Shelly 1PM as PV Inverter in VenusOS

Hi community,

inspired by the dbus-shelly-3em-smartmeter from @fabian-lauer, I created my own dbus-shelly-1pm-pvinverter GitHub project to use a Shelly 1PM in VenusOS as a PV inverter. Maybe some one else find it useful.

Here are some screenshots from my current setup with these three Shelly devices (2x1PM and 3EM):

Great work! :)

Does this script support the Shelly Plug S as a backup generator?

@vikt0rm Very nice work. But I intend to use the 1PM for AC input-monitoring. Can I use your implementation for that?

Hello, thank you. This works very well. Is there a way to add a 2nd and 3rd Shelly1PM as an inverter to VenusOS. Is it possible to run the script more often?

Thanks very much. Sorry for my bad English

Hi @Qualle888, yes you can install more than one instances of the script. In my setup I use two instances for example.

You can copy your first instance by simply logging in to your venus os over ssh and run:

cp /data/dbus-shelly-1pm-pvinverter /data/dbus-shelly-1pm-pvinverter2

Configure the second instance and run

/data/dbus-shelly-1pm-pvinverter2/install.sh

Hello,

can you also build something like this, e.g. to integrate the Sonoff POW device with Tasmota?

Hi elko,

I don‘t have these devices you mentioned in my setup. But I guess when there is an API then it should be no problem to adapt my code to fit your needs. You can simply create a fork of my project an do your adaptions on your fork.

Hi @elko,

I use this MQTT-dbus driver to generate a "pvinverter" and write with Tasmota via rules into the corresponding topics.
Best regards,
Sebastian

Hello @vikt0rm,

thanks a lot for your script.
Is it also possible to install it on a Multiplus II GX?
I have tried to do that but i cannot see my Shelly 1 PM in the device list.
How can i check if the service is running correctly or where can i find the logfiles?

Thank you in advance.

I have it installed on a Multiplus II GX!

Connect through it with the internal IP

The follow this: https://www.victronenergy.com/live/ccgx:root_access

Step 1 and 2. Then use Putty (common for ssh access) and login (root and your password you set) and run the script provided by viktrom. It will install.

Then use the command 'nano /data/dbus-shelly-1pm-pvinverter/config.ini ' and change the ip adress to the ip of the shelly and login if needed.

After a few seconds the device will show in your victron device list :)

Hello @vikt0rm,
do you know which "dbus channels" are minimal necessary for a pvinverter to work?
I use this MQTT Devices driver to generate a pvinverter, but it won't work with a second one. VRM don't calculate the phases correctly, but replaces the first one with the second one.
Thanks, Sebastian

Hi all

as i connected my pv on acout1 as the only Device i think about using this Script and taking the acout values directly from dbus.

currently my only idea is to Grab them over mqtt from the venus. can anyone tell me if i can get them directly from dbus in this Script?

Would it also be possible to display individual loads instead of pv inverters with several Shelly 1PMs in the VRM?

e.g. washer, dryer, stove, oven...

Unfortunately I cannot get any further and could not find the place in the script where the type is specified.

I could also imagine that the sign for a consumer must also be reversed for "/Ac/Power" and "/Ac/Energy/Forward"?

It would be ideal if it could also be specified in the config.ini whether it is a generator or a load.


Ich komme leider auch nicht weiter und konnte auch nicht die Stelle im Skript finden, wo der Typ festgelegt wird.

Außerdem könnte ich mir vorstellen, dass auch das Vorzeichen für einen Verbraucher umgekehrt werden muss bei "/Ac/Power" und "/Ac/Energy/Forward"?

Optimal wäre es, wenn in der config.ini festgelegt werden könnte, ob es sich um einen Verbraucher oder Erzeuger handelt.

Hallo, ich habe 2 Shelly 1PM als PV Inverter eingeunden und diese werden auch sofort auf der Console und im VRM angezeigt. Allerdings fehlt bei mit im VRM und auch in der Console die Anzeige der Phase. Hier in den Beispiel Fotos werden die Phasen mit angezeigt.
Die Config Datei ist korrekt ausgefüllt. An was kann das liegen?
In der Detailansicht in der Geräteliste wird die Phase korrekt angezeigt.

I have now read something and experimented a lot.

