APC UPS Binding

Roi · June 21, 2016, 11:33am

Hello all,

I’m writing this here as I think it is the right sub forum. And might be interesting for others as well - as soon as the problems are solved.

My goal is to monitor two APC UPS devices. I took some information, configuration and scripts from here.

Looks pretty decent but I am stuck with one error message:

2016-06-21 13:24:06.804 [ERROR] [o.o.c.s.ScriptExecutionThread ] - Error during the execution of rule 'USV Handling': The name 'compile(<XFeatureCallImplCustom>)' cannot be resolved to an item or type.

Here’s the content of my configuration files:

Edited the post to English. Sorry, I was somewhere else and somehow thought it is a German forum.

rlkoshak · June 21, 2016, 2:53pm

I see nothing obviously wrong.

Have you logged out sExpr to make sure that you are indeed passing what you think you are passing?

compile is static so the “::” is correct but the error implies that Pattern::compile(String str) doesn’t exist. But it does…

You might try using the fully qualified name for Pattern and see if that works.

Roi · June 21, 2016, 9:38pm

Hi and thank you for your reply.

Sorry, I just get in touch with openHAB. What is the fully qualified name for Pattern?

Thanks and cheers,
Roi

rlkoshak · June 22, 2016, 2:58pm

java.util.regex.Pattern

Roi · June 22, 2016, 9:29pm

Thank you, now I get:

Error during the execution of rule 'USV ATLAN Handling': The name 'java' cannot be resolved to an item or type.

I changed the line to:

ups_pattern = java.util.regex.Pattern::compile(sExpr)

Any idea?

rlkoshak · June 23, 2016, 2:54pm

Maybe you need to import it? This is weird as there is nothing obviously wrong with it as originally written. Grasping at straws.

Roi · June 27, 2016, 11:00am

I tried:

import java.util.regex.Pattern

Now:

No idea… :-/

Roi · June 27, 2016, 2:25pm

It works now!!!

Here’s the code (just the first part before the rule definition, which I did not change):

Not sure what type of APC you have or what the output of that script looks like but I just made this items file yesterday. My needs are pretty simple, I want to use the external temperature and humidity sensor on the UPS to monitor the environment in my equipment closet. Then turn an exhaust fan I installed in the closet on or off at certain temperatures and/or during times of increased infrastructure activity (specifically CPU, disk IO, or 3+ simultaneously active audio zones). I wasn’t able to find the OID for the humidity but from my testing of the closet humidity isn’t a problem in my case as it draws conditioned air from the hallway. I was able to get the temperature to openhab working so quickly I added other items just for completeness. Powerchut and VMware does a pretty good job at automating shutdown and startup so I’ll probably never actually use these extra items. In any event these items may help you or someone else who finds this thread.

Don’t know why but the forum formatting added a “>” before all the items. Obviously you’ll have to remove those.

Roi · June 28, 2016, 10:46am

Hi Kerwin,

thanks a lot! I’m sure this will be of use for lots of people dealing with UPS devices. For me it is not relevant at the moment as my UPS devices only have USB connection, no LAN interface. But I will keep this in mind for the next generation of UPS devices here.

Cheers,

Hello everybody, again…

I just upgraded to openHAB 2 and the rule does not work anymore. Now I get this error in the log:

2017-04-21 12:01:36.302 [ERROR] [.script.engine.ScriptExecutionThread] - Rule ‘USV Handling’: The name ‘.state’ cannot be resolved to an item or type.

The error is there for both versions of the code (post 1 and my modified version in post 9). As I am really stuck here I would be very happy if someone can take a look and maybe point me into the right direction.

Thank you, regards,
Roi

rlkoshak · May 4, 2017, 6:49pm

The error implies that you have a reference to an Item that doesn’t exist or perhaps is NULL. Look very carefully at all the Item names and make sure there isn’t a typo. Designer is great for checking syntax. Then check the states of all the referenced items. If any are NULL (will show up as “-” on the sitemap) that might be a problem.

I’m grasping at straws. If it worked in OH 1.x is should work in 2.x as written.

Roi · May 9, 2017, 9:23am

Thank you, I think you and the Designer put me on the right path.

