Still raining here. So besides inside cycling I've played with my setup a little. I downloaded a couple training videos to my tablet so no buffering time wasted... and GREAT resolution. And I mounted the computer part of the wireless bicycle computer... right on my trainer stand. That keeps it well within the 2 foot radio distance. The wired computer is connected to the front wheel.
So now if I train (on the trainer) the miles, time, as such data automatically logs on the wireless rear wheel mounted computer. But if I grab the trainer/rain bike to take it outside... the miles and such log on the front wheel mounted computer. No lost data... no duplicated logs.
