I have a Monster remote that controls my AV and lights. I just learned about Vera by Micasaverde, which will allow me to control locks, thermostats, and lights with my Apple iPhone. Can I keep using my Monster remote and use the Vera iPhone interface to control the same things? Put another way, can I pair the same light module to both the Monster remote and the Vera with full functionality, allowing me to choose either the monster remote to turn off all the lights or the Vera interface to turn off all the lights?

According to Aaron Bergen at Micasaverde, the Vera can be used as a secondary controller with the Monster AVL-300 as the primary. The only device that may have a problem is the Schlage lock. It’s not certain that you will be able to add a Schlage lock to Vera in that configuration, because the Z-Wave controller that includes the Schlage lock must support secure key exchange. The AVL-300 does not, so it cannot include the Schlage lock. If the AVL-300 supports SUC/SIS (a technology that allows controllers other than the primary to include nodes), then Vera should be able to add the Schlage lock even though Vera is secondary. But, if the AVL-300 does not support this, then it may not be possible to add the Schlage lock. This is not a limitation of Vera; it’s just the way Z-Wave works.

I have looked around the market for a simple thru-socket that will read the current being drawn through it, and transmit the data real-time. Do you know of one that exists?

While there are several of these type products on the market in both North American style and European styles they all have local display screens and do not use Z-Wave to transmit the information. The Z-Wave protocol has all of the necessary Command Classes (a standardized way to report this information) in place and several Z-Wave OEM’s have inquired about these types of devices so I would expect to see some reaching the market soon.

We are using a Zensys controller for implementing Z-Wave to communicate between static controller and slave. From the document provided with the demo kit we came to know that for storing HOMEID and routing tables at the static controller side, external EEPROM should be provided. Now, is it necessary to provide the external EEPROM? Or, we can store the same information on the internal EEPROM?

For a Controller node you should use an external EEPROM, that is the recommended way to do it. It is possible to build a slave node with just the Z-Wave chip using the internal EEPROM and no other supporting chips. These types of questions are best directed to Zensys through the support.zensys website. As a development kit owner you have access to this site and all of the proprietary development information you need to create a product based on the Zensys technology. You also have access to Zensys technical support engineers through this site. is an independent site and while we aim to meet all of the needs of the Z-Wave community we cannot provide detailed technology implementation advice. Such advice should come from Zensys.
