HTTPMOD - JSON - ENPHASE

petitpunch · 07 Juli 2022, 12:58:44

Hello,
i'm using Fhem since a while to control my house equipment (ZWAVE+KNX+HUE+ALEXA).

Today, i would like to parse data of my enphase solar panels. I can access to a json page with this data:

Code Auswählen


   {
   "production":[
      {
         "type":"inverters",
         "activeCount":7,
         "readingTime":1657190710,
         "wNow":544,
         "whLifetime":600913
      },
      {
         "type":"eim",
         "activeCount":0,
"measurementType":"production",
         "readingTime":1657190870,
         "wNow":-247.697,
         "whLifetime":0.0,
         "varhLeadLifetime":0.0,
         "varhLagLifetime":0.0,
         "vahLifetime":0.0,
         "rmsCurrent":1.993,
         "rmsVoltage":233.433,
         "reactPwr":237.304,
         "apprntPwr":382.255,
         "pwrFactor":-0.64,
         "whToday":0.0,
         "whLastSevenDays":0.0,
         "vahToday":0.0,
         "varhLeadToday":0.0,
         "varhLagToday":0.0,
         "lines":[
            {
               "wNow":-248.028,
               "whLifetime":0.0,
               "varhLeadLifetime":0.0,
               "varhLagLifetime":0.0,
               "vahLifetime":0.0,
               "rmsCurrent":1.647,
               "rmsVoltage":232.066,
               "reactPwr":237.304,
               "apprntPwr":381.782,
      ../..

(wNow is more than one time in this json but only the first is usefull)

I have used this code to retrieve the value of "wNow" (production in realtime).

Code Auswählen


define ENPHASE HTTPMOD http://192.168.1.161/production.json?details=1 60\

setuuid ENPHASE 62c570b4-f33f-266d-54cd-8d2c41346a820026
attr ENPHASE userattr get01JSON get01Regex getData requestHeader stateFormat
attr ENPHASE enableCookies 1
attr ENPHASE icon measure_photovoltaic_inst
attr ENPHASE reading01JSON production
attr ENPHASE requestHeader1 Content-Type: application/json
attr ENPHASE requestHeader2 Accept: */*
attr ENPHASE room ENERGIE
attr ENPHASE stateFormat production-4 Watts/h

it is working but not clean at all.

this code read too much data :

Code Auswählen


production-1
production-10
production-11
production-12
production-13
production-14
../..
production-4
production-41
produ ../..

I could not log this to do a graph, this too heavy to storage and useless.

Could you help me to select only production-4 ? (wNow).

Other question... could you help me to calculate and display in stateFormat the wNow in Kwh ? (the value is displayed in watts).

Thank you

This is not a reply with a HTTPMOD solution - you might want to consider using JsonMod instead as the source is json format.

Below a raw proposal

Code Auswählen

defmod enphaseJM JsonMod http://192.168.1.161/production.json?details=1
attr enphaseJM interval 0 */2 * * *
attr enphaseJM readingList single(jsonPath('$.production.[3].wNow'), 'wNow', '-?-');;
attr enphaseJM stateFormat { my $ret ="";;\
  $ret .= sprintf("%.3f", (ReadingsNum($name,"wNow",0) / 1000));;\
  $ret .= " kWh";;\
  return $ret;;\
}
attr enphaseJM webCmd reread
attr enphaseJM room ENERGIE

It should generate one reading wNow of the fourth production array element (counting starts at 0).

Interval is every second minute:

Code Auswählen

attr enphaseJM interval */2 * * * *

stateFormat devides wNow by 1000 and shortens to two decimal places:

Code Auswählen

$ret .= sprintf("%.3f", (ReadingsNum($name,"wNow",0) / 1000));;\

JsonMod does not have that many features as HTTPMOD so it can be not the proper solution for your case. But imho it is worth a try.

And, btw, next time please use code tags when pasting code - the #-button above the text input field.

