As completely new to Arduino I'd like to get clarification on what I'm actually purchasing! :)
What I want to achieve: I'm wanting to monitor my home power usage (as seen many times on the internet) but also want to monitor the external temperature. I want to be able to compare the temperature against power usage. For the comparing and database storage etc then I'm 100% spot on with that.
What I "think" I need: 1 x Arduino Ethernet Board 1 x POE module
Am I correct in thinking that with these (with the additional components to monitor power and temp) I can perform the task by powering the board over ethernet but also make calls back to an interface I'd be running locally on the network.
A future modification would be to also track when windows/doors are opened and closed and when the heating in the house turns on etc.
