Hi all,


Currently I'm plotting the temperature & humidity of the 3 bedrooms in our house on Xively using a selection of Arduino, devDuino & Netduino devices connected using nRF24L01 wireless modules.


The power consumption data feed is coming, the code is finished, I have just got to install the sensor on the main feed from the street but it's mid winter here and it's sleeting outside so I am not in a hurry.


The *duino devices upload sensor data to the Netduino 3 Wifi which is equipped with an nRF24L01 shield from 

Embedded Coolness.  


The Arduino Uno R3 device also uses an Embedded Coolness shield. 


The devDuino V1.3, V2 & V3 devices have on-board nRF24L01 connectivity.


The temperature and humidity sensors are all Silicon Labs Si7005 devices so the results are consistent.


The power consumption monitor is Netduino based and using a devicter Energy Monitoring Shield which I have modified to work with 3v3 Netduino devices. For more detail about how to program the energy monitor shield see these posts about the Nokia 5110 display, nrf24L01 wireless link, and non invasive current sensor algorithm optimisations.


The Netduino 3 Wifi ran for a week without stopping, and would have gone for longer but I had to update the software.


All the configuration is stored on the MicroSD card so a gateway can be configured with MFDeploy and a text editor (I was looking at putting the network settings on the MIcroSD card as well if possible).


Next deployment will be using a Netduino 2 Plus and the new TCP-IP stack
