Grill is such a broad term, too. Camping grills, tripod saucer grills, suburban home grills, BBQ grills, home made fire pit with iron grates. Perhaps we’ll see certain types become less popular, but the grill has existed for nearly as long as civilization.
If you’re remote-accessing these resources and can’t always be home to manage the cutover to cellular, I recommend splurging on a Unifi Dream Machine and LTE Backup module. Getting a verizon gateway or similar device won’t properly communicate with your network and has to use it’s own judgement through traffic monitoring to know when to take over DHCP/routing. We (local MSP) just resolved an issue where these devices couldn’t tell between an ISP blip or an outage and so it would wrestle DHCP from the firewall when they still had internet, killing their wireless printers. Unifi LTE communicates with the UDM over a very verbose and reliable protocol. The LTE doesn’t kick on until the FW realizes there’s a problem on the primary WAN.
