Gale-Gatekeeper is a security tool that allows you to control devices on your Wifi. Gale-Gatekeeper is a Telegram-based network access control system for OpenWrt routers. When a new device connects to the network via DHCP, the system sends a Telegram notification with interactive Approve/Deny buttons. Devices with static DHCP leases are automatically allowed. Temporary devices require manual approval and have timeout-based access (30 minutes default).

I was so tired of the impossibility to control the wifi devices on my network. My kids used to jump devices from one to another. I also got a host of devices from school which I had no control over. So my kids basically got access to the internet almost 24x7 jumping devices. I have been trying very hard to implement a effort-reward mechanism but it was not working as I had no/almost 0 control over the screen time for my kids.

Netgear R6220 router an AC1200 dual-band router with very impressive specs. It was awarded the best router in 2016 and now in 2019, I still think it is a very good router. It has a 2 core Mediatek MT7621 (MIPS) processor with 128 MB RAM & 128 MB ROM i.e. ample space with some good processing power. Below you can see the impressive specs. BTW: I got this for almost 15 USD which was a steal!
