Possible to create zwave trigger from plugin?

My plugin requires that it receives a trigger when a zwave command reporting a thermostat's temperature is received.

I can set this up manually but after having looked at the Trigger documentation I was wondering if it is possible to dynamically create a new trigger for this at run time in the Plugin as a device is created

The trigger details are:
Trigger = Z-Wave Event, Z-wave Command, Thermostat, Temperature Update
Condition = Always
Actions = Plugin Action, Plugin Device

I have looked in the database at the trigger created via the UI, which shows as:

Code: Select all

      <Trigger type="dict">
         <ActionGroup type="dict">
            <ActionSteps type="vector">
               <Action type="dict">

                  <ObjVers type="integer">12</ObjVers>
                  <PluginID type="string">com.perceptiveautomation.indigoplugin.stellaZcontroller</PluginID>
                  <TypeIdPlugin type="string">zwave</TypeIdPlugin>
                  <TypeLabelPlugin type="string">Process Z-Wave Command</TypeLabelPlugin>

         </Condition>
         <Enabled type="bool">false</Enabled>
         <FolderID type="integer">611445155</FolderID>

               <targetDev type="string">525749084</targetDev>

      </Trigger>


Thanks for any help

Unfortunately, not yet. We haven't finished the IOM for Triggers and Schedules and more specifically haven't yet implemented Action support. It's on the list but demand has been fairly low.

However, I think a better approach for your use is to subscribe to device changes. You will then get device update messages any time a device has any change. You can then check to see if the device is a thermostat and then further check to see what exactly changed and perform whatever functionality you need.

Thanks for the suggestion which seems a lot easier than what I was asking for

I have tried it out but notice that I am getting two messages for every temperature update event e.g.:

Code: Select all

  Z-Wave                          sent "T01_Thermostat" temperature status request
  Z-Wave                          received "T01_Thermostat" temperature update to 18.0 °C
  Autolog Device                  AUTOLOG PLUGIN: Device Updated = T01_Thermostat
  Autolog Device                  AUTOLOG PLUGIN: Device Updated = T01_Thermostat


i was doing a bit more reading in the forum and see that there is a indigo.insteon.subscribeToIncoming() method.
I tried indigo.zwave.subscribeToIncoming() but got an error.
Ideally, I am looking to only handle one event instead of two.

Am I doing something wrong or is this function not (yet?) available for zwave?

There is not yet a way to subscribe to raw Z-Wave messages.

How about filtering the messages to avoid the duplicates? If you are only interested in temperature changes, then you could save off the last value sent and compare that to the incoming in a conditional such that your logic is only executed if there is a real change.

OK, I'll do as you suggest - Thanks for the quick reply
