Thermometer Diversion Safe – Functional Outdoor Thermometer with Hidden 1 5/8″ x 7/8″ x 6″ Storage Compartment, 0.2 lbs, Indoor/Outdoor Use

Hiding Something in Plain Sight Works Best When It Actually Does Something

A fake rock is obvious when there are no other rocks around. A fake book stands out on an empty shelf. But a thermometer hanging outside? That’s just a thermometer. Nobody thinks twice about it, especially one that actually gives a temperature reading. This one does — it’s a real, working thermometer that happens to have a slim hidden compartment in the back.

It’s one of the more practical diversion safe ideas because it has a legitimate reason to be where it is. Hang it near a door, on a fence post, or inside a garage and it blends into the environment completely.

Who This Thermometer Diversion Safe Is For

Good fit for anyone who wants a small, discreet stash spot near an entry point — a back door, side gate, or detached garage. If you keep a spare key for a dog walker, house sitter, or family member, this gives you a natural-looking place to leave it without broadcasting what you’re doing.

It’s also handy for people who want quick access to a small amount of emergency cash or a backup key without having to go inside or dig through a bag. Workshop or garage types will appreciate that it fits naturally in those environments and doesn’t look out of place alongside tools and shelves.

Works indoors just as well — a home office, laundry room, or mudroom where a thermometer doesn’t look strange. That flexibility is part of why it’s a solid option.

How It Works

Mount it on a wall, fence, or post the same way you’d hang any outdoor thermometer — it even reads temperature, so it does its job as a thermometer without any pretense. The hidden compartment is accessible from the back, keeping your stored items completely out of view from the front.

The interior runs 6 inches tall and just under an inch wide, which is ideal for a rolled-up bill, a spare key, a folded note with access codes, or a small USB drive. It’s not meant for large items — the narrow profile is what keeps it looking like a thermometer and nothing else.

At 0.2 lbs, it’s light enough to hang with a single screw or nail. The construction feels solid for what it is — nothing flimsy about the shell, and the access mechanism is simple enough that you’re not fumbling with it when you need it.

Practical Details

Interior dimensions: 1 5/8″ x 7/8″ x 6″. Weight: 0.2 lbs. Suitable for indoor and outdoor use. Mounts easily with a nail or screw. No batteries required — it’s a standard fluid thermometer. No combination or key lock — security relies on concealment. A simple, no-fuss option that requires no special setup.

If it’s hanging on the wall doing its job as a thermometer, nobody’s going to look twice — which is exactly how a good diversion safe is supposed to work.