Unfortunately, Victron does not have a load as a "servicename" (e.g. com.victronenergy.load), but only the service names specified in the D-Bus API, e.g .: com.victronenergy.charger, com.victronenergy.inverter, com.victronenergy.battery, com.victronenergy.pvinverter, ...

Depending on the service name, the paths are specified here that can be filled with values, e.g. "/Ac/Power" or "/Ac/Current" at "com.victronenergy.pvinverter".

So I tried it as a PV inverter and transmitted the values negatively. Unfortunately, however, all PV inverters are added and not listed individually, which did not lead to the desired result.

I also tried "com.victronenergy.system" and "com.victronenergy.vebus". Unfortunately without success. These service names were not listed as other independent devices.

However, I have now rewritten RalfZim's script and adapted it to my needs. So my Fronius Smart Meter is now displayed as a standalone device:

1655370352404.png


Ich habe mich nun in die Materie etwas eingelesen und viel experimentiert.

Leider gibt es seitens Victron keinen Verbraucher als "servicename" (z.B.: com.victronenergy.load), sondern nur die in der D-Bus API angegebenen service names, z.B.: com.victronenergy.charger, com.victronenergy.inverter, com.victronenergy.battery, com.victronenergy.pvinverter, ...

Je nach service name sind dann auch hier die Pfade vorgegeben, die mit Werten gefüllt werden können, z.B. "/Ac/Power" oder "/Ac/Current" bei "com.victronenergy.pvinverter".

Also habe ich es doch als PV-Inverter versucht und die Werte negativ übermittelt. Leider werden dadurch aber alle PV-Inverter addiert und nicht einzeln aufgeführt, was nicht zum gewünschten Ergebnis führte.

Ich habe mich auch an "com.victronenergy.system" und "com.victronenergy.vebus" versucht. Leider ohne Erfolg. Diese service names wurden nicht als weitere eigenständige Geräte aufgeführt.

Allerdings habe ich jetzt das Skript von RalfZim umgeschrieben und an meine Bedürfnisse angepasst. Somit wird jetzt auch mein Fronius Smart Meter als eigenständiges Gerät angezeigt:

Moin Moin,


Kannst du mir (oder hier der Community) das angepasste Script zukommen lassen?

Ich habe folgendes Problem:

Setup: Multiplus 2, Raspi mit Venus OS, PV-Inverter, Shelly 1PM als Leistungsmesser an PV-Anlage, Batterie, .... alles läuft soweit.

Gestern mit dem Script hier den Shelly ins Venus-System eingebunden, leider wird der Wert der PV-Anlage als positiver "Verbraucher" angezeigt und zum Hausverbrauch (AC-loads) addiert und somit funktioniert die Einspeise-/Batterielade-/-Entladeregelung nicht.

Habe mir das Script hier mal angeschaut und würde jetzt folgende Zeilen im Script anpassen:

# send data to DBus

self._dbusservice[f'/Ac/{phase}/Voltage'] = voltage

self._dbusservice[f'/Ac/{phase}/Current'] = current

self._dbusservice[f'/Ac/{phase}/Power'] = power

self._dbusservice[f'/Ac/{phase}/Energy/Forward'] = energy / 1000 / 60

ändern zu:

# send data to DBus

self._dbusservice[f'/Ac/{phase}/Voltage'] = voltage

self._dbusservice[f'/Ac/{phase}/Current'] = (-1)** current

self._dbusservice[f'/Ac/{phase}/Power'] = (-1)** power

self._dbusservice[f'/Ac/{phase}/Energy/Forward'] = (-1)** energy / 1000 / 60

Mithilfe eines Freundes habe ich den Shelly Plus 1PM zum laufen gebracht. Die Rest api zu den Plus Geräten ist geändert worden. Die Doku auf Github ist allerdings noch nicht geupdatet.
https://github.com/MaKess/dbus-shelly-1pm-pvinverter

Allerdings hatte ich das Problem das der Shelly Plus sehr wärmeempfindlich ist und sich immer wieder resettet. Das heißt der Shelly rebootet mehrmals am Tag und somit der Wechselrichter auch. Ich habe im Shelly eine Auto on Timer auf 0,1s eingestellt damit ich den Wechselrichter auch bei Stromausfall sofort wieder an geht. Zusätzlich habe ich das Problem, dass der Max power protection immer wieder an geht obwohl ich es deaktiviert habe. Habt ihr beim Shelly 1PM auch Überhitzungsprobleme?

