Freezer temp alarms

Does anyone have any recommendations on a temperature monitor for a deep freezer?

I was looking for one that works on WiFi and would alert me on my phone, but I didn't see any legit ones.
The best tip I've seen is to put a penny or something in a water bottle and freeze it one way. Then turn the bottle the other way in the freezer. If your freezer ever de-thaws, you will know by looking at that bottle. It won't save your food, but it will save you from eating spoiled food.

That's what I was hoping to find. I'm just worried that my old freezer may croak and I wouldn't know until way to late. It's out in my shop.

Take a look at Vaisala. I did some work for a pharmaceutical company 7 or 8 years ago and they needed temp loggers/alarms on their refrigeration and freezer units. We ended up installing Veriteq loggers (since bought out by Vaisala). The units were very precise and could be set to send out alerts by email and/or text message if temperatures went above or below a defined threshold.

I like these LINK, and they aren't bad at all and wirelessly alert you. I would be more worried about a five year old freezer with fans and electronic control, than a 25 year old manual defrost freezer.
As long as the freon line doesn't just rupture, it should keep going and going.
Freezer temp alarms and water alarms are great items to have that no one seems to ever buy.

I built a prototype with an arduino that would alert me if there was an issue, but I figured it would cost too much to make in mass.
I really wanted something that would email or text the repair company to a problem, as i waranty everything i touch for 6 months to a year and I like to stay on top of it.
The worst failure I ever had was a fisherman had us repair his freezer, and then in failed again two months later and Both I and my tech were out of town, so I could only offer to pay for the repair. He wanted reimbursement for spoiled food, but I don't do that. I felt horrible about it, still do. I get the most service requests the three to four weeks a year i take off.

Thanks for the rec My only worry is the range. As I said the freezer is in the shop which is 15-20 yards from the house.
That old freezer should go forever as you said. Will I ever need to add freon to it?

Coach I just looked I have an Accu-Rite. It has 2 sensors. 1 is in my utility room and 1 is outside. I have the monitor on the side of ice box. I look at it in the AM when I get a shot of water before I head off to the office. They range from -2 to +10 degrees normally if it's above 20 I have it set for the alarm to go off. I think the range on the monitor is 300'.

Chaney Instrument 00985 Wireless Refrigerator Freezer Thermometer Alarm Set
Try this on Amazon. Remote controlled but not to phone. Alarm isn't loud but you can install the receiver inside where you see it every day and once you get used to looking at it, it becomes 2nd nature. About $30 bucks. Worth a look.

It's a sealed system so you shouldn't. The big issue is connections where copper goes to steel or aluminum. You get different rates of expansion. Sometimes you develop a miniscule leak. On paper the only repair is remove freon to replace the component where the leak is, pull a vacuum, fill with Nitrogen twice to boil out moisture, and then pull another vacuum, then refill. If it's pre-1996 you have R-12 which is expensive. If its post 1996 you have r134a which is for sale at Auto Zone. (or an appliance store, but then you need an EPA card) It's expensive to repair.
The other repair is to add leak sealant and top off to you get +5psi on the low side.
That is cheaper and works for older systems no problem.
Likely you won't need a repair for a while, but if you do, this is much more common than a compressor.

Thanks Napoleon, it was made in 1984. It's a Montgomery Ward. It's a beast, but just old.

The build quality is different for modern freezers but they are more energy efficient.
When I was a kid we had a cat "unplug" our chest freezer that was out in our utility room at about Day 2 or 3 of our annual two week August vacation. When we came back, what was left of the side of beef inside was ready to get out and frick you up.
I always tape over the electrical plugs of my refrigerators & freezers from the legacy of that happening to us.

yeah but that SOB is cold! I was born in March of 84 and my freezer was made that month (I checked the serial number) I can't let it go until it dies.This post was edited on 12/28/16 at 8:27 am

bah humbug.
Energy efficiency leads to a higher fail rate.
Old freezers are just a compressor and no fans. His really doesn't use that much power.
