Why do you have to log in to TP-Link servers in China in order to use any Wi-Fi mesh units from TP-Link? Wi-Fi mesh units are situated in the local area network (LAN) of the user, so there isn't a need to track usage or access. Is TP-Link spying on its customers?! Asus Wi-Fi mesh units don't need a sign in account to work; TP-Link should follow this approach. I guess I'll need Wireshark to log what my TP-Link's Deco units are doing everyday- like "phone home" to Chinese servers overseas.
