It says when you pull up History: "Come back tomorrow to see what your
thermostat has been up to" It has been showing this same message for
several days now. ALL other functions are working and showing OK.
Well it looks like Google finally fixed the history problem. It is back
working as of this morning 07/30; sure took them long enough! Over two
weeks just to fix a simple software glitch. No more Google products for
me.....
