Freezer temperature monitoring Login/Join

We have a couple of freezers we would like to monitor remotely. The solution we’re looking for would be WiFi-app based - I think. As always, there are a lot of options some better than others.

Anybody have any suggestions? Thanks

This is a project I've been working on, off and on, for quite a while. Let's see what suggestions are offered, Tn226, and perhaps team up on it.

I have some ideas, but not yet the skill.




God bless America.

I have been doing this for about a year with a product called SensorPush.

It uses little Bluetooth sensors that are about an inch and a half square. The battery lasts for a year and is replaceable. It collects data at one minute intervals, and the sensor can also store about two weeks of data, so you don't have to worry about missing data if you aren't around. There's a pretty solid app for viewing the data. It runs in the background on your phone and pulls new data from the sensor whenever a sensor is in range of your phone.

You can use just the sensors standalone and rely on your phone, but if you prefer WiFi, SensorPush makes a WiFi gateway. It's a little box that you plug into the wall, it talks to the sensors over Bluetooth and sends the data over your WiFi and the internet.

The app also lets you set alerts for if temps go outside ranges you specify.

I've been using two WiFi gateways, one at my house and one at my mother's, and four or five of the sensors for about a year.

They aren't specific to freezer use - they cover a wide temperature range. I'm using one to monitor a malfunctioning AC thermostat right now, in addition to the freezers.

I have been very pleased with the system. It is available on Amazon. The WiFi gateway is $100 and the sensors are $50 each.





These are screenshots I took this morning of the overview page of the app and the graph of the sensor data for one sensor.

My company has a number of freezers, cold rooms and even one equipment room which we monitor temperature with a service using a device called a SensaPhone.

The base unit can have up to 12 sensors, and uses WiFi and the public safety cellular network bands in case of power outage.

The base unit was less than $2k

I’m watching this thread with interest, my large freezer died and lost the contents. I thought there was a home security camera software that had temperature and moisture sensor capability.

SensorPush looks like it may be just the ticket. Thanks

The raspberry pi gizmo looks neat but way beyond me

Do you put the sensor devices inside the freezers? Is communication affected by that at all? Or is there a thermocouple "tail" that hangs off the sensor device and runs into the freezer?




God bless America.

No thermocouple on a wire, everything is in the little block.

I have three sensors inside chest freezers and a WiFi gateway in my garage and they don't have any problem connecting.

I have another sensor in a third floor finished attic space. I'm not sure whether it is talking to the gateway in the garage or my phone but the data updates while I'm on the first floor, so the range is very good for a Bluetooth device. I suspect it's using a very low connection speed which helps with range.

I use LaCrosse mobile to monitor my dog kennel and humidor. I have not tried the sensor in my freezer but can't imagine it not working. You set the warning parameters and you get text and emails when you are outside the limits you set.
