    Question about Latency

    I started out with Control4 professional install - 2 years ago. Control4 interface was ugly and the software extremely unfriendly. I started to change over to Homeseer about 3-4 months ago and have been having great success. I have been slowly converting over the Control4 devices to Homeseer - migrating from one end of my house to the other (to avoid hiccups). I have noticed increased latency when triggering some events and some events just not triggering.

    - I have run optimization from the z-troller (not from the individual nodes) and it doesn't seem to have a big impact.
    - the distance between any two devices is very short (longest gap is a flight of stairs).
    - currently have 40-ish nodes (primarily Homeseer switches and dimmers)
    - The polling interval has not been changed from the default setting

    Question
    - would adding a second/third HomeTroller improve the communication/latency?
    - Should I optimize the individual nodes?
    - How does one go about interrogating the z-net to find the problems?

    Been playing around
    - randomly picked one node (in the middle of the house)
    - did an Audit of the node from the z-wave tab

    Auditing node 51 (Main Pantry Pantry Lights) ...

    HomeSeer was able to send a frame to the node.
    HomeSeer was able to query the node and receive information back from it.
    The node's neighbor rating is: Poor with 0 neighbors.
    This node supports associations on the following groups:
    Group 1:
    Controller Z-Wave Homeseer Z-NET (Node 1)
    Group 2 - No nodes are associated to this group.

    Finished!

    - That's the message I get from the audit
    - This node has at least 5 neighbors (there are two in the gang box) within 3 feet.

    - I have run a Optimize and Full Optimize and still get the same audit response.

    Does this seem right?

      That doesn't seem right. I picked a few nodes and they all look similar to this

      What does the Node Information page (Plugins->Z-Wave->Node Information) show? Note that the "Neighbors" field matches what the audit reports.

        - I have tried the majority of my nodes - and they all have a poor rating.
        - Not quite sure what I need to do to change that
        - These nodes are all within a few meters of each other

          And nothing changes after an optimize or full optimize of the node?

          Do you have Z-Seer+ ? While not necessary, it might be handy. Its not too pricey.

          You might consider resetting the Z-Wave database (from Plugins->Manage, click on Z-Wave, then click 'Reset Z-Wave Data'. You should backup the system prior to this.

          On the Zee, the Z-Wave database resides at /usr/local/HomeSeer/Data/Z-Wave/Z-Wave2.db, so back that up at least.

            I have the hometroller Zee S2
            - I have run the full optimization from the z-wave controller multiple times - no change
            - I have run the optimize from the individual node - no change

              #7
              I changed the location of the Zee S2 - almost dead center of the house and re-ran the fully optimize command.
              - no change - more neighbors, all with still poor neighbor rating
              - the Hometroller is connect via ethernet

                This may not change anything but I would turn off ALL polling on powered devices(you mentioned they were set at "default"). In general it just clogs up the z-wave system and makes it less responsive and is not necessary. Scan down your "Plugin/zwave/node information" and look for "polling disabled" on root and child devices.

                  The polling is off on all the powered devices. It seems to be the default setting for all the homeseer switches and dimmers.

                    I moved the Zee S2 to the center of the house
                    - re-ran the full optimize - no change
                    - restarted homeseer and many of the nodes are working very well
                    - I still have two nodes that have poor neighbors
                    - they are extremely close to the hub and they are both Homeseer switches

                      - It should have dozens of neighbors and a decent signal
                      - It's within arms length of the Zee S2 and within arms length of 6 homeseer switches and less than 15 feet from several more nodes

                        I suppose its possible that some of the nodes are defective.

                        I ran through all my switches and the lowest rating was two nodes that reported "acceptable with 9 neighbors". One of these perhaps makes sense as it is one of the farthest from the controller, but the other one is maybe 8 feet from the controller and inches from two other nodes that report 15-16 neighbors. So that one is either weak or there is some sort of interference.

                        One thought - what type of electrical boxes do you have? Mine appear to be fiberglass. I imagine these would be better than the metal ones for this application.

                          - All plastic boxes...both of the nodes are in multiple gang boxes and the other nodes are not having the problem
                          - If it's a bad node - wondering if I should re-pair the node with the system. Would hate to have to pull the whole node out and replace the switch.
