I think you should try again to play with your magnetic switch. Here is some help: http://en.wikipedia.org/wiki/Reed_switch

My main phone is an iPhone but of course Notifon is compatible with Android and Windows Phone. For now PushingBox require a Google account, I plan to do a lot of development to make PushingBox even better. So don't worry, you can be a customer ;)

Of course the Node can trigger two states. So you know when it's open or closed. You can set a different message for each state.

Simple, when you open your door, the Node wakes up during 40ms, transmits at 40mA to the Hub and goes back to sleep consuming less than 1uA. You can calculate the battery life yourself: http://oregonembedded.com/batterycalc.htm

You can't build a mesh network with sensors on idle mode.

The key is to get notifications when you're away. BLE don't have a good range (about 10 meters). ZigBee is more like Wifi (about 50/100 meters).

That's the point, I think I launched the campaign too soon. I didn't had a good press coverage on the launch day. One week later, I got answers from Mashable and Techcrunch reporters, they seemed very interested by Notifon, until I sent them the campaign link (with only 3% of the financial goal reached).

Thank you, I wanted the video short and demonstrative

Thanks for the reply. This kind of price can be reach using Bluetooth Low Energy. Those chips are really cheap but as you might know, the range is too low.

Exactly, for Notifon the transmit time is 40ms. That's why it can run on a small and sexy coin battery (CR2032).

I found him on elance.com

Thanks for those good recommendations, I think you're so right with the "notifying object" words! I think the Indiegogo page is better, I'll merge it with the main website.

Thanks, Z-Wave is also a good technology but I hate the "association" part, when you need to be at least 3 feets from the Hub. I don't think Z-Wave will survive in the next 5 years. Look at Philips Hue, they also chose ZigBee.

I know, it's all about the battery life (about years). The ZigBee chip require only 40mA in transmit and less than 1uA on idle mode... You can't do the same with a WiFi chip, ask Spark... Also, with Hub/Node there is no "association" need like entering the WPA key. It's all automatic

I use a technology called ZigBee. It's a wireless protocol made for Internet of Things devices. This part represent about 60% of the production cost. This chip is expensive but gives years of battery life. Curious about what price did you expected?

In fact there are more details on the Indiegogo page. Can you take a look and tell me if I have to add some details? (http://www.indiegogo.com/projects/notifon-the-notifying-obje...)

The best way is to found a freelancer in China. I used elance.com

Thank you. In fact, I haven't yet launch the mass production. I'm running a crowdfunding campaign on Indiegogo to have at least 400 preorders. As I have done a lot myself, I didn't had to invest so much. The only part that was done outside is the design of the plastic enclosure. I found a good designer in china, it cost me only 700$ for both Node and Hub with 3D printed prototype. In total, I think I spent about 1500$. I had to buy an oscilloscope, some componants and others tools...

me too.
