Ugh! Just found this string... wish I had seen it earlier. So it's true, I guess. When I lose the Bluetooth connection to the Sous Vide, the timer is lost. It does NOT continue on its own on the device!?! That, in a word, stinks!
I went upstairs today, since the Sous Vide was going to sit for ~90 minutes or more. For 1 minute or less, I lost the connection... and when it came back (and when I finally noticed), the timer was "off". Good thing I remembered the time I dropped the steak in, else I would have lost dinner for everyone!
