I have a large number of the GE Smart Plugs and like you hesitant to put them on a fridge / freezer in case of failure.
However (not that I have done this yet...) it just occured to me that you could monitor the energy usage via the API and once established the typical energy usage, you could program some kind of alert monitor.
I have a small freezer in our garage which is not actually attached to our house, but good enough that the WiFi reaches.
I monitor the energy usage regularly and it would not be too difficult to build upon my java code and fire off some kind of alert when a device stops reporting energy usage.
For instance the small freezer in my garage shows the following consumption:
howard@raspberry:~/java $ ./PlugG.sh
Today:
1 day(s) from: 00:04 on day 349 to 12:29 on day 349 0.149 kWhr consumed via PlugG (13133 secs using power)
Yesterday:
1 day(s) from: 01:03 on day 348 to 23:00 on day 348 0.247 kWhr consumed via PlugG (22185 secs using power)
Past 7 days:
7 day(s) from: 00:02 on day 342 to 23:00 on day 348 2.386 kWhr consumed via PlugG (224117 secs using power)
Past 30 days:
30 day(s) from: 00:00 on day 319 to 23:00 on day 348 9.231 kWhr consumed via PlugG (836581 secs using power)
The java code is on github and runs on linux or Windows. If interested, take a look at:
