What is Z-Wave, Z-Wave Plus, Z-Wave S2, Z-Wave SmartStart and Z-Wave Plus V2

 



Z-Wave is a wireless communication technology that uses reliable, low-power radio waves that easily travel through walls, floors and furniture, meaning you don't have to rip-up carpets and floors to add new wiring.

Features such as two-way communication, status updates and mesh networking combine together to ensure reliability and resiliency in your Home Automation system - no more wondering whether the light in your garage really turned off when you closed the door!

Using Z-Wave enables you to easily create a modern smart home, giving you control of your lights, appliances, heating, security and multimedia at the touch of a button.

Z-Wave is the leading wireless home automation technology offering significant benefits compared to older technologies

• Two-way wireless communication - all messages acknowledged, if one gets lost it is automatically repeated
• Status updates - you know the status of every device on the system (lights, heating, appliances...)
• Mesh networking - automatically covers dead-spots, great for large installations
• Easy control - use a remote control, central controller, smartphone apps or via the Internet

There is one area to bear in mind with Z-Wave - the RF frequency ranges used are different in each territory due to regulatory requirements in the sub-1GHz band. In Europe Z-Wave devices all use the 868.42MHz frequency and this is the type of devices that Vesternet sells. These will not work with Z-Wave devices or Z-Wave Controllers that use different frequencies! For further information see the Silicon Labs reference.




 



Z-Wave Plus is a new certification program designed to help consumers identify products that take advantage of the recently introduced "Next Gen" Z-Wave hardware platform, also know as 500 Series, 5th Generation, Z-Wave for Gen5 or just plain Gen5. Z-Wave Plus certified solutions feature a selected set of extended features and capabilities that enhance the end user experience and make Z-Wave systems even faster and easier to install and set up.

Z-Wave Plus improves on the original specifications of Z-Wave by making use of the latest advancements in this exciting technology. With the introduction of the Next-Gen, Z-Wave has extended its capabilities, including increased range, extended battery life, Over The Air upgrading (OTA), additional RF channels and more - all of which are fully backwards compatible with existing Z-Wave products. These enhancements offer tremendous benefits in terms of shorter and easier installations, richer device profiles, improved self-healing and longer battery life.

Z-Wave Plus extended features include:

• Greater Range - significant increase in range, now up to 150m (clear air)
• Lower Power Requirements - 50% improvement in battery life
• More RF Bandwidth - 250% more
• Stability - three F channels for improved noise immunity and higher bandwidth
• Easier Inclusion & Exclusion of devices - new Plug-n-Play Network-wide Inclusion feature
• Reliability - improved self-healing and fault tolerance with Explorer Frame network discovery
• Firmware Updates - standardised method for Over the Air firmware updates (OTA)
• Device Data - improved product information capture for product certification database

The new features of the Z-Wave Plus devices are a great extension to Z-Wave and will help you make the most robust, solid wireless home automation system possible. But, you need to be a little careful of expectations - especially as the first devices are introduced using the new features and command classes available in the Z-Wave 500 series chips.

If you have a complete Z-Wave Plus system, where every device is of the new Gen5 variety, then you wouldn't have any issues. They would work together seamlessly (better than any Z-Wave system so far), and you would get all the benefits that the new features offer such as extended battery life, much longer range and increased bandwidth.

However, if you're mixing with existing Z-Wave devices, sensors and controllers based on the 300-series and 400-series Z-Wave chips then it does mean that you may miss out on some of the benefits of the Gen5 devices.

Battery Life

The battery life for Z-Wave Plus devices is significantly improved over previous generations. It doesn't rely on any other devices in the system, therefore, you should see the extended battery life offered by Z-Wave Plus devices - up to 50% longer than existing devices.

Range

The range of devices relies heavily on other devices in the network. If you are using a mix of Z-Wave Plus and existing devices you may not see the increase in range offered by Z-Wave Plus.

Controller

The main consideration is the Z-Wave controller - if the controller is not Z-Wave Plus enabled than all devices added to that controller's network will default to acting as Z-Wave. This is because Z-Wave Plus is backwards compatible with Z-Wave, so when Z-Wave Plus devices are installed with Z-Wave devices they behave just like a Z-Wave device.

If you do have a Z-Wave Plus controller, then you should start to see the benefits of Z-Wave Plus, as long as other devices in any "routes" to the Z-Wave Plus device are also Z-Wave Plus. Otherwise, the device will again default to operating as a plain Z-Wave device.




 



S2 is an extension to the security framework of Z-Wave Plus devices. It enables manufacturers to offer best-in-class security without any compromises in terms of power consumption or latency.

Sigma worked hand-in-hand with cybersecurity experts to develop the actual specification for the S2 extension that gives Z-Wave devices new levels of security. While Z-Wave already leads in security with AES 128-bit encryption level, which is available to all devices, S2 improves this by adding full diffe-hellman symmetric encryption to the key exchange as well as using a single command structure that replaces the previous three-step process, which reduces latency and improves battery life for devices using S2.

SmartStart aims to simplify the process of Including Z-Wave devices and builds upon the functionality that was introduced by S2.

By removing as much user interaction as possible, SmartStart now makes it a breeze to add new devices to your Smart Home system - simple scan the device QR code in the Z-Wave controller App and power on the device!

SmartStart also introduces further enhancements such as the "Provisioning List". This allows multiple devices to be Included simultaneously simply by powering them all on. For system builders and installers this will be a huge help, because now all device QR codes can simply be added to the Provisioning List in the Smart Home controller prior to shipping to site. The installer or customer then powers on the Smart Home controller and all the devices and the system will set itself up automatically!

Z-Wave Plus V2, also known as 700 Series or Gen7, builds on the work that began with Z-Wave Plus and the incremental improvements of S2 and SmartStart. From the firmware to the chips themselves, Gen7 brings massive increases in wireless range, vastly superior security, faster operation and all while decreasing power consumption yet again.

The 700 series edition of Z-Wave Plus chips and modules offer major advantages over older versions of Z-Wave in a lot of different categories. End users will notice them the most in wireless speed and improved battery life. Developers will notice them the most in the improved wireless range and the improved memory.

Z-Wave Plus V2 extended features include:

• Greater Range - significant increase in range, now more than 200m (clear air)
• Lower Power Requirements - up to 10 years battery life
• More RF Output Power - up to +13 dBm
• Easier Inclusion & Exclusion of devices - Network-wide Inclusion and SmartStart features now mandatory
• Security - security first by design, encryption, ecdh and other improvements
• Firmware Updates - Over the Air firmware updates (OTA) now mandatory
• Frequency Flexible - Built in SAW Filter allows one device to support multiple Z-Wave frequencies
• Improved Performance - 700 series chips now ARM Cortex M4 based using faster CPU, more menory and greater storage

All in all Z-Wave Plus V2 offers even more features that will increase the reliability, stability and performance of your Smart Home, but as with the move from normal Z-Wave to Z-Wave Plus, expectations should be tempered somewhat if your existing Z-Wave controller only supports Z-Wave Plus and your existing devices are a mixture of Z-Wave and Z-Wave Plus.