Hallo elektrowolf, habe selbst versucht die "dbus-shelly-1pm-pvinverter.py" soweit zu bearbeiten das es mit der "Shelly plus 1pm" läuft. Leider keinen Erfolg. Die Parameter die z.B. http://ip_adresse/rpc/Shelly.GetStatus beim Shelly plus 1pm raushaut, unterscheiden sich leider zu sehr, als das ich dort einen Ansatz finde. Deine modifizierte dbus-shelly-1pm-pvinverter.py würde mich interessieren. Kannst Du mir diese zukommen lassen?

If you are measuring the power produced by a PV inverter connected to the Shelly, then it's classed as a PV inverter meter in Venus.

Hello, thank you for this nice tool!


I have two inverters running: One Fronius, which is supported directly and another one (hoymiles), running on that shelly. With this tool, I can see the Shelly-PV in the device list in the remote console, but in VRM it seems that the output power of the Shelly-PV is being added to the Fronius one.


So when the Fronius generates 1700W and the Shelly-PV is reporting 80w, The value for the Fronius will be shown with 1780w on VRM. Is there a way to have two separate PV Inverters in VRM?

Screenshots:
("Dach" is the Fronius, "BalkonPV" is the hoymiles with shelly)

Hi,

du musst die erste installation kopieren zu pvinverter 2, 3 usw.

dann in der jeweiligen config.ini die Deviceinstance ändern. z.B. 42, 43 usw.

wenn alle unter der gleichen Instance laufen, können sie nicht gefunden werden

Danke für die tolle Arbeit hier und in den anderen Shelly/Victron-Gits


Ich habe einen Shelly 3EM, einen Shelly EM und einen Shelly1PM in meinem System laufen.

- 3EM für Grid-Messung

- EM für Messung der PV-Anlage und

- 1PM für das Balkonkraftwerk

Habe mit den Skripten hier (für 1PM) und für 3EM und EM die Systeme wie folgt eingebunden:

- 3EM als grid auf Pos 0

- EM als pv-inverter auf Pos 0

- 1PM als pv-inverter auf Pos 1

Komisch an der Sache ist, dass der 1PM egal welche Position ich ihn setze immer auf "grid" (wenn Pos0) oder auf kritische Lasten (wenn Pos1) aufaddiert wird. d.h. ich produziere 600W, mit dem Balkonkraftwerk, diese werden aber nicht genutzte um Akku zu laden, oder einzuspeisen, sondern als kritische Last gedeutet und entsprechend aus der PV-Anlage oder dem Netz bedient....

Hat da jemand einen Workaround? Finde nichts im Code, das darauf hindeutet.


Gruß

Hallo zusammen,

ich habe mir das Script von viktr0m geschnappt und für den Shelly EM adaptiert... Vielen dank dafür an viktr0m!

Fall interesse besteht, zu finden ist das EM Script hier: https://github.com/Eddy0815/dbus-shelly-em-pvinverter

Evtl. hilft es jemandem weiter...

@brekkis wenn du magst, kannst du es ja mal mit deinem EM Script vergleichen? Meine Variante läuft erst seit gestern, kann also noch nicht sagen, ob alles korrekt ist.

Grüße

hi @Kampfiltis : nice addition to the Shelley script series! I have been using the version of @vikt0rm and it is working great so far!


Could you describe which changes you made exactly to get the script for the EM version?

I am looking to make adaption for the Shelly Pro 3EM, as a grid meter.


Maybe also an idea to get the 'role' ( self._dbusservice.add_path('/Role', 'pvinverter')) value, which is hard coded now, to the .ini file so users can easily set it to grid/load etc?


Keep up the good work!

@Kampfiltis: Vielen Dank dafür... funktioniert soweit. Nur eine Frage hierzu: Der pv-inverter wird mir zwar im vrm in der Übersicht mit Watt gezeigt und in der remote console sehe ich auch Leistung, Strom und Spannung. Leider wird der Wert im VRM Portal aber nicht unter "Solar" in die Kalkulationen der kWh einberechnet. Ist das bei dir auch so bzw. weißt du hierfür eine Lösung?

