While an expanded temp range might be useful, it wouldn’t be practical.
The batteries would drain incredibly fast in a freezer and they would not be effective. Battery operated Gagets do not like sub-freezing temps. This is why most IoT Freezer Temp Sensors are outside with a wired probe running inside.

After making the suggestion to Wyze to improve the climate sensor I found the Govee Wi-Fi Thermo-Hygrometer battery operate sensor works perfect for my freezers. It has been 8 months since I installed the Govee sensors. My freezers maintain a -10 to -15 f temperature and I have not had to change the batteries yet. I just checked and the sensors report about 50% battery remaining.
I think the reason the Govee performs so well is their use of the venerable AAA battery rather than the CR2450, which spec should go down to -4F, but apparently doesn’t.
Just purchased the Govee thermometers which use the venerable AAA battery instead of the CR2450, which spec states should go down to -4F, but apparently doesn’t. We’ll see how they do…
Add me to the list of those who would like to see a weatherproof WYZE temp sensor with a wider range and possibly with a separate probe for freezers or liquids. The description mentions “monitoring attics” but 104°F is not hot enough for most attics.
I’d also like to see WYZE sensors that react to a “dry contact” (zero voltage) opening or closure …should be easy to modify the door contact sensor to do that…or that provide a low voltage low amperage contact that closes or opens upon signal from WYZE app or devices.
