  Consumption value
Posted by: davidvb - 15.08.2017, 12:40 - Forum: SmartPi - English - No Replies

I see a daily consumption of 5.07 kWh (see top left side - red circle) and a production of 2.14 kWh (green circle).
Why is there a difference with the value shown on the week graph, in this screenshot 5.79 kWh?
In the logs I see that the query uses the UTC-time instead of the local time. In the database every record uses the local (correct) time.
So when I export the database to a CSV-file and I do the math myself, I get different total values.
Can you check this in the code?

  Neue Softwareversion 0.6.3
Posted by: jens - 11.08.2017, 14:54 - Forum: SmartPi - Deutsch - Replies (4)

Hallo,

es gibt eine neue Softwareversion für den SmartPi.

Die wichtigsten Änderungen in Kürze:
- Stabilität
- Start der Benutzerverwaltung (Linuxbenutzer die in der Gruppe smartpiadmin sind, können Einstellungen auf der Weboberfläche durchführen)

Der Download ist unter:
http://blog.enerserve.eu/category/smartp...n-smartpi/
möglich.
Bitte noch nicht das Image verwenden (alte Version).

Am einfachsten ist die Einbindung unseres Repositorys:
Code:

Code:
sudo su
apt install apt-transport-https
wget https://repro.enerserve.eu/packages/Release.key && apt-key add Release.key && rm Release.key
echo "deb https://repro.enerserve.eu/packages jessie main" > /etc/apt/sources.list.d/enerserve.list
apt-get update
apt-get install smartpi

Damit sind Updates in Zukunft ganz einfach möglich.

Viele Grüße Jens Ramhorst

Posted by: jens - 11.08.2017, 14:52 - Forum: SmartPi - English - No Replies

Hello,

I'm proudly to present you a new software version for the SmartPi.

The most important changes:

-fixed stability problems
-begining of usermanagement

The download is available:
http://blog.enerserve.eu/category/smartp...n-smartpi/

Please do not use the image (old version).

The easiest way is to integrate our repository:
Code:

Code:
sudo su
apt install apt-transport-https
wget https://repro.enerserve.eu/packages/Release.key && apt-key add Release.key && rm Release.key
echo "deb https://repro.enerserve.eu/packages jessie main" > /etc/apt/sources.list.d/enerserve.list
apt-get update
apt-get install smartpi

This makes updates more easier in the future.

Best regards Jens Ramhorst

  Direction of current coils
Posted by: davidvb - 10.08.2017, 17:43 - Forum: SmartPi - English - Replies (6)

Since yesterday, after a power failure, the shown power values are inversed. 
My consumption is shown as a negative value, and the production from my solar panels is shown as positive values.
So I needed to switch the direction of the current measurements.
Why is this happening? I connected the current coils over the main leads with the arrows in the direction of my home.


In your documentation there is a drawing of the connections of these coils. You can see that the arrows on the coils are from the left to the right, so in fact from the house to the power net.
Is this correct? Because I suppose the current direction should be from the power net to the house. So I believe the arrows are drawn in the wrong direction.
Since the documentation is very poor about this, give me a clear answer or drawing how to connect the current coils over the wires in a correct way.

  Connection to the inputs
Posted by: muhammadusman94 - 08.08.2017, 09:02 - Forum: SmartPi - English - Replies (1)

I want to get the values of the current and voltage inputs in Python manually. How do I know that which port of the Smart Pi(the ones that are connected to the Raspberry Pi) is connected to which inputs?

  Voltage offset on phase 2 and 3
Posted by: davidvb - 05.08.2017, 15:28 - Forum: SmartPi - English - Replies (7)

Hi,

I installed today my smartpi and tried out the webinterface etc.
But I notice that phase 2 and 3 are always +10V offset with the real values.
See image attached.


This phenomenon is also the case in this article by Elektor:
https://www.elektormagazine.com/news/rev...y-pi/15759


A second remark is that I have installed solar panels on the first phase.
I see on my solar power converter for example 1500-2000Wh generated.
But on my first phase of the smartpi I see values of around -700 W which is quiet off.
The power consumers on this phase are neglectable.

Any solutions?

