You can have up to 4 Sky Q mini boxes. However with the Sky Q 1TB main box you can only watch on one of the mini boxes at the same time as the main box, with the 2TB option you can watch on the main box and 2 minis at the same time, while viewing different channels on each of them.
The way Sky have worded there sales page for Sky Q, it can be confusing to know how many Sky Q minis you can have, and how many you can watch at the same time.
Below I've tried my best to clear this question up for you.
After reading this article you should have a better idea on how many minis you can have, and how many TVs you can watch them on at the same time.
Remember: Sky Q has an option of a 1tb or 2tb main box option.
There is now a newer Sky Q 1TB Ultra HD box. The difference in regards to how many minis you can have is between the standard 1TB main box and this one is that the newer Ultra HD box allows you to watch on the main box and two of the minis at the same time, instead of just one of the minis like the original 1TB box.
Sky Q Main Box
The main Sky Q box is the one that needs to be connected to the satellite dish. You can think of it as the central control hub. Without this nothing else works.
However this main box comes with two options.
1. Option 1: A 1TB (terabyte) option.
2. Option 2: A 2TB (terabyte) option.
The boxes look exactly the same, the difference is internally with the 2tb basically having more storage space.
Now there are a few benefits in having the one with the extra space, but for this article we're only going to look at the one that relates to how many Sky Q mini boxes you can have with both options.
Now this is were it can get slightly confusing.
Basically, with the 1tb option you can have 4 mini boxes, and with the 2tb option you can have 4 mini boxes max.
But here is were the differences come in..
With the 1tb main box you can only watch Sky Q on the main box and 1 Sky Q mini box at the same time (2 total). So for example if you're watching ITV on the main box, someone else will be able to watch Sky 1 on one of the mini boxes.
If you try to watch sky on a second mini box it will ask you to turn off one of the others first.
With the 2tb main box you can only watch Sky Q on the main box and 2 Sky Q mini boxes (3 total) at the same time.
If you try to watch on the third mini box again it will ask you to turn off one of the other ones first.
So to clarify with the 1tb main box you can have 4 minis but only watch on the main box and one mini at a time, and with the 2tb option you can watch on the main box and only 2 of the minis at the same time.
Sky Q Mini Box
These you can think of as the little stations that all connect back to the main hub (Sky Q main box).
They even look similar to the main box, with the biggest difference being these are smaller.
These do not need to be connected to a satellite dish. They instead connect wirelessly, and as an added bonus if you have Sky broadband they act as wireless signal extenders.
They also do not come with two different storage options as the main boxes do. No matter if you pick the 1tb or 2tb main box option, the Sky Q mini boxes you get will be exactly the same.
The MAX amount of these you can have is 4, no matter which Sky Q main box option you go with.
The difference being, as explained above, with the 1tb main box you can only watch on the main box and one mini at the same time, and with the 2tb option you can watch on the main box and two of the minis at the same time.
But you can still only get a max of 4 with both options.
Sky Q Multiscreen
This is an add on package, similar to say a 'sports' package that you will need to pay an additional monthly fee for, as of writing this the cost is an extra £12 per month.
What the Multiscreen package does is let's you actually get the Sky Q channels that you're already paying for on your main box, to work on the minis.
As an example lets say you're paying £35 a month to get the channels you've got on your main box, to get them same channels on your minis you'll pay an extra £12 a month on top, making your new monthly bill £47 a month.
If you don't get the Multiscreen package, none of the minis will work. So keep that in mind.
The monthly fee is for up to 4 of the minis. So it doesn't matter if you only have 1 mini or 4, the cost will be exactly the same.
What If I Want TO Watch On More TVs
If you want to watch Sky Q on more TVs unfortunately this is not an option.
If you are already watching Sky Q on the max allowed of TVs and try to watch on another mini over the limit, you will get an error message and be asked to turn off another mini first, before you can continue.
What you can do though, with Sky Go Extra, which you will get with Sky Q multiscreen included, is stream and download content on up to 4 mobile or tablet devices instead.
Maybe not the answer you wanted, but unfortunately atm that is the best option.
Hopefully now I've helped you understand how many Sky Q minis you can have with both the 1tb and 2tb boxes, how many you can watch at the same time, and why you'll also need to buy the Multiscreen package for them to work.
