Correct way to set alternate DNS for a single MAC/host?

I’ve just finished initial flash and config of OpenWRT and turned up AdGuard home and AdGuard DNS. So far everything except for one device on the network is behaving as expected- my Eufy camera base station. Disabling block lists and white listing via AdGuard isn’t helping it can’t communicate with whatever controls the cloud bit and switching geo location home/away from phones. I’m thinking I need to do two things:

-make a reservation for the MAC - which I did through Luci.

-use alternate DNS and pipe this host through to Google DNS (since I’m fairly certain AdGuard DNS is why the host stopped working). Since I don’t think the gui exposes setting an alternate DNS for this device, I’m going to use putty (for the first time). If I can figure out getting into the command line and getting to the host file…will this work?


config host                                          
         option name 'EufyHomeBase'                       
         option dns '1'                               
         option mac '8C:85:80:94:76:42'               
         option ip '10.0.1.117'                    
         option tag 'altdns' 
 
 config tag 'altdns'                   
         list dhcp_option '6,8.8.8.8,8.8.4.4'

Ah that’s making a little sense. Thanks for the link! So for my situation:


uci set dhcp.@host[-1].name="eufyhomebase"

uci set dhcp.@host[-1].dns='1'

uci set dhcp.@host[-1].mac="8C:85:80:94:76:42"

uci set dhcp.@host[-1].ip="10.0.1.117"

uci commit dhcp

/etc/init.d/dnsmasq restart

AND

Make another DNSmasq instance. Which this page describes but I’m having trouble deciphering since I’ve never really done this sort of thing before. In the example it’s making a guest LAN but I don’t see where the DNS entries/IPs go
