OK… I’ve just pushed v4.0.4 into the wild (https://usage-monitoring.com/installv4.php). In addition to a number of bug fixes, this release finally includes a way to define rules which will prevent certain devices from accessing the web - i.e., you can say that your children’s devices cannot access the web between 10PM and 7AM on school nights and 11:30PM and 9AM on weekends, etc.
See https://usage-monitoring.com/current/SetAccessRestrictions.php for a working example of how to manage the restrictions.
NB - to use this feature on your router, you will have to upgrade to v4.0.4 and enable the database integration options (which is a new prompt in the setup script)
I’m really keen to hear feedback on this new feature. I’ve been running it on my router for a while now and everything seems to work well.
One caveat however, be careful how you define your rules as you could accidentally block all devices on your network.
As always, your feedback is appreciated!
