The smartpi server software creates a webserver with access on the default port 1080 (changeable).
Is it possible to access the smartpi using the https protocol in place of the default http?

I downloaded the new image with version 0.9.1, but I cannot write it on a SD card.
I tried several SD cards of 16 Gbyte, but when I write the image on the SD card, it always said that I need more space.
I tried writing with Win32DiskImage and Etcher, they gave the same result.
It seems that most SD cards or not really 16 Gbyte, but only 15,5 Gbyte.
Is it possible to make the existing image smaller (for example 15 Gbyte) so it will fit any SD card of 16 Gb?

Dear,
I the case of a 1-phase system with 3 or 4 current measurement, I know I have to power the SmartPi with N and L1 supplied, but how can I associate the I2-4 with the voltage of L1 ?
Can I connect L1 also on L2 and L3 on the SmartPi ?
Thank you,
Pierre

| Software Installation Problems |

Good day to the Forum!
My SmartPi has been down ever since the introduction of Node Red.
When I installed the update, several months ago, the install did not go well and my SmartPi has never recovered.
My SmartPi consists of:
Raspberry Pi 3 Model B
The original Kickstarter SmartPi board.
This past weekend I tried again to install the new software version and here is my experience.
I did a fresh install of Raspbian Stretch with Desktop from the Pi site.
I enabled SSH and VNC.
The install went well and worked as expected.
Then I followed the instructions at:
SmartPi Installation
and installed the .deb archive for stretch.
Now the problems:
1 - When Installed the archive, it stopped loading saying that "npm" was not installed.
OK, so I went online and installed it. That cleared that error on the next install attempt.
(that was a real experience)
2 - The install indicated that a directory was missing "init.d".
OK, I manually created that directory and the install completed.
I noted the following problems:
1 - SmartPi does not start at boot. I have to start it manually using the instructions at SmartPi Installation.
2 - The server is not working correctly, it will only serve the page ONCE, then I have to reboot and restart manually.
The data it dis show looked fairly correct.
Clearly, I have not installed the new version correctly.
I am out of ideas, and my skill with the Pi is very limited and I need help.
I would appreciate a very clear and detailed instruction set to reinstall my SmartPi software correctly.
The new software looks very promising and I and anxious to get my SmartPi going again.
Cheers,
NoSpark

Code: sleep(sleeptime) # warten
#print ("warten 2: Schleife")
file = open('/var/tmp/smartpi/values')
messwerte = file.readlines()
file.close
print ("Messwerte: ", messwerte)
print (" ")
for line in messwerte:
wertnr = 0
wert = line.split(";")[wertnr] # Messwert extrahieren
#wert[10] = ";"
wert0 = wert.split(" ")[0]
wert1 = wert.split(" ")[1]
wert = wert0 + "; " + wert1
werttxt = "> Datum : " + wert + " Rohdaten"
print ( werttxt )
mess[wertnr] = " " + wert
for wertnr in range(1, 7):
wert = line.split(";")[wertnr] # Messwert Strom
wertf = float(wert)
wertf = wertf / wertkorr[wertnr]
werts = '%6.2f'%wertf
mess[wertnr] = werts
werttxt = "> Wert" + '%2.0f'%wertnr + " : " + werts + " A Strom " + wert
print ( werttxt )
ich versuche die Daten zum Beispeil Leistung mit Hilfe von Python auszulesen allerdings weiß ich nicht wo mein Fehler im Programm ist. Ich bin ei Anfänger mit dem Raspberry und SmartPi. Ich wurde mich über eure Hilfe freuen. Zur Zeit versuche ich nur den Strom anzuzeigen allerdings klappt es nicht. Ich hab mir das Programm im Forum als Hilfe genommen, da dort ebenfalls versucht wurde mittels Python auszulesen.
Bedanke mich im Voraus

| API Abfrage - Abfrage URL ergibt nicht den übereinstimmenden Wert |

Ich frage zur Auswertung des über den Tag bzw. Monat aufkommenden Stromverbrauchs extern über die API den Verbrauch ab.
Dabei habe ich das Problem, dass ich folgende API-Abfrage mache:
Code: https://10.10.1.71/api/dayvalues/123/energy_pos/from/2018-04-11T00:00:00.000Z/to/2018-04-11T23:59:59.999Z
dabei erhalte ich die Ausgabe von
Code: [
{"key":"energy_pos_1","values":[{"time":"2018-04-11T23:59:25+0200","value":1942.9053},{"time":"2018-04-12T01:59:27+0200","value":135.687}]},
{"key":"energy_pos_2","values":[{"time":"2018-04-11T23:59:25+0200","value":4315.477},{"time":"2018-04-12T01:59:27+0200","value":151.05037}]},
{"key":"energy_pos_3","values":[{"time":"2018-04-11T23:59:25+0200","value":3647.5513},{"time":"2018-04-12T01:59:27+0200","value":205.31183}]}
]
Wie dabei zu sehen, stimmen die Zeiten bei mir nicht überein. Es werden um zwei Stunden versetze Zeiten ausgeben. Das hat bestimmt etwas mit der Zeitzone zu tun. Wie bekomme ich das hin, dass die API-Zeit mit der Datenbank-Zeit (???) übereinstimmt und ich die aktuellen Werte entsprechend ausgegeben bekomme (auch nach Sommer-/Winterzeit Umstellung)  .
Bei:
Code: https://10.10.1.71/api/dayvalues/123/energy_pos/from/2018-04-10T22:00:00.000Z/to/2018-04-11T21:59:59.999Z
Code: [
{"key":"energy_pos_1","values":[{"time":"2018-04-11T23:59:25+0200","value":2079.196}]},
{"key":"energy_pos_2","values":[{"time":"2018-04-11T23:59:25+0200","value":4462.9453}]},
{"key":"energy_pos_3","values":[{"time":"2018-04-11T23:59:25+0200","value":3855.8508}]}
]
---------------------- Edit Dashboardvergleich gelöscht.
Eine aktuelle Abfrage über die API bis Tagesende ergibt als Ausgabe für den letzten Wert:
Code: {"time":"2018-04-12T11:47:35+0200","value":855.0059}
Stehe ich mit den Zeiten auf Kriegsfuß? Hat jemand eine Erklärung / Lösung für mich?
Dankende Grüße
Gregor
