RE: Forget Me Not - 3 - Getting over the RF range

Hello Kimmo,

I've thought along the same lines in terms of extending the reach of sensors. I'm using MQTT for a lot for my sensor network. In fact, my Arduino sensors indirectly report to OpenHAB via MQTT. For me, rather than being concerned about extending incoming data, I was focused on extending outgoing actions - instead of using multiple RPi's as data relays for incoming sensors, I'm using multiple RPi to perform OpenHAB audio alarming in multiple locations. The "remote" RPi run pretty much the same OpenHAB application as the master, but the master holds the MQTT server, and the remote RPi subscribe to the master's MQTT server.

MQTT should work across the internet too. It's designed to be used or simple sensor data. One of my blog posts gives an example with an apartment complex.

I wound up making a simple test with the Launchpad and can now confirm that everything the EnOcean Pi -module seems to need is 3.3v, ground and serial.

The pin order is shown on the image below. Note: 3.3v is on the otherside compared to the other pins, double check when connecting!
