My one star review has been deleted 5 times now. I complained the the Nest is useless at following the schedule and I wish I'd not bothered getting it. Nest responded saying I should try deleting and re-entering the schedule, I've tried that, still doesn't work. I have read it gets confused if you cut and paste the schedule which is ridiculous, if that feature is buggy, just remove it. So, I have a very expensive but equally unreliable device that needs constant monitoring. Great.
