Data Usage

Does anyone know how much data the MyQ Internet Gateway uses a month?  I have limited data at my house and do not want to use a lot up.  Thanks in advance!

Very very minimum couldn't really register the amount maybe no less than 1-2mb per month and no more than 10-20mb/month. Can't see any limited use accounts running out with this

It actually uses more data than you'd think, due to the manner in which the connectivity between the device and the Chamberlain server is established & maintained. Admittedly, it's still only about 10.5 MB per-month.

Since firewalls typically allow all connections outbound, and only allow traffic than is manually/explicitly defined (generally via port forwarding), there are really only two ways to make it work:

1) The most technically efficient manner is through port forwarding. These products are marketed commercially, with an intended audience of the average homeowner. Although port forwarding isn't a terribly complex topic, it is unfamiliar ground to a majority of the populace. The associated costs to the manufacturer (and frustration experienced the the average consumer) makes this an unappealing proposition, despite being more data efficient.

2) The second way, which eliminates the need for port forwarding, is to have the device initiate the connection, so that the firewall allows it by default. The problem, however, is that these connections quickly "expire" unless data is constantly passed through them to keep them "alive." To keep these connections alive, the MyQ system uses a equivalent of a digital "heartbeat." About every 10 seconds, a tiny bit of data is sent from the device to the MyQ server, and the MyQ server responds...similar to the old Verizon commercials -  with the device asking the server "Can you hear me now?" and the server responding with "Yep."

Technically a third way, which basically automates the configuration needed by method 1. It is called UPnP or (Universal Plug and Play), however it is not supported by all routers. Further, there are a lot of security issues with UPnP, and if your router supports it I'd highly recommend disabling it for that reason.

Those little heartbeat signals add up over time. If you look at the raw traffic with a protocol analyzer, you can see that the total traffic every 10 seconds = 40 bytes (20 from device to server, 20 in response).

40 bytes per-heartbeat * 6 heartbeats per-minute * 60 minutes per-hour * 24 hours per-day = 345600 Bytes per-day or 0.3456 MB per-day,. Assuming 30 days in a month, 30 * 0.3456 = 10.368 MB of data per-month of heartbeat traffic.

To that, you also have to add the additional data used each time the door is opened or closed, or the status is checked. 

Using the same methodology, assuming the door is opened & closed twice daily, the additional data usage is about .0005M per-day, or .015M monthly.

You're correct that the commands to raise &/or lower the door use a minimal amount of data, but the heartbeats (technically TCP Keep-Alives) used to maintain the connection use exponentially more.

To the average homeowner with an typical unmetered connection, 10.5MB per-month is nothing.

Depending on how restrictive your data connection is, I guess it could possibly be an issue for some folks.

I would like to add to this post.  About a month and a half ago I upgraded my 3 garage door openers to the MyQ variety.  We have had problems with overnight open garage doors and I like the auto close feature and the apps ability to verify that the garage doors are closed.  This last month however we got a notification from Xfinity our ISP that we were at 90% of our allowed 1 terabyte of data usage for a month.  Apparently they have initiated this cap to control people using residential service for business uses where large amounts of data are used.  Anyway looking back over our last several months of data usage shows that we have at the most 300GB per month.  All of a sudden we are at near 1024GB which of course brings added fees when you go over.  I was able to isolate the Liftmaster/Chamberlain Internet Gateway as the culprit as we were using about 54GB of data per day which has dropped to 9GB per day since I unplugged the device.  I loved using the MyQ as it was working perfectly as I could see what was happening at my house from wherever I was, but this extreme data usage is very upsetting and I won't be able to use the MyQ any more.  Any ideas?

That cant be right at all. that is a boat ton of data...you'd have noticed all your phones and computers would have been slow access the net if the garage door open was using 45GB per day...thats effectly 4mbps of your internet connection being used up by the garage door opener over a 24hr period...I suspect another culprit. My employer who is also my ISP has a datacap of 1TB and my access points measure each wifi connections throughput and bandwith. my MyQ has never consumed more than 100KB in a day which is about 3MB per month. im sure its something in your network causing that not the garage door opener

It is true, I disconnected the internet gateway and my data usage has been in the single digits of gigs each day for the last 4 days in fact with everything attached except the internet gateway the data was only 2 gigs yesterday. I plan on reconnecting it this weekend and watching the data usage again. Do you know if perhaps there is a firmware update or something?

There isn't even a single gb of storage for the gateways to use. Either your gateway is completely messed up or as I suspect something else is amuck here
