Just use the app on your phone?
Yup got that bit but it's more if those actual AP's could operate as wireless bridges to an existing WiFi network (Sky Hub) as various Ubiquiti and Reddit posts mention 'mesh' mode with other Unifi devices/AP's but not specifically bridge to an existing wireless network and differing vendor.
Gut says yes but having just found out with a TP-Link EAP that doesn't support it without Omada, i just wanted to double/triple check before throwing cash down
Sky Q is a nightmare, especially if you throw something like Sonos into the mix which is equally as weird.
It's an absolute pain in the rectum. One box worked with no issue (genuinely no idea why), the others it was a piece of string on how long they stayed up and i tried all the options, tips and tricks here, Reddit and other forums before the moans of "I can't watch X,Y,Z" became too much.
Had the same issue with Draytek gear last year so it's not the UX fault and i quite liked it other than it could do with a smidgen more grunt.
