MiniJoule / Enecsys Wechselrichter auslesen

[Guest]

Hi,

Ich habe eine kleine Photovoltaik-Anlage von MiniJoule.
Die Enecsys-Wechselrichter senden die aktuellen Messdaten per Zigbee
an das Enecsys Gateway, einem kleinen Kasten mit LAN-Anschluss.
Das Gateway bereitet die Daten auf und sendet sie weiter an den
Enecsys-Server, wo man auf einer Webseite eine (leider Flash-basierte)
Webseite aufrufen kann.

Optimal wäre es natürlich, die Daten direkt aus dem Gateway abzurufen,
aber ich habe das Protokoll noch nicht verstanden.
Da kommen Zeilen wie diese:
WS=F4_3BQCaxjQAAJTgIQEAAAGGFDADiAABDAD6A6QyAOMkAmQACwAA9A
WZ=Ya81dwCaxjQAAJUpIQEAAAHdClNhrzV3AJrGNEg=60,S=2000007009
WS=QY_3BQCaxjQAAJVKIQEAAAGHFDADiAABFQEDA6cyAOMlA3gACwAA6B
WZ=Ya81dwCaxjQAAJVWIQEAAAHeClNBj_cFAJrGNEg=6F,S=2000007009
WS=F4_3BQCaxjQAAJVYIQEAAAGHFDADiAABFAECA6YyAOQlAmQACwAAB4

Hat jemand eine Eingebung, was das bedeuten könnte? Es handelt sich
jedenfalls scheinbar NICHT um BASE64, auch wenns ein bisschen so
aussieht.

Auf jeden Fall ist es mir gelungen, die Flash-Webseite zu analysieren,
dabei kam raus, dass Enecsys ein ASP.NET-basiertes SOAP-Interface
verwendet.
Ich habe ein Shell-Script geschrieben, mit dem man die Daten auslesen
und in FHEM verwenden kann.
Hat jemand Lust, aus dem Script ein FHEM-Modul zu machen? Das wäre
eleganter! Ich rufe das Script derzeit mit einem Timer alle zwei
Minuten auf:
define pv_timer at +*00:02:00 "/Users/akw/enecsys.sh"

Hab das Script ins Wiki gestellt:
http://www.fhemwiki.de/wiki/Enecsys_Monitoring_System


Hat noch jemand Enecsys - Hardware und potentiell Interesse an der
Weiterentwicklung?

Ciao, Arno

I recently tried to deal with this (unsuccessfully) with another dutch
Enecsys user. I don't use FHEM, but would like to tap into the gateway to
get data in a little more detail. I ran into this thread while googling
around.

Here some discussions addressing the issue

Tweakers.net<http://gathering.tweakers.net/forum/list_message/38773473#38773473>
Navitron<http://www.navitron.org.uk/forum/index.php?PHPSESSID=nuvf6b56qn0unpdps0v326rct5&topic=14579.msg176292#msg176292>

Things we found
WZ=i7c1dwC.. lines seem to be from the gateway, number in the end is
gateway serial+1
Then the WS=lines are most likely from the inverters.
Each inverter sends lines that start with a unique prefix, which probably
encodes some sort of serial/ID string. I have 4 inverters, the are 4 unique
prefixes, plus a prefix for the gateway.

The gateway also reports de Zigbee adress of the inverters as something
like 05F6F017, which in decimal matches the serial number as printed on the
inverters.

Here are some of my strings

WS=-vL2BQCaxjQAAN7HIQEAAADnFDADiAAAlwCKA5EyAOUxAiMADgAAB4
WZ=i7c1dwCaxjQAAN7TIQEAAAS8ClP68vYFAJrGNEg=00,S=2000XXXXXX

WZ=i7c1dwCaxjQAAN9nIQEAAAS_ClMX8PYFAJrGNEg=35,S=2000XXXXXX


However, no luck in decoding the string.

Your script seems nice though, I will try to get it to run on my QNAP
NAS.and log to a file or otherwise (maybe even FHEM )

Cheers

Yes!

 

Most of the discussion ended up in a thread on the Navitron forum

 

http://www.navitron.org.uk/forum/index.php/topic,18276.90.html

 

I have written a simple perl script that pulls in data, and another guy
wrote a .NET windows app that does the same and pushes data to PVOUtput.
(Aloaha solar)

 

In a nutshell, the current interpretation is posted below. Not all is known,
especially the timekeeping is not entirely clear to me (but we can timestamp
with system time)

Some uncertainties remain, but I think we have gotten pretty close. We now
have access to power, energy produced,DC volt, AC volt, DC amps, efficiency,
invertertemperature, AC frequency.

 

I hope this is of use to you.

 

Best,

 

Martijn

This is what I found out. Numbers are expressed in base64 instead of
decimal.


