I've been interested in augmenting my network with Ethernet and WiFi devices for some time. So, just messing around with an Uno and an Ethernet Shield, I built a device that can (without the RF integration)
-
Control any Vera device through HTTP Commands
-
Can be controlled by VERA luup or any wget style command
-
be a sensor on my network
-
be an independant/agnostic layer with equal footing with My Sensors
-
be dependable
I'm not all the way there yet, but i built a sensor that can talk to my Vera, controlling vera devices and can be controlled by vera.
This is the web page it creates:
this sketch allow you to turn on/off a relay via a webpage or Vera, and control a vera device.
take a look:
