While waiting for Chinese customs to clear our DigiKey/Mouser IC component package (hopefully by Monday!) we placed some small quantity orders of components from local Shenzhen IC distributors. These will be enough to make 100 sensor tags for us to test reliability of this local distributor and fulfill some 20 back-orders. 

Meanwhile we have fully tested the URL calling feature, which now also lets user choose if server calls the URL or the Ethernet Tag Manager calls the URL. The latter option will work even if the URL is using a private local IP address (such as, etc), or the REST endpoint is behind a firewall. The latter option requires firmware update of the Ethernet Tag manager, so will not be available to customers (about 30) who already received our product. However, per request, we will update your firmware at no cost if you mail the Ethernet Tag Manager to us.  

Current sensor tags is under development and will be released by end of this year. This interests us immensely, imagine knowing how much electricity each appliance used each day, each month, and knowing at a glance, anywhere with Internet access, if each machine/equipment is on or off and how much electricity it is using. This tag will have a unique, custom designed transformer based 50/60Hz AC current sensor which attaches to a power outlet without physical contact (this will not be a series resistor type sensor which introduces power loss and reliability/safety concerns). No tools will be required for installation/removal.

We are also working hard to write a program to generate our JSON AJAX API document using .NET Reflection API, so any update in server side source code automatically updates the document. We recognize that having an open API is important not only for allowing advanced users to integrate our product into existing systems, but also to allow independent solution providers to develop apps for platforms not supported currently, such as Windows Phone. Our Android and iOS app is written entirely using these set of JSON AJAX API for which we will release SDK in the near future. 


 We buy the majority of our components in USA and ship to Shenzhen, China for PCB (printed circuit board) assembly. Small quantity (<4000 units) PCB assembly is a labor intensive process, because manual labor is needed to organize/sort/inventory hundreds of types of component in cut-tapes, which is why even PCB companies in US out-source PCB assembly to China. We are currently experiencing a little longer than expected Chinese Customs clearance time. Before, our shipment from USA clear Chinese customs in a few days, now it has been more than a week. There should be about 1 week delay from originally planned ship date. We will have to establish a different method of production to avoid going through Chinese customs in the future.

Calling custom URL on each type of event, and allowing user to download raw motion & temperature statistic data as Excel spreadsheet (CSV) have now been implemented and are available to our existing and future customers. The Web/android app user manual has been updated. 

Custom URL calling allows you to integrate our product with Web service (REST endpoint) enabled home automation systems such as Insteon/ISY by Universal Devices. For example, you can turn on a light when door is opened, or motion is detected. In another example, you can turn off every light at your home when a tag (that may be attached to your key chain) is out of range.


Due to the sudden coverage by, we are receiving a lot of orders in the past 24 hours. We have scrambled last night to order almost $10,000 worth of components from DigiKey and Mouser and will have them express shipped to our PCB assembly company. For this batch, the final shipping should be before mid-September. However. these components will only be able to cover about 75% of orders we received so far. For the other orders, the shipment is expected to be end of September ~ early October. We will send you a detailed timeline after you place your (pre-)order. 

Since we hand assemble and test every order we ship, our production capability is limited. Your orders will be  processed as carefully as any other orders we shipped so far, as we ramp up our production capability. Thank you for your orders and interest in this product. 


A new generation of wireless smart tags, "Wireless Sensor Tags" are available to purchase today from Shopify. All orders will be shipped within 48 hours. Compared with 1st generation which are now discontinued, we have made them much more useful for you:

  • The USB Tag Manager is replaced with a standalone "Ethernet Tag Manager." Plug it into wall and to your Internet modem, and the system will be available 24/7 to access from the Internet, or by using iPhone/iPad/Android apps, without the need of a PC at all. 
  • A new radio and antenna design increased wireless range by 2~3x. 
  • Lots of new features such as temperature monitoring, logging, complete smart phone/tablet Integration: instant notification by Apple Push or Google C2DM (like SMS but without messaging charge), Twitter, spoken tag name, associating image to each tag, message customization, arm/disarm scheduling, door statistics, and more. 
  • Each wireless tag now conserves more energy to make the battery last a lot longer.
  • All new free iPhone & iPad apps are available in AppStore.
  • All new free Android app is available in Google Play. (supports Android version 2.2 or higher)
  • The web interface is also greatly expanded to allow full access to all available features.
