The H310s work fine in my freezers, and accurately report the temperature as it swings from -10°F to about 4°F. I really needed these to alert me if the temperature rises too high, like to 20°F. But if you set an Alert (Comfort Zone), you can only set the lower limit to -4°F. I have read the explanations of why Tapo only supports to -4°F (-20°C), though the sensor appears to have no problem going to -10°F), but I am getting constant alerts from my H310s as the temperature gets below this limit.

My Feature Request is to allow disabling the Comfort Zone settings for either the upper or lower range. In my case, I would set the upper to 20°F and disable the lower temperature alerts, and the unit would be working great for me.
