Question about Mesh Network

[RamyLabib 1]

The Z-Wave network is a mesh network.  This means that the signal received by one listening device or node is relayed to neighbouring nodes up to four nodes away from the original sender.  This extends the range of the network and provides stability.

 

I have read this earlier in the Fibaro Website and I want to know what that precisely means.

I have 2 scenarios in my mind now.

1) It means that the HC2 send signal to relay1 which can send it to relay2 which can send it to relay3 which finally can send it to relay4.

 

    ** HC2 --> relay1 --> relay2 --> relay3 --> relay4 --> no more

 

2) It means that HC2 send signal to for example relay1 and relay2, then each relay of those can send signals to up to 4 other relays.

 

    ** HC2 --> relay1 --> (4 other relays)

                --> relay2 --> (4 other relays)

 

So which scenario is the right one ??

Hello,

 

As it describes, Z-Wave is a mesh network which means that a signal has to make a route from a gateway to a device in case of problems with direct connection. It can use up to 4 nodes to route the signal from a gateway to a device.

Frankly, it works more like the second way you described. A device sends a signal to neighboring devices (and so on, so on) and a gateway can decide which route is the best for connection.

Is Fibaro a member of the Sigma Developer Community?

Does Fibaro has access to Sigma Dev Kit?

 

Sigma has made available an IMA Tool which Fibaro should be able to look into inclusion in Home Center.

 

 

 

How does IMA actually work?
IMA works primarily by tracking and noting key metrics, and then anyone from service providers to homeowners can use that data to better optimize the overall network.
According to Adams, one of the key metrics to track is the number of nodes a signal can use to traverse from the control panel to the final product. Since Z-Wave functions as a mesh network that enables all connected endpoints to act as a signal repeater, using IMA to determine exactly how many items are within the overall network can pass along a given signal is key since it gives service providers with an idea on how healthy and resilient the network as a whole truly is.
Another key variable that the IMA toolkit tracks is the distance that each signal traveled. While a Z-Wave signal can easily traverse 90 feet indoors and up to 250 feet outside, those are not always the ideal . In some cases that may be perfectly okay, but in others more nodes may be needed to strengthen the overall signal. Using IMA, service providers can find the exact distance each signal travels and make adjustments if necessary.

With this tool, it will seriously help us to better understand, and better troubleshoot issues.

Fibaro should have access to sample code to create IMA diagnostic app to include/reside in Home Center.

+1 !

 

Would be really great to have something (or this IMA tool) to "debug" the Z-Wave network.

IMA as code does exists since some time, and yes, Fibaro did implementet part of that code (known as Fibaro Range test). IMA as Tool (hardware + software) will be soon available for all z-wave certified installers

 (all the other members can use z-wave zniffer, which is even more powerful)
