I bought a Fenix 6X Pro and a Venu for myself and my wife. As these are somewhat uncomfortable at night, I also got us both a VivoSmart for recording sleep stats.
Switching the active device to get the Pulse Ox readings every night is a pain. Can this be automated somehow? Since we switch devices at night, battery life is irrelevant as the other watch always goes on charge. We don't need to actively track what the Vivosmart is recording at night, so it'd be nice to just have it track the Pulse Ox without any user intervention.
