My spouse’s device is on a pihole exclusion list. Can you not do this with AdGuard?
My own devices are covered, I definitely want full filtering even when not at home and my devices are completely hackable, but I'm wondering if such a tool would be a convenience for other people using the network in particular with less hackable devices, and people likely to use my network are likely totally uninterested in ads, but I don't want this to be a pain.
Apple’s Private Relay also does not work behind a pihole.
