Testing a Z-Wave device to verify it is receiving power

How can I test a Z-Wave GE outdoor switch to verify that it has power? I need to trigger an email if power has been lost.

I would periodically send a status request and look for a response. If you get an error back its unreachable. Either no power, or other issues. You could send an email on that.

The problem seems to be that the trigger activity only looks at the state of the device, not error status. Perhaps a Python approach is required.

Yeah, you could do something like this periodically to execute an Action Group if a ping command fails to the device.

Code: Select all

result = indigo.device.ping(DEV_ID_HERE, suppressLogging=True)
if not result["Success"]:
  indigo.server.log("ping failed", isError=True)
  indigo.actionGroup.execute(ACTION_GROUP_ID_HERE)


I guess I need a little more Python help. I ran the following as an embedded script and got the error below.

Code: Select all

result = indigo.device.ping(Water_Feature, suppressLogging=True)
if not result["Success"]:
  indigo.server.log("ping failed", isError=True)
  indigo.actionGroup.execute (Sump_Pump_Power_Failure)


Code: Select all

 Script Error                    embedded script: global name 'Water_Feature' is not defined

result = indigo.device.ping(DEV_ID_HERE, suppressLogging=True)

DEV_ID_HERE needs to be the device ID, not the name.

Right-click the device in Indigo, and "Copy python reference" or something like that.

Paste that in instead.

Well, it can be the name, but it needs to be a string.

Code: Select all

result = indigo.device.ping("Water_Feature", suppressLogging=True)


Using the ID is better, in case you change the name.

But the rest of that code is suspect, depending on how you indent it. Use the 'Code' tags when you post Python code.

OK, I have made a little progress. The script below now generates the following error.

Code: Select all

result = indigo.device.ping(indigo.devices[1637128522] # "Water Feature", suppressLogging=True)
if not result["Success"]:
  indigo.server.log("ping failed", isError=True)
  indigo.actionGroup.execute(Sump_Pump_Power_Failure)


Code: Select all

   Script Error                    embedded script: invalid syntax
   Script Error                    around line 2 - "if not result["Success"]:"

Use the code tags. As I said, you have an indentation error, but we can't tell you how to fix it.

Python uses indentation to delineate code blocks, so your logic will depend on the indentation.

Change this line from:

result = indigo.device.ping(indigo.devices[1637128522] # "Water Feature", suppressLogging=True)

to:

result = indigo.device.ping(1637128522, suppressLogging=True)

Heh. I didn't notice that he put the comment inside the function call. Oops. But there's still a syntax/logic error.

True, my eyes missed that one. Fixed.

And found another problem. Post edited again to hopefully show the correct line.

OK, here's the latest;

The script

Code: Select all

result = indigo.device.ping(indigo.devices(1637128522,suppressLogging=True)
if not result["Success"]:
  indigo.server.log("ping failed", isError=True)
  indigo.actionGroup.execute(1684269810)


The error

Code: Select all

   Script Error                    embedded script: invalid syntax
   Script Error                    around line 2 - "if not result["Success"]:"

You have unbalanced parenthesis on the line before.

Use the code from Matt's post above.
