Wireless 2-sensor fridge thermometer?
Does anybody have recommendations? Amazon mostly have one design that everybody is cloning shamelessly. Prices start from $17 and I am not sure whether $25 one would be any better. Huge 4x4 inch moni...

Any remote sensor which uses a battery, wireless AND is in a COLD place can be problematic.
Standard "dry cells" hate low temperatures and with temps of 45F or less they will live very short lives.
Found that out with a Digital T-stat for my garage furnace. Only heat the garage when I am planning to work in it, gets below 32F often during the winter.. More than once had to replace the batteries in that T-stat within a month during the winter before I got smart and ditched the batteries for a separate power supply..
You could try Lithium non rechargeable batteries for low temp use, may work better..
Also have a wireless remote "weather station" with wind speed, direction outdoor humidity.. Yeah, batteries often fail faster during extreme low winter time temps and changing the batteries requires standing on your head to resync the remote to inside unit.. Not to mention, the wireless portion is flaky at best, typically loses connection when there is a weather event and if lost too long a resync is in order again..
For fridge/freezer applications, I prefer the wired route, much more reliable, cheap and effective and keeps the battery outside of the cold of the fridge.. Very easy to slip the wire between the door gasket..
Keep in mind, you will be reading the AIR temps inside the fridge, may not reflect the actual overall FOOD temps as they slowly vary in temps compared to the change in air temps.
