I have F6 that I wear 99% of the time. Every now and then I want to wear my dress watch to a wedding or formal event, but don't want to lose my steps and other info like body battery. TrueUp with something like the vivosmart 4 looked like a solution, until I learned it doesn't sync body battery. I thought then of removing the straps from my F6 and keeping it in my pocker, and wearing my Polar OH1 HRM, but you can only record on external HRM during an activity. I am thinking of creating an "Other" activity named something like "Dress Watch", putting F6 in my front pocket and OH1 on my arm and just running that activity all day/night to record HR metrics through the OH1 and step metrics through the F6, then putting the F6 back on for sleep.
My Question: does this seem like a feasible workaround, and anything unexpected you think I might encounter that would undermine the objectives?