WS=F_D2BQCaxjQAAIGkIQEAAADRFDADiAAAdABpA4kxAOcbAM4ANQAA94

   F_D2BQ                                                   System ID
              AAIG                                          Timestamp,
base64, unit: 30s after 9:00 or 21:00
                      AAADR                                 Power related,
probably voltage. base64, unit unknown, divide by 7 to get reasonable V
                                     BpA4k                  Power related,
probably amps, base 64, unit unknown, divide by 8 x 10E6 to get reasonable A
                                          xAOc              AC related,
bin64 related. Goes to AAAA if no grid. could be xA=V, Oc is freq?
         Caxj                                               Unknown, always
there. Year, serial prefix, model inverter?
                  kIQE                                      Unknown. k
varies, IQE constant.
                           FDADi                            Unknown
                                AAA                         Suspect error
states. AAA=feeding grid, AMA/AEA error states undervoltage, no grid
                                              bAM4ANQAA94   Unknown. quite
variable. Constant for a few minutes, different between inverters.
                                             
Missing: datestamp, AM/PM marker (time counter resets twice daily), AC power
(unlikely), inverter temperature.

Auf English, da mein Deutsch nicht so gut mehr ist.

I recently tried to deal with this (unsuccessfully) with another dutch
Enecsys user. I don't use FHEM, but would like to tap into the gateway to
get data in a little more detail. I ran into this thread while googling
around.

Here some discussions addressing the issue

Things we found
WZ=i7c1dwC.. lines seem to be from the gateway, number in the end is gateway
serial+1
Then the WS=lines are most likely from the inverters.
Each inverter sends lines that start with a unique prefix, which probably
encodes some sort of serial/ID string. I have 4 inverters, the are 4 unique
prefixes, plus a prefix for the gateway.

The gateway also reports de Zigbee adress of the inverters as something like
05F6F017, which in decimal matches the serial number as printed on the
inverters.

Here are some of my strings

WS=-vL2BQCaxjQAAN7HIQEAAADnFDADiAAAlwCKA5EyAOUxAiMADgAAB4
WZ=i7c1dwCaxjQAAN7TIQEAAAS8ClP68vYFAJrGNEg=00,S=2000XXXXXX

WS=-vL2BQCaxjQAAN8_IQEAAADoFDADiAAAlgCJA5EyAOUxAiwADgAA4C
WZ=i7c1dwCaxjQAAN9EIQEAAAS-ClOLtzV3AJrGNEg=24,S=2000XXXXXX
WS=F_D2BQCaxjQAAN9aIQEAAAG5FDADiAAAnACOA44yAOUwA9UAGwAA1B
WZ=i7c1dwCaxjQAAN9nIQEAAAS_ClMX8PYFAJrGNEg=35,S=2000XXXXXX


However, no luck in decoding the string.

Your script seems nice though, I will try to get it to run on my QNAP
NAS.and log to a file or otherwise (maybe even FHEM )

Cheers

Hi,

Ich habe eine kleine Photovoltaik-Anlage von MiniJoule.
Die Enecsys-Wechselrichter senden die aktuellen Messdaten per Zigbee
an das Enecsys Gateway, einem kleinen Kasten mit LAN-Anschluss.
Das Gateway bereitet die Daten auf und sendet sie weiter an den
Enecsys-Server, wo man auf einer Webseite eine (leider Flash-basierte)
Webseite aufrufen kann.

Optimal wäre es natürlich, die Daten direkt aus dem Gateway abzurufen,
aber ich habe das Protokoll noch nicht verstanden.
Da kommen Zeilen wie diese:
WS=F4_3BQCaxjQAAJTgIQEAAAGGFDADiAABDAD6A6QyAOMkAmQACwAA9A
WZ=Ya81dwCaxjQAAJUpIQEAAAHdClNhrzV3AJrGNEg=60,S=2000007009
WS=QY_3BQCaxjQAAJVKIQEAAAGHFDADiAABFQEDA6cyAOMlA3gACwAA6B
WZ=Ya81dwCaxjQAAJVWIQEAAAHeClNBj_cFAJrGNEg=6F,S=2000007009
WS=F4_3BQCaxjQAAJVYIQEAAAGHFDADiAABFAECA6YyAOQlAmQACwAAB4

Hat jemand eine Eingebung, was das bedeuten könnte? Es handelt sich
jedenfalls scheinbar NICHT um BASE64, auch wenns ein bisschen so
aussieht.

Auf jeden Fall ist es mir gelungen, die Flash-Webseite zu analysieren,
dabei kam raus, dass Enecsys ein ASP.NET-basiertes SOAP-Interface
verwendet.
Ich habe ein Shell-Script geschrieben, mit dem man die Daten auslesen
und in FHEM verwenden kann.
Hat jemand Lust, aus dem Script ein FHEM-Modul zu machen? Das wäre
eleganter! Ich rufe das Script derzeit mit einem Timer alle zwei
Minuten auf:
define pv_timer at +*00:02:00 "/Users/akw/enecsys.sh"

Hab das Script ins Wiki gestellt:
http://www.fhemwiki.de/wiki/Enecsys_Monitoring_System


Hat noch jemand Enecsys - Hardware und potentiell Interesse an der
Weiterentwicklung?

Ciao, Arno