  Wi-Fi, WLAN bei RPI-3
Posted by: akraehenbuehl - 04.08.2017, 13:09 - Forum: SmartPi - Deutsch - Replies (1)

Kann beim Raspberry Pi 3 anstelle der Ethernet Schnittstelle auch die WLAN Funktion verwendet werden?
Falls ja, muss noch ein Modul etc. aktiviert werden, und wo kann die SSID und der Sicherheitsschlüssel eingestellt werden?

Vielen Dank!

  Einsatz größerer Stromwandler
Posted by: SD-INST - 04.08.2017, 09:57 - Forum: SmartPi - Deutsch - Replies (1)

Hallo,
gibt es die Möglichkeit, größere Stromwandler einzusetzen? Wir würden gerne unsere Maschinen (max. 200A) messen. Es wäre auch kein Problem, dabei das Übersetzungsverhältnis abzuändern. Notfalls könnte man den gemessenen Wert nachträglich z.B. verdoppeln.

Liebe Grüße aus Plauen

  Frequenz, immer wieder Ausreisser bei F3
Posted by: zimberg - 15.07.2017, 12:45 - Forum: SmartPi - Deutsch - Replies (11)

Hallo

Ich konnte den SmartPi soweit problemlos in Betrieb nehmen.

Leider stelle ich bei F3 immer wieder Ausreisser fest, wobei "nur" die Kommastelle massiv hin und her zu springen scheint. Also 5.045, 5034, 507, oder auch mal 501230123123 oder 5.0123123123+e36. 50.01, 50.0 oder 49.99 oder so ist alles im grünen Bereich aber eben nicht 5009024000000000 Hz oder sogar 5.0123123123+e36 oder ähnlich.

"Ausreisser" ist wohl untertrieben, weil meist falsche Werte und zwischendurch dann aber doch wieder gültige Werte angezeigt werden.

Hat jemand dieselbe Beobachtung machen können?
Kennt jemand eine Lösung?

Grüsse

Zimberg

  Undokumentierte API Funktion: Tagessummen
Posted by: etofi - 27.06.2017, 08:06 - Forum: SmartPi - Deutsch - No Replies

Hallo zusammen,

dieser Teil der API ist in der Dokumentation enthalten:


Actual Values:
For example type
Code:
http://<ipaddress:1080>/api/all/all/now
in your webbrowser to get all actual values.
The structure of the URL looks like:
Code:
http://<ipaddress>:<port>/api/<phaseid>/<valueid>/now
Allowed parameters for valueid:

current      Current [A] (available for phase 1,2,3, neutral conductor)
voltage       Voltage [V] (available for phase 1,2,3)
power        Power [W]  (available for phase 1,2,3)
cosphi        cos φ  (available for phase 1,2,3 –  it is important to measure the voltage)
frequency  Frequency [Hz]  (available for phase 1,2,3)
all               Get all Values
 
Allowed parameters for phaseid:
1  Phase 1
2  Phase 2
3  Phase 3
4  only for use with valueid current (current of  neutral conductor)
all  All phases
 
Historical and chart data:
The REST-API can also serve historical data.
For example 
Code:
http://<ipaddress:1080>/api/chart/123/power/from/2016-09-29T00:00:00.000Z/to/2016-09-29T14:00:00.000Z
gives you all measured values of power
from September 29,2016 between 0.00 a.m and 2.00 p.m.
The structure of the URL looks like:
Code:
http://<ipaddress>:<port>/api/chart/<phaseid>/<valueid>
Allowed parameters for valueid:
current           Current [A] (available for phase 1,2,3, neutral conductor)
voltage          Voltage [V] (available for phase 1,2,3)
power            Power [W]  (available for phase 1,2,3)
cosphi            cos φ  (available for phase 1,2,3 –  it is important to measure the voltage)
energy_pos  Energy [Wh] (energy consumption)
energy_neg  Energy [Wh] (energy production)
 
Allowed parameters for phaseid:
1       Phase 1
2      Phase 2
3      Phase 3
4       only for use with valueid current (current of  neutral conductor)
123  All phases


Was nicht drin steht ist dass man mit
Code:
http://<ipaddress>:<port>/api/dayvalues/<phaseid>/<valueid>
auch fertige Tagessummen aus der Historie auslesen kann.

http://<ipaddress>:<port>/api/dayvalues/1/energy_pos/from/2017-06-26T00:00:00.000Z/to/2017-06-27T00:00:00.000Z
liefert beispielsweise den Energieverbrauch auf Phase 1 vom 26.06.2017
