I have an analogue voltage 0-5v that I would like to look via an

a command to toggle a relay contact.
Some sort of widget at the remote end that could be wifi or Ethernet
connected to do the measurement and issue the command.
And an app for the iphone to give the display and touch to work the
relay.
Writing software is not a strength but I'm confident in doing the
interfacing of the analogue voltage and the relay driving.
I dont need this to work over 4G links just when I'm home over wifi in
the same sort of way that I can control my Roberts DAB radio.
Any ideas for this sort of product or even what to google for.
Needlessly I'm not looking to spend much money!

Yes asserting control seems quite straightforward but relaying the
analogue value a bit more involved.
