I've had a quick search and can't see a Post on this topic / project.


I'm looking to build some system (and I know zip about electronics - but I can follow a plan), that alerts me, via a text message, when something is put into my letterbox. 


I've found a few old projects on Instructables, but I was hoping someone in NZ has had success with such a project and could help me through it please.

Rather than pay for SMS, why not use something like pushover?


It's a one off cost for the client (or if you need to support Android and iPhone then 2 x cost, and then there's the web client as well) and then you can send "as many" pushes as you want.  I think it's 7500 a month before you have to buy more.


Sorry I can't help with any of the other stuff, but I use pushover for heaps of stuff and it's really great.

What is doing the detecting? 


The other bits are fairly easy.  Pushover/email etc.


Could use mqttwarn  (which does need a machine with mosquitto server on it - , but if this is the start of playing with home automation that's not a bad idea.


I've just been playing with a Wemos D1  Mini, and using a library called PubSubClient for sending mqtt messages.  Then rather than having to deal with the pushover/smtp/growl apis on an arduino machine, a full size linux machine running mqttwarn is able to splatter any notifications in all sorts of directions.
