Remote Temperature Monitoring

[frankred]

I am looking for a solution to remotely monitor temperature and/or power for a freezer. It would be great to have an App that could notify if the temperature went out of range or the power went out (ups required on device and modem/router).

I have found that Ubiquiti mFI looks like it would fit the bill well, but Ubiquiti is no longer developing on that product. That makes it seem like a dead end.

Control By Web seems to be another option, but they don't answer their phone or have a way to leave a message [edit: this statement is wrong, I was dialing their fax number]. http://www.controlbyweb.com/products.html

Has anyone found a good solution for this?
Thanks,
John

arduino with a dallas 3 wire temp sensor and an internet connection? you could have it sent out an email. shouldn't be hard to get it to monitor the a/c power as well as if that goes off it should give advance warning of the temp going down, a door sensor could be useful to? it would be easy to have it run a web server to give a/c status and temp as well.

beaglebone black or raspberry pi will take a dallas 1-wire temp sensor output just fine.. you can use Domoticz for data-logging and alerting you of temperature changes.

I have never messed with Arduino stuff. A friend had recommended Particle.io and I told him I was hoping for a finished product...

Having said that, I just watched a video on how to setup a Dallas sensor with an Arduino. It looks easy enough in the video, but I find it is always the ground level processes that surround a task like that which I lack.

I don't know if this company is still around since their website is down, but for temperature/humidity monitoring I've had some luck with devices from PCSensor.com. Their software looks like it was developed two decades ago but it is certainly easier to deal with than raspberry pi or arduino for someone who may not be comfortable with low level electronics or linux.

The most user-friendly option may be something like this, which I can also vouch for being pretty decent: https://www.acurite.com/learn/my-acurite/whats-new

Hey John,

Have look - http://miwsn.com/ This may suit you needs. I have one setup for a water sensor/alarm. No app to date but it emails alerts based on you needs. They are battery operated. I get about a year out of a battery.. The cold will no doubt hamper the battery life but you could wire up an adapter.. It's basic but reliable!

Thanks for bringing these to light. It looks like the Mi-gateway doesn't have sensor capability functions, so the price to entry is $60(gateway) + $30(sensor). Not bad!

Look up info on Raspberry pi for home brewing. The forum I'm part of at homebrewtalk.com has tons of info on it. They go a step further with turning the fridge off/on at various times to maintain temp but a lot of the newer stuff out there allows alerts and a web interface. Its def possible just a matter of finding the right stuff and being comfortable setting it up.

There are a few options depending on what you have available to you. If you have any kind of control system (or have any experience with Arduino or Raspberry Pi) then I would suggest looking into OneWire sensors. They are inexpensive and they work very well.
