If I have two Garage doors units, I need to buy two 888LM devices and one internet gateway device correct?

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.

Correct. You need one 888LM to replace each old opener button and you only need one gateway to plug into your router. They will work with any Liftmaster or Chamberlain opener 1998 or newer. The only difference between the Chamberlain and Liftmaster controllers is the nameplate, so buy the best price.

You do not need two "MyQ packages" You need 2 control panels, and one gateway. Buy one package and one additional control panel, saves a bit of money. As far as "upgrades" go, couldn't be better. Didn't even have to reprogram the homelink in the cars, (that can always be a hassle) Everything just worked, awesome ! (I'm using them on two LM3800 Jackshaft openers from 2010) As of a few days ago, you can control your doors with the Wink Hub too :)

Correct. That is exactly what I did. Just make sure your model number is listed as compatible on your opener.

There should be a pair of units. The unit with only one Ethernet input should be with the router. The unit with multiple Ethernet inputs should be with the Roamio.

Yes, one would connect to your main router and the other one would need to connect to the other router

You need two units. One attached to the exterior of the building with the internet router/modem , and one on the building you want to have internet/network connectivity. You will also need a router in the 2nd building as the Engenius #2 unit merely receives the signal from building #1 and then pumps that signal via ethernet cable into the router in building #2. You then connect your computers to the building # 2 router either by ethernet or wi-fi in the typical manner. Set antennae #1 to WDS Access point and #2 to WDS bridge and disable dns and dhcp on your #2 router (this can be accomplished easily by setting the router to bridge mode IF it has one). The better quality routers typically have a bridge mode setting. Lastly, do yourself a favor and configure everything "breadboard" style before mounting them. You don't want to be climbing up and down ladders and changing the settings after they are installed. I usually just set everything up on my dining room table and plug everything in and test everything before installation. It's a rats nest of wires, and it gets confusing so don't do it when you are tired. One more thing: Engenius tech support is very knowledgable and helpful. I've had very good success working with them.

I am not sure. I have only one opener for my 2 car garage. You may want to call or email Chamberlain directly regarding this question.

You would need one for each as you plug the opener into the receiver. Als the receiver is wired to the opener. It has been a while since i installed mine, but i can't see how one would work for two doors.

Like others have mentioned, there are two devices in the pack. But one is to be connected to the source (like say modem) and another to the laptop/desktop which will communicate through modem to the internet. So if you want to connect more than one laptop/desktop then you can order single additional units or order another pack. You only need one for the modem, additional units just communicate with the same which connects to the modem. In fact I have different model numbers and they still work together.

The short answer is maybe. You do need one per garage door opener unit. I suppose, in theory, you could wire a single receiver in to multiple openers units, but then you're locked into (if there are two) them both opening and closing at the same time.

Yes you will need two Garage Butlers if you have two separate garage door motors.

I have 2 sets of these working all on the same network so yes you should be able to.

No it's not possible paring more than one at the same time, you should discconect the current device if you want to connect a different device.

I have ONE... but I believe two would work... upon startup each end 'scans' for the other end; I would think that if you 'brought up' one link and then the other they would form two non-interfering links. Also be aware that the range of these devices is low... a wall or even serious furniture can impede the signal completely, so it might be possible to just 'aim you way' to mutual non-interference. Hope this helps. BTW: I love mine... it make a super clear and high fidelity connection far better than the WiFi links I tried before buying this.

You would have to buy two and install one with each gate. Check with Amazing Gates 1-800-234-3952. They are very helpful.

821LM can work with two compatible openers, but a second door sensor must be purchased. So, to control three compatible openers, you need two 821LMs and one extra door sensor.

I don' know , you should ask the seller, but yes, it is modem- router in one unit.

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+

You can use either interface interchangeably. You just don't want them both hooked up at the exact same time.
