Excellent work, @Hek. The site is really informative and well constructed. Your code library is also superb. You have made it really easy to get started using Arduino-based sensors and actuators.

I see that you can buy stuff from there (which I plan to, just to support the cause).

I was wondering if you had plans to set up "kits" for specific sensors and the gateway. It would just make purchasing easier. I do see a buying guide, and i will likely go that route for the gateway, but when I start to dive into the sensors It would be cool if I could just go and "buy" everything in one shot to make a "humidity sensor".

The buying guides are nice though and are a good step and this is just an "idea" :)
VeraLite (Live); ISY 994i (Live); Vera 3 (Waiting to replace VeraLite); Vera Edge (Waiting for all the bugs to be fixed); Xuan StackBox (Testing and waiting for more plugins and for it to mature)
Countless z-wave and insteon devices :D

Unfortunately is the ebay-api we're using VERY limited. I agree that it would have been great to have a add-kit-to-ebay-basket-call but  they don't allow this.
So, until we find proper resellers or setup our own shop (which we don't have the manpower to do right now) - the functionality is a bit limited.
At least the affiliate program gives a us few cents when you make a purchase and this will really help us to finance servers and our future crazy plans. Just wait ;)

Excellent work Hek!
Your website made me take the plunge, I've ordered a couple of Arduinos and sensors even tho I'm a terrible programmer and cant tell the difference between watt and volt. Hopefully your easy to follow instructions will guide me so that I'm able to pull through.
I'm really looking forward to see the future of your initiative and plan to donate a ?bro or two to show support.   ;)

Holy Toledo!

Great work, and the website design screams 'fun stuff here'

There are some great projects on the website. I am curious if anyone has any feedback on the RF interconnect performance. It looks like the devices are using the ISM band at 2.4GHz. This will be a completely separate network from the Z-Wave and will not be meshed. Therefore, devices further away from the central receiver will be susceptible to range issues.

As an aside, I looked on the Nordic Semiconductor website and noticed they have a transceiver for the sub 1GHz ISM band which has sensitivity of -100 dbM. http://www.nordicsemi.com/eng/Products/Sub-1-GHz-RF/nRF9E5 The best sensitivity for the 2.4 GHz transceiver is -94dBm (at 250 Kbps). The 6 dB improvement of the sub 1 GHz chip translates into 4 times improvement of the distance in range versus the 2.4GHz device.

Any node can act as a relay back to the gateway so range, has not been a problem - http://www.mysensors.org/build/network

Most use an amplified NRF24L01+ for the gateway that purportedly has better range.

I find that the radio/node performance is very responsive for LED light dimming.

Fantastic. Great source for getting started in Arduino and sensors all in one place. Thanks!

This is a general question, I guess this is a good place to post it...

I am looking to use arduino to check the water level on my pool.  I've been testing the Ultrasonic Module HC-SR04 positioned over the skimmer and it has proven to be very accurate and there is plenty of room for the electronics underneath the cover.  I tested the radio too and that seems to work well, it's only a few meters from the gateway.  I also checked to see that water won't splash against the cover when the pool is being used, that's OK too.  Being that the transducers are made out of aluminum, I'll pot the whole thing in silicone (up to the top surface where the little screens are) as I am worried about the corrosive aspect of chlorine.  I'll deal with that with my first life test, I guess.

So, rather than continuously measure the level, I'd like the sensor to wake up once a day at 3:00am every few days and take a measurement.  I'll use Vera to open a valve for a fixed period of time if the distance is greater than (what I now know is about) 18cm.

I know I'll probably need to look into a Real Time Clock, I was just wondering if there was anyone out there doing anything like this already, or is there an easier way to do this.  I like 3:00am because the pool is motionless at that time (unless there is rain, which I can handle that with PLEG).

I may be better off just waking it up once every 30 minutes and taking the reading that fits into say a 1 hour time bracket, but the technical challenge is more fun.

But if you use PLEG ... you can use a continuous sensor ... say once every minute.

Turn on the water if  greater than a certain distance for say 5 minute.
Turn off the water if  less than a certain distance for say 5 minute.
Put a little hysteresis in the settings ...that should handle swimming or any other water motion.

yeah, the only problem with that is that I know how to do it already.  ;D

I bought the 2 RTC's.  I am actually building a clock with the first one.  It is ethernet connected, with LEDs to display time and gives a visual weather forecast, indoor/outdoor temp and email notification.  It is a longish project because it has a lot of work in the housing.

I was looking for something  a bit simpler for the 2nd and I thought the clock would help with the battery life of the sensor.  Probably overkill...

Plus you know PLEG is always the first tool out of the box. ;)

I also listed a more robust and waterproof version of the distance sensor (DYP-ME007Y).

But you can buy a few  HC-SR02 for the same price. :)

thanks.  The three meter cable is nice, too.  I'll see how long my current sensor lasts...

I have a similar situation in that I have a cabin in the woods on the shore of a small pond - about 6,400 hectares with a large hydroelectric dam on one end. The water level fluctuates as the faucet is turned on and off and I want to monitor the water level at the dock over time. If it gets too low, I know I won't be fishing out of my john boat which will be above dry land until the water level rises again. Should have picked a deeper pond.  :)

I bought a Solar Powered 16 LED PIR Motion Sensor Stairway Outdoor Garden Path Wall Light from my favorite shopping mall (http://www.amazon.com/gp/product/B007BZ0IR2/), took out the LED array and connected the 3.3 Pro Mini Arduino circuit to it instead, drilled two holes in the plastic diffuser to hold a US-100 ultrasonic sensor (a bit more expensive, but it is temperature compensating), and used Hek's sketch with a 60 second interval.  It's mounted on the dock, reporting back the distance to the water, and when the 3.7v 800 mAh battery finally gives up the ghost, I'll replace it.

For the $13 USD I spent on the light, I got a solar panel, a Li-Poly battery, a charging circuit with over- and under-charging protection, and a weatherproof project box with mounting bracket, all with two-day shipping thanks to my Prime membership. I had to make a few mods to the circuit in the light (disable the PIR and the day/night sensing), but it works like I want.

Gotta blame it on a Hek. Before he started this, I didn't know how to spell R-Dweeno, let alone how to build electronic circuits and program micro-controllers. This is way too much fun.
