Background: A couple of times I've had my garage freezer defrost. I'm pretty sure it's not failed, just that the door isn't properly shut, so I want to find a simple way to monitor it. I already have some basic wireless energy monitors and I figure a reduction in average usage (eg it failed) or an increase (door open) would be a good place to start.
I've not done anything like this before and I'm thinking about building it around a Pi. But for the "if the energy drops below X or goes above Y for a period of Z then send me an email/text message/other alert" bit I figure I should use something standard.
IFTTT came to mind (never used it, been aware of it for years). Or, if I care about my data, a FOSS alternative (Huginn and Bip.io came up from a Google search).
Anyone here had any experience of anything like this to make a recommendation?
This is intended to be the start of an adventure where I start playing with all sorts of potential triggers and actions so to be honest I'm not so fussed about a specific solution as I am in finding a gateway into something to play with. IoT is something I'd like to experiment with in general, but due to lack of time I really need to be able to get something useful up and running pretty easily that I can then extend when time permits.