I had to change org.openhab.core.library.items into org.eclipse.smarthome.core.library.items - now it works again!

rossko57 · May 9, 2017, 10:35am

This is pointed out in the migration tutorial that you may have missed.
In fact
org.openhab.core.library.items.StringItem xxx
should become
StringItem xxx
in OH2

Roi · May 9, 2017, 10:43am

@rossko57 Thank you for bringing that to my attention. I did miss that, but I saw the page weeks ago… I’m sure I missed more stuff as I do not get the old S300TH binding up and running…

jo47011 · August 7, 2017, 10:15am

Hi All,

here is a little bit more generic solution for openhab2:

My script apc_dump_log just dumping only the requested key/value pairs (json):

#!/usr/bin/python

import json
import subprocess # needed for apcaccess call

request = ('TONBATT' , 'BCHARGE' , 'STATUS' , 'LINEV', 'LOADPCT', 'BATTV' , 'TIMELEFT' ,'MBATTCHG' , 'MINTIMEL' , 'LASTXFER', 'DATE')
# include those for debugging so the openhab rule fires on every reading
#     , 'DATE' ,  'END APC' )

result = {}

# get status from apc-ups
res = subprocess.check_output("/sbin/apcaccess")
for line in res.split('\n'):
    (key,spl,val) = line.partition(': ')
    key = key.rstrip()   # .lower()
    if key in request :
        val = val.strip()
        result[key] = val

print(json.dumps(result, indent=0))

Here is my item file apc.items:

/* APC UPS */

Group APC  (All)
Group APC_Values  (All)

String APCRaw "APC: [%s]"  {channel="exec:command:apc:output"}
DateTime APCLastExecution "Status am: [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]" (APC) {channel="exec:command:apc:lastexecution"}

String APC_STATUS	"STATUS   [%s]"	(APC,APC_Values)
String APC_LINEV	"LINEV    [%s]"	(APC,APC_Values)
String APC_LOADPCT	"LOADPCT  [%s]"	(APC,APC_Values)
String APC_BATTV	"BATTV    [%s]"	(APC,APC_Values)
String APC_BCHARGE	"BCHARGE  [%s]"	(APC,APC_Values)
String APC_TIMELEFT	"TIMELEFT [%s]"	(APC,APC_Values)
String APC_MBATTCHG	"MBATTCHG [%s]"	(APC,APC_Values)
String APC_MINTIMEL	"MINTIMEL [%s]"	(APC,APC_Values)
String APC_TONBATT	"TONBATT  [%s]"	(APC,APC_Values)
String APC_LASTXFER	"LASTXFER [%s]"	(APC,APC_Values)

my apc.rules:

rule "APC UPS Handling"
when
   Item APCRaw changed
then
   val String json = (APCRaw.state as StringType).toString

   APC_Values.members.forEach [ value |
      var String name = value.name.replace('APC_','$.')
      value.postUpdate(transform("JSONPATH", name, json).replaceAll('"',''))
   ]
end

and finally my exec.things:

Thing exec:command:apc [command="/etc/openhab2/scripts/apc_dump_log", interval=60, timeout=5]

Ally ou need to add to your sitemap is a group item:

	Group item=APC label="APC USV" icon="energy"

You need the exec binding and the jsonpath transformation. Of course more time could be invested in beautifying the items, parsing numbers etc. But still I hope the approach may help one or the other.

Happy hacking

@jo47011, very nice solution! Thank you!

I need to take a closer look into it some time. At the moment I am focusing on getting everything up and running in OH2 and doing some documentation as I forget stuff without it. I put my current APC UPS solution for OH2 into my Git repo, here it is, maybe also interesting for others: https://git.hot-chilli.net/msebald/openhab/src/master/apcups

Thanks for posting the method to access apcupsd - it worked right out of the box for me.

For my setup, I simplified it a bit and created a single Thing with an associated Item for each of the parameters I’m interested in for the UPS (example for STATUS below). I monitor several parameters and each one can be done at different time intervals (or triggered by rules? but not there yet).

But clearly parsing the full output of apcaccess is what’s needed for a solid binding so thanks for sharing.

ups.things:
Thing exec:command:UPSstatus [command="/sbin/apcaccess -p STATUS", interval=60, timeout=2]
…
ups.items:
String UPS_Status “UPS Status: [%s]” (gUPS) {channel=“exec:command:UPSstatus:output”}
…
