Had one of my freezers die on me.  Didn't loose too much thankfully.

Beings that I have 4 freezers and a refrigerator that I need to monitor.

They are all in the detached Garage, roughly 75' to the center of my house.

I don't have wifi, so that's out.

The alarm ideally would plug in with battery back up.

Do I have any options?

I have two of these monitoring 4 freezers and they work great

I have a couple thermo works nodes.

Never mind.  They arent what you are looking for.

Do you have internet at all?  The Yolink system has a hub that can connect into a router.  The sensors use their own radios to connect to the hub over long distances.  Besides temp sensors they have a bunch of other home automation stuff.

These ones worked for me before I got into Yolink

I only have a wireless Hotspot device, and range is limited. The wifi signal won't go through the stone walls of my house.
