Q. I’ve heard of Matter with Z-Wave, what is this?

A. Matter is a new protocol being launched by the ZIGBEE Alliance. The protocol is to be launched to help with operability between all brands’ ZIGBEE devices, so they all work together equally. However the Z-Wave Alliance are also working alongside on the new Matter protocol to improve interoperability.

Q. I already have some Z-Wave products, is Matter going to cause issues with these?

A. If you already have Z-Wave products, then no Matter shouldn’t cause issues with these. The Matter protocol is using existing technologies already in place so anything you already have should continue to work, the Matter protocol will be more applicable to future products coming out.

Q. Is there a limit to how many devices I can run on a Z-Wave Network?

A. Yes, there is a limit to how many devices that can be run on a Z-Wave Network. You can run up to 232 Z-Wave devices on a network although there is the new Z-Wave LR which is being worked on which can mean 4000 devices could be paired to a Z-Wave network.

Q. Can I add more Z-Wave hubs to my network to increase how many devices I can control?

A. Yes, you can add more Z-Wave hubs to your network to increase how many devices you can control. Depending on the manufacturer, you can usually add more hubs so you can control more devices.

Q. What frequency does Z-Wave work on?

A. The frequency Z-Wave works on is generally between 800-900MHz, the exact frequency depends on where you are in the world.

Q. Can other protocols using frequencies interfere with Z-Wave?

A. Generally, it is not possible for other protocols using frequencies to interfere with Z-Wave. A lot of control protocols e.g., Wi-Fi, Bluetooth, Zigbee all use the 2.4GHz frequency. However, with Z-Wave being around 800-900MHz it doesn’t suffer interference from those protocols.

Q. Can Z-Wave penetrate through walls?

A. Yes, Z-Wave can penetrate through walls, but it also comes down to what the walls are made of as well as how thick they are. If they are too thick etc. then you may need to extend the Z-Wave network range to get around this.

Q. Do all Z-Wave devices act as repeaters and extend the range of the network?

A. No, not all Z-Wave devices act as repeaters to extend the range of the network. Generally, any Z-Wave device that is plugged in/runs from the power can act as a repeater. If, however you have a device that is running from batteries, then it is likely that will not act as a repeater as these would generally run out of battery quickly if they did.

Q. Can anything else cause interference with my Z-Wave equipment?

A. Yes, there are other things that can cause interference with your Z-Wave equipment. If you’re mounting your Z-Wave equipment anywhere where there may be a lot of electromagnetic interference e.g., near speakers/amplifiers then this may also cause issues.

Q. Is Z-Wave secure?

A. Yes, Z-Wave is secure as it uses strong encryption and authentication algorithms to help keep your data safe from any cyber threats.

Q. What is a Z-Wave mesh network?

A. A Z-Wave mesh network is a group of devices that act as a single network. In a mesh network, nodes/devices are interconnected with other nodes/devices to create multiple pathways around the network and to each device. These nodes and their connections are dynamically updated and optimized so if you add or remove devices, the network will adapt to keep everything communicating.

Q. Will Z-Wave interfere with my Wi-Fi network?

A. No Z-wave operates on a different frequency than Wi-Fi, so even though your hub will plug into your router they won’t cause interference with each other.

Q. How will I know which Z-Wave devices work together?

A. The way to know which Z-Wave devices work together is to look for the Z-Wave logo. All Z-Wave products are built to be interoperable regardless of manufacturer.

Q. What is the difference between Z-Wave and Z-Wave plus?

A. The difference between Z-Wave and Z-Wave plus is age. Z-Wave items are the first generation with Z-Wave Plus now being the newest generation of Z-Wave products. There is no compatibility issues between the 2 and both generations will work together.
