ZWave Configuration Options

Revision as of 02:43, 5 January 2009

When you go to the devices tab on Vera's setup site and click '+' next to a Z-Wave device, you will see Z-Wave specific options for that particular device.

The node ID is the ID number the device has on the Z-Wave network.

Z-Wave devices are normally polled to see if the device is working ok and if the status has changed, such as the device having been turned off or off, etc. Normally leave this blank to let Vera do the default polling, or see polling settings to learn how to change this.

Very few Z-Wave devices actually are able to report how much energy they are using. So, in general, Vera estimates this based on the Wattage. By default each light will have 100 watts. If the light really is a 100 watt light, you can leave it. If not, put in the correct wattage. For lights, this is usually printed on the bulb. Remember that if multiple lights are on the same Z-Wave switch you should add the wattages. You can also specify the wattages for appliance modules, for example, if you have a fan, which typically use about 200 watts, plugged into an appliance module. Vera will constantly poll all the Z-Wave devices in your home to see if they are on, off or dimmed to a certain level, and Vera will use this to estimate the electricity being used. Also see: Energy

Configure node right now: This causes Vera to attempt to configure the device immediately. After clicking this button you see the job icon for 'Configuring the device' next to the device description and it will turn green if Vera was able to configure the device, or red if Vera was not. See diagram of job icons. Some devices, like motion/door/window sensors, are generally not functional until they are configured. If they are not configured, you will see the configure job icon in red. But if the device is battery operated, it's quite possible that, in order to conserve battery life, the device goes into a 'sleep mode' where the Z-Wave radio is turned off, and Vera cannot configure it. In general these battery operated devices wake up every few hours and announce that they're going to be awake for a few seconds. When this happens, Vera will use that opportunity to configure the device. So, if you added a battery operated device and you see the red 'configure job icon', indicating the device is not configured and is not usable, you can check back the next day and it probably will be configured. Or, often times, the sensors allow you to remove and reinsert the batteries, or to press a button, and this will force them to listen to the Z-Wave network for a minute or two. See Supported_Hardware for a list of some popular Z-Wave sensors and an explanation of how they work. If you have a sensor like this, you can then manually 'wake it up', and then you can right away click the 'Configure node right now' button to make Vera try to configure the device. This button is also useful if you have changed specific Z-Wave configuration and association settings and want to see them applied right away, as explained below.

Poll now: This cause Vera to attempt to poll the device right now. After clicking it you see a poll job icon as shown here diagram of job icons, and it will green if Vera successfully polled the node, and red if not. To learn what polling is, why it's done, and how to change the polling settings, click here

Permanently remove dead node: The list of Z-Wave devices which have been paired with Vera's black Z-Wave dongle is stored within the dongle itself. This means that even if you do a factory reset of Vera, which wipes out all of Vera's memory, once Vera comes back up, you'll still have the same list of Z-Wave devices. If there's a node in your home and you want to remove it from the Z-Wave network, the best way to do this is to exclude the Z-Wave device, also known as resetting the device. click here for an explanation. If the Z-Wave device is broken or gone, then you won't be able to exclude it like normal. In this case, there are only 2 ways to permanently remove the paired Z-Wave device from Vera's Z-Wave dongle. One option is to choose 'Reset Z-Wave network' from Vera's |ZWave options page. But that removes all nodes and resets the dongle. The other possibility is to click this button to remove one particular node. You may need to do this if you added a ZWave controller, then reset the ZWave controller, then added it again, as explained here.

Custom Z-Wave Settings

Custom Z-Wave Settings: Click this button to see more Z-Wave specific options for this device. Click the 'Back to devices' link when are you done making these changes to go back to the devices page.

Configuration settings: Some Z-Wave devices allow you to manually set configuration variables to do things like adjust ramp rate and so on. This is unique for each device, and each manufacturer handles this differently. If the manual for your Z-Wave device indicates that you can set a configuration variable or setting to change the default behavior, do it by clicking the 'Add configuration setting' button. Indicate which variable number to set, and what value to set it to. The value can be a '1 byte hex', '1 byte dec', '2 byte hex', '2 byte dec', '4 byte hex' or '4 byte dec'. If you do not know what this means and the manufacturer did not tell you which one they want you to choose, then choose '4 byte dec'. Put the setting you want in 'desired' setting. Vera will attempt to configure the node after you click the red 'save' button, and if successful, you'll see the [[Device_Control_Status#Job_icons|green 'configure job' ok icon]. If it's a battery operated device and Vera can't configure it right away, read the comments above about the Configure node right now. Once Vera has configured the ZWave device, Vera will ask the device again for the value of the configuration setting and show it under 'Current Value'. If you set a value, configured the device, and the current value is something other than your desired value, that means the ZWave device did not accept the 'Desired value' you gave it, and you may need to contact the manufacturer for clarification. If you change the 'Data Size' option to say 'Monitor only', then when the device is next configured Vera will not change the value, but Vera will ask the device for the current value and show it on the 'Current Value' column. If you change it to 'default', then the next time Vera configures the device Vera will tell the device to go back to the default value for this setting, and you'll see the value in the 'Current Value' column.

Associations: These are also unique for each device according to the manufacturer. Associations are commonly used to tell sensors to turn on lights, and to associate devices. Refer to the manufacturer's users manual that came with the ZWave device to learn how they handle associations. Associations are given an ID or group ID. To add an association, type in the group id, which is a number, click 'Add Group' and then check off the Z-Wave devices you want to be associated. Vera will attempt to configure the node after you click the red 'save' button, and if successful, you'll see the [[Device_Control_Status#Job_icons|green 'configure job' ok icon]. If it's a battery operated device and Vera can't configure it right away, read the comments above about the Configure node right now.

Scene Assignments: If this is a ZWave controller, then you will have another section on this page to assign scenes to the controller's buttons, as explained here. You won't see this for other types of ZWave devices.
