous Models 1998+

No, you only need one. Please check out this video for more detail. https://www.youtube.com/watch?v=0Fs6v3rvuuk

You don't need to have the same brand of Moca. I have Three 3 types of moca devices and 3 devices all work great together.

It would be best to purchase one for each door so you have independent control of each door. They work great. Mine triggers a welcome home scene if it is after dark.

Yes, you'll need two of them. If you have a coax network in your house (i.e. a bunch of splits and runs to other rooms), you just put one on your modem and one in each room you need one in.

I would call Chamberlain. I would think one internet gateway unit with separate wall controls for each door will allow you to use your current controllers in addition to controlling your garage via an app and the web. Each door would need to be registered under your login ID. I would double check with Chamberlain but I think this is correct.

Will one MDTK keypad open 2 different (side by Side) garage door openers, or will I need to purchase a keypad for each garage door and is this model comparable with the Linear LDO50 garage door opener?

Yes, you will need two of them. You are exactly right one for modem and the other wherever you want. I will say it is better than wireless but don't expect blazing speeds.

You would use the included wall switch. If there is no entry to your garage except for the garage door, then you should buy an external key pad add on to ensure you have access even without a remote.
