Nah, I pay the $20/year. It's a handy way to block ads and malware on my network, my parents', and my mother in law's. I went through the free 100k or 300k queries in a week or two.
I found them by setting the router to log anything outbound on port 53 since DHCP hands out the router as the DNS server. Our work laptops also ignore the DHCP settings, so I let them use the DNS they want to. But the TV was always hitting 8.8.8.8 even though I triple-checked it is set to use DNS from DHCP. If/when most things start using DNS over HTTPS or TLS, I'm not sure how I'd find them.
I put most IoT stuff on a separate vlan. Sonos and Apple TV are the exceptions - it was too hard to get them to work across VLANs with my phone.
