I need to be able to monitor a house at another location which will have heat and electricity, but no Internet. In particular I would need to know if the power should go out this winter. Is there a device which would have its own battery that would connect to Verizon 4G LTE cellular and send something to my phone to let me know that there was a power failure? It could be a text message, or trigger an app, for example. I don't particularly need to have remote cameras or anything too fancy.
