I saw that the other day. It is pretty neat and given me a few ideas.
I suppose I was also asking (although not very well worded!) where's a good resource when you want to design and manufacture your own bespoke PCB? Is there a good book anyone can recommend?
@rvendrame
Yeah, I've used datamine previously however I wanted to know if there were any other solutions out there as I want to incorporate building a website into my project too (I'm learning HTML/CSS on the side).
Has anyone had any joy hooking up Initial State with MySensors/VeraLite?
Also, Veralite only has 1 USB port and I'm using that for my gateway so can't log to USB stick at same time.
Hi,
I built a basic temperature sensor node, first on a breadboard and then on a perf board (is that correct terminology?) as per following pic:
Picture of perf board prototype
(I still need to do some of the battery saving tweaks like cutting the LED track and running off 2 x AA via step up regulator).
I plan to make multiple sensors and fit it into some sort of enclosure to mount on walls inside and outside my house so it needs to look relatively 'smart'.
I'm a noob when it comes to electronics so what are my options to make the project more permanent/smaller form factor (e.g. shields, manufactured PCB etc)?

Hi
I've set up various sensor nodes meshing with a serial gateway connected to a Veralite e.g. Temp, humidity, PIR, door sensors etc.
I'd like to be able to save and graph the results over time and automatically push the results to display via a webpage, so I can analyse later and see trends etc.
Like this:
Temp sensor ==> Serial Gateway ==> Raspberry Pi ==> Webpage
I'm thinking I'd need the RPi to act as an Internet gateway (unless I can somehow use the Veralite).
What are the options?
I'm willing to do my homework on this and read up if anyone can point me in the right direction of where to start.

Hi there,
Had some success creating a few temperature and humidity sensors hooked up to my veralite via a serial gateway.
I now want to move on and build an outdoor weather station using multiple sensors connected to one Arduino board. The thing is I'm struggling to understand how I would go about combining the sensor sketches for the various different sensors into one single sketch (e.g. temperature, humidity, rain sensor, barometric pressure etc). I assume its not as simple as copy and pasting sketches together.
Can anyone point me in the direction of some resource that would explain how to go about combining the sketches in this way?
Any help or guidance much appreciated.
Yes that was correct, so your solution has worked perfectly. Thank you.
I also understand where I went wrong now so thank you for point that out. I probably should have figured that out myself if I'd read and understood the code a bit better, but hey ho...
Hi all,
Does anyone know if its possible to calibrate a DHT11 humidity/temperature sensor, specifically the temperature element?
Based on other thermostats and temperature sensors it is reading about 2 degrees C high i.e. 23 deg C instead of 21 deg C.
Alternatively, is there a way I can factor in an adjustment to the sketch so the temperature reported in the Arduino Temp device in Vera UI15 is reported 2 degrees lower?
I've tried amending the code in the sketch as per below but this only changes the values printed to the serial monitor and not the device in Vera.
[code]
Serial.println(temperature - 2.0); // adjusted as reading 2 degrees C higher than room thermostat
[/code]
I'm a noob when it comes to Arduino, programming and Vera so please bear with me...
Setup:

Hi all,
Came across this site a couple of weeks ago after doing some Googling about home automation and Arduino.
Been using Vera Lite (UK) with Z-Wave devices for a couple of years, but got lots of HA projects in mind hence using Arduino.
After a few teething issues I've managed to setup a basic DHT11 sensor and can see the sensors in UI15 using a serial gateway connected to Vera Lite.
Fingers crossed all my other projects go as smoothly! 
Great work Hek!
