I've been using one for a couple years now and although it is keeping my temperature adequately stable, I find it has a weird quirk. It will be at 78 and turned off and then it will suddenly plunge down to 76.4 (for example) turn back on and then climb back up closer to the 78 degree shutoff all within 20 seconds. It's like a brainfart that it then realizes and corrects. Anyone else got weirdness with their inkbird?