Hello Yersinia,

thank you for your solution.
i have tried it but there is a problem with it.

here is the msg:

It seems that the request is not yet correct, returned status code is 400:

Code Auswählen

http://192.168.1.161/production.json?details=1 (400)
You may need to add httpheaders:

Code Auswählen

attr enphaseJM httpHeader Content-Type: application/json

Code Auswählen

defmod enphaseJM JsonMod http://192.168.1.161/production.json?details=1
attr enphaseJM interval 0 */2 * * *
attr enphaseJM readingList single(jsonPath('$.production.[3].wNow'), 'wNow', '-?-');;
attr enphaseJM stateFormat { my $ret ="";;\
  $ret .= sprintf("%.3f", (ReadingsNum($name,"wNow",0) / 1000));;\
  $ret .= " kWh";;\
  return $ret;;\
}
attr enphaseJM webCmd reread
attr enphaseJM httpHeader Content-Type: application/json
attr enphaseJM room ENERGIE

Do you need to provide credentials?
Can you reach the Json source from a browser as well?

petitpunch · 08 Juli 2022, 13:09:41

Hi, better but the value of wNow is incorrect.
I think this is the result of readingTime perhaps:

readingTime":1657278359,"wNow":1665,"

here is the result displayed:

When you try to set readingsList with complete(); it will show everything - this helps at the beginning:

Code Auswählen

attr enphaseJM readingList complete();;
Then you are able to narrow it down to the values you are interested in; here list of found readings based on Json data you provided:

wNow appears four times under production:

Code Auswählen

2022-07-08 13:13:51   production.1.wNow -889.221

I guess you want the last one? Then you can use the JsonPath for it:

Code Auswählen

attr enphaseJM readingList single(jsonPath('$.production.[1].wNow'), 'wNow', '-?-');;

Complete Device raw:

Code Auswählen

defmod enphaseJM JsonMod http://192.168.1.161/production.json?details=1
attr enphaseJM interval 0 */2 * * *
attr enphaseJM readingList single(jsonPath('$.production.[1].wNow'), 'wNow', '-?-');;
attr enphaseJM stateFormat { my $ret ="";;\
  $ret .= sprintf("%.3f", (ReadingsNum($name,"wNow",0) / 1000));;\
  $ret .= " kWh";;\
  return $ret;;\
}
attr enphaseJM webCmd reread
attr enphaseJM httpHeader Content-Type: application/json
attr enphaseJM room ENERGIE

it's working !
great !
many many thanks to you.

it's not easy to me to parse a json like that.

thank you !!

Hello,

since the new firmware (7) of the envoy-s, i can't read the url anymore.
Enphase has added a login/password to an online url with a redirection to my local interface when the login/password is validated.
here is a project on github for home assistant : https://github.com/jrutski/home_assistant_envoy_d7_fw

is it possible to convert that in fhem ?

Christian83 · 11 April 2023, 09:33:46

Hallo,

ich habe ein Perl Modul zum Auslesen des Enphase Gateways gebaut.
Bei Interessen kann ich es gerne zur Verfügung stellen.

s00rb · 21 April 2023, 19:13:23

Moin Christian,

ich wäre interessiert an dem Modul.
Aktuell gehe ich den Umweg über das Homekit Plugin "Enphase Envoy" um an die Daten meiner Anlage zu kommen und lasse mir die Daten per mqtt an FHEM schicken.
Leider steige ich durch die Datenflut und die API von enphase nicht wirklich durch.

Gruß Mario

Christian83 · 24 April 2023, 08:52:37

Hi Mario,

anbei das Modul.
Edit: Altprogramm entfernt.

define <name> ENPHASE <IPAddr> <username>

username ist die mailadresse im Enlighten System.
Mit set <name> password <password> das Passwort für Enlighten hinterlegen.

get <name> LiveData - dann wird das Envoy ausgelesen.
Danach wird bei positiver Erzeugung aller 60 Sekunden sonst aller 300 Sekunden abgefragt. (Kann über Attribut updateinterval geändert werden).

Bei Fragen einfach melden.

s00rb · 24 April 2023, 18:52:40

Coole Sache!
Hab vielen Dank! Ich werde testen und berichten.

Christian83 · 04 Mai 2023, 14:37:54

Bist du schon zum Testen gekommen?

Passt es? Fehlt was?

wolfganghabenicht · 23 Mai 2023, 13:05:20

Moin,

habe es eingerichet, aber bei mir toggelt es dauerhaft zwischen 'reading token', getting session id' und 'getting token' hin und her.

Ich habe eine Session-ID zurückbekommen, aber der state toggelt weiterhin

Christian83 · 23 Mai 2023, 19:10:33

Zitat von: wolfganghabenicht am 23 Mai 2023, 13:05:20Moin,

habe es eingerichet, aber bei mir toggelt es dauerhaft zwischen 'reading token', getting session id' und 'getting token' hin und her.

Ich habe eine Session-ID zurückbekommen, aber der state toggelt weiterhin

Schalt mal verbose auf 5 und schreib das Log.
Dann sehe ich vielleicht was.
