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

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 Yves Schmidt

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
