No this "ps4-waker check" command I cannot get working at all with MSR. It always shows an error.

The other command "ps4-waker" does work most of the time.

[cw-kid]

I have two different rulesets.

This is the working one:

However the other rule with "check" on the end of the command has never worked and errors.

I always see these Alerts:

[toggledbits]

Could it be that "check" returns a non-zero exit code depending on its result? Many utilities do this. A non-zero exit code would be interpreted as an error by MSR.

@toggledbits

I'm not sure, when I run the check command in terminal it always outputs something like this:

{
  "type": "device",
  "statusLine": "620 Server Standby",
  "statusCode": "620",
  "status": "Standby",
  "host-id": "C863F1400EF1",
  "host-type": "PS4",
  "host-name": "PS4-806",
  "host-request-port": "997",
  "device-discovery-protocol-version": "00020020",
  "system-version": "08520011",
  "address": "192.168.0.201"
}

statusline "620 Server Standby" means the PS4 is currently in sleep mode.

Think it says "200 OK" when the PS4 is turned on and running.

I was wondering if I could extract that device power status using MSR and then maybe send it to a virtual device in Vera / Home Remote etc.

Also that check command can tell you which app is currently opened on the PS4 and also possibly which game is currently being played.

But its not required I guess, I just wanted to see if it could be done somehow.

The main thing is the PS4 is turned on when the other MSR rule detects that my Harmony activity for the PS4 has started and that at the moment seems to be working OK.

[toggledbits]

Try running the command this way (yourself, in a shell, not in MSR):

    ps4-waker check ; echo $?

This will display the exit status of the command after it runs. You may need to run this repeatedly, under various different expectations of status, including testing when the device is disconnected/powered off, to get a complete feel for what shell exit status ps4-waker is returning under various conditions. Anything other than 0 is going to be a problem (it looks like an error). Using non-zero exit codes is a very common way for some utilities to return their status quickly so that shell scripts can make quick decisions without having to parse other data (like your output), so it's very likely that under some condition this script is working fine but returning non-zero. If that's the case, you're going to need a wrapper script to "deaden" the exit code.

I've also just pushed up a new build to latest that has additional logging for this action, so you can try that as well and see if it gives any new information. I would not upgrade to latest in lieu of doing the above, as I cannot display the exit code (at least, not that I've found, as yet), so the above test is still a necessary important step. This will simply add stderr output to the logging (although I suspect the prior error messages already contain all the relevant output -- this is a safety/assurance that we're seeing it).

When the Playstation is in sleep mode:

When the Playstation is turned on and running:

Your right the MSR rule is working and returning data only when the Playstation is turned on:

I thought it wasn't working when turned on but clearly it now is.

So because the exit code is a 1 when the Playstation is turned off that is why the MSR rule then does not return any data?

Thanks

[toggledbits]

That's correct. Any non-zero is an error. I will add a checkbox to the action to (optionally) ignore the exit code, and make that available in a build later today.

[cw-kid]

@toggledbits

That's great thank you.

Next problem how to extract the data from the in rule expression and split out the PS4's power status out in to another expression ?

I guess either "statusLine" or "statusCode" could be used.

(string) "{\n \"type\": \"device\",\n \"statusLine\": \"200 Ok\",\n \"statusCode\": \"200\",\n \"status\": \"Ok\",\n \"host-id\": \"C863F1400EF1\",\n \"host-type\": \"PS4\",\n \"host-name\": \"PS4-806\",\n \"host-request-port\": \"997\",\n \"device-discovery-protocol-version\": \"00020020\",\n \"system-version\": \"08520011\",\n \"running-app-name\": \"Concrete Genie\",\n \"running-app-titleid\": \"CUSA11875\",\n \"address\": \"192.168.0.201\"\n}\n"

And you can see there is also a "running-app-name" Concrete Genie is the game being played currently.

[toggledbits]

Use another expression to put that string through the parseJSON() function and it will turn it into an object you can then pick the data out of.

[cw-kid]

@toggledbits said in Having issues with a shell command:

parseJSON()

Like this ?

Contents of the expression "ps4wakerparse"

Last value:(object) {"type":"device","statusLine":"200 Ok","statusCode":"200","status":"Ok","host-id":"C863F1400EF1","host-type":"PS4","host-name":"PS4-806","host-request-port":"997","device-discovery-protocol-version":"00020020","system-version":"08520011","running-app-name":"Concrete Genie","running-app-titleid":"CUSA11875","address":"192.168.0.201"}

[toggledbits]

I don't know what the first expression is/was, but the second one is correct and has parsed the value correctly. You can now refer to data in the object via ps4wakerparse.statusCode for example. For names that contain special characters, like host-id, you need to use the alternate (quoted identifier) syntax ps4wakerparse["host-id"]

@toggledbits

Seems to be working and pulling out the required data:

The first expression named "ps4wakercheck" is the inital output of the shell command "ps4-waker check".

[toggledbits]

OK. I see that it's not consistently clearing the error from some prior usage on ps4wakercheck, that's what's confusing/odd, so I've fixed that for today's build as well (PR 0000235).

[toggledbits]

By the way, it's much more efficient to use expressions in ps4powerstatus and ps4runningapp than it is to use Set Variable actions to set them. That's kind of doing it the hard way.

[cw-kid]

@toggledbits

For the value in the expression "ps4powerstatus" its either going to be:

200 = ON
620 = OFF

How can I have another expression that will translate those code numbers in to human text that I can then send to Vera / Home Remote ?

Thanks

Understood I have changed it and removed the set variable actions:

EDIT:

Don't think it likes that, I get these error when I press the "Reset" button on the rule.

[toggledbits]

That's right.

Show all the values when you post an error, please.

[cw-kid]

This is what the summary card looks like after hitting the Reset button and then the red alerts come back each time after I have cleared them

Expressions:

Not sure why the alerts are appearing ?

[toggledbits]

No errors there.

[toggledbits]

Have you removed the Set Variable actions?
