Looking to 'group' kids multiple devices and apply both time constraints and weekly data quota

Question

So kid A has 
 MacBook+Android Phone+iPad+Windows Computer+Xbox+3DS+Amazon TV (in my day I just had a soccer ball and was happy).... :) 
 Ignoring that for a second I would ideally like to create some rules which state 
 Access to that group of devices is only available 8-10pm Monday to Friday then 10am-10pm weekends 
 During 1 week there is a maximum download total accross the devices of 100Mb. Kid gets cut off after that 
 Streaming Apps (Netflix/twitch/youtube etc) are limited to SD traffic levels for all users 
 Unless it is me of course - in which case I want 4K streaming of videos (the wife probably gets that as well) 
 Visitors to the house get a set amount of bandwidth - 512kbps 
 In an ideal world I would define the kid A 'group of devices' by either mac address or static IP address. Then there is no login required (not available anyway for all devices). 
 Is this possible? Goal here is to stop kid using machines when they should be doing homework (ignoring phone 4g connection....) and stopping them leaving twitch streaming 1080P for 12hours a day killing my provider data cap. 
 
 It looked like XG would be the way to go due to the user policies verses UTM. This will be a new install though so either would be good.

Tolax, 
 you asked so many questions in one thread. Anyway, have a look at this KB on how to create and apply traffic shaping: 
 https://community.sophos.com/kb/en-us/123061 
 https://community.sophos.com/kb/en-us/123062 
 Access restrictions can be applied inside the policy rules (scheduled time). 
 You can find useful KB from Sophos Community XG section: https://community.sophos.com/kb?TopicId=10218 
 Thanks

John, 
 inside the Web Menu > Surfing Quota you can define the amount of MB and time a device is allowed to consume. Have a look at the online documentation:

HI , 
 Quota Management is Applicable to Client based user , for Clientless you cannot apply the Data transfer and Surfing Quota . But you may add addtional restrictions such as . 
 Application filter : Apply a Schedule on the Streaming Media category and allow it for certain time in a Day or week. 
 Web Filter : Same is applicable but would prefer application filter as Netflix is a App based as well. 
 Internet Access policy on the Clienless user: Allow certain window to allow internet access. Eg between 8PM to 10PM and so . 
 Hope this would help 
 Thanks and regards
