Am I doing something wrong. I'm using an Inkbird plugged into an Apex outlet for backup. The Inkbird is set at 77.0 degrees but it seems 1 degree is the smallest temp variance I can set for above and below that value. This allows the temp to drop to 76.0 before turning on heaters, and potentially rise to 78.0 before heaters are shut off. Surely this is too much fluctuation.