Das hatte ich auch. Der Grund war, dass der Sensor falsch herum montiert war. Der Wert wurde im VRM positiv angezeigt, in der Shelly App aber negativ. Ich haben ihn umgedreht, seitdem läuft die Aufzeichnung im VRM.

Hi Sebastian, freut mich, dass du meine Adaption des Scripts verwendest... Bei mir läuft es einwandfrei, auch die Anzeige im VRM läuft wie es soll... Evtl. setzt du das VRM Portal einmal zurück, komplette Daten löschen und dann Venus neu in VRM aufnehmen. Anfangs während der Entwicklung hatte ich teilweise seltsame Anzeigen im VRM, die nach einem Löschen der Daten behoben wurden... Bei mir sieht es jetzt im Portal so aus:

Eine weitere Frage hätte ich noch:
Der Shelly EM hat zwei Eingänge, mit denen man auf der selben Phase zwei Messungen vornehmen kann. Wäre es möglich, auch den zweiten Kanal zu aktivieren. Das würde mir eine Menge Hardware Kosten für Shellys sparen.

I use a 1PM-Plus, but it has low WiFi reception. I asume therefore ist is getting lost within the Victron-Dashboard. Is there a way to restart it automaticly every hour or so? How can I start the connection / the service "by hand"?


OK, I could find the answer:

Inside the installed folder e.g.:

/data/dbus-shelly-1pm-pvinverter01

is a script to restart the service: restart.sh

This can be called by cron for example in the early morning.

crontab -e

There you can install a job to do it. (attention, it uses VI, find the keycodes elsewhere)

the line for crontab is then:

00 02 * * * /data/dbus-shelly-1pm-pvinverter01/restart.sh

So it will restart the script every day at 2:00 AM

Not a good solution, but better than nothing

Hey @haubada

thanks for the fine work!

My setup is a "Shelly Pro 3EM" (GitHub) and "Shelly 1pm Plus" (GitHub).

Everything seems to be working fine, the only problem is, that the "Shelly 1pm Plus" isn't displayed as PV-Inverter on the dashboard. Solar yield is displayed correctly, but the inverter is missing in the diagramm.

dashboard.png

Anyone got an idea?


EDIT: I think it has something to do with me not having a battery (-> no ESS).

I switch the Position to 1 (AC output) and now the inverter is displayed, like in the first screenshot of @vikt0rm


Thanks

the install.sh script should add a line to itself in /data/rc.local file like this example:

root@einstein:/data# cat rc.local

#!/bin/bash

/data/dbus-shelly-1pm-pvinverter/install.sh

So after reboot it will setup itself again, it even survives a cerbo version upgrade btw. but I don't have a Raspi so maybe the handling is slightly different there...

Do you mean

Yes, you can delete it. Perhaps it could help to edit the config.ini

The problem is a known bug. https://www.youtube.com/watch?v=kW8YTbdxZ9U

But I don't know how to fix it.

I do not need the log file. At the moment I am trying to find the max. value of SignOfLifeLog. At he moment it is 1440.

(60 x 24h = 1440)

So there would be only one event every 24h at the log file. If it works, I will try this with higher values.

Two changes in the code from Halmand are nessecary:

1. config.ini --> Add: Position with the needed value:

# Available Postions: 0 = AC, 1 = AC-Out 1, AC-Out 2
Position       = 1

2. dbus-shelly-1pm-pvinverter.py --> Change the line for Position to:

self._dbusservice.add_path('/Position', int(config['DEFAULT']['Position']))

The Position in my Remote Console and VRM Portal are now correct. I will see tomorrow if the values are correct too.

"current":1.264, 
"apower":281.0 ,


Python script searches for switch:0:

 if phase == pvinverter_phase and plusPmSupport == 'True':
             power = meter_data['switch:0']['apower']
             total = meter_data['switch:0']['aenergy']['total']
             voltage = meter_data['switch:0']['voltage']
             current = power / voltage


So two points:

1. Currently no github script uses the PlusPMMini and you have to adapt the script at certain points where the json file is read ( just change for example:

power = meter_data['switch:0']['apower']

to

power = meter_data['pm1:0']['apower']


2. I'm not sure what you mean with AC input. AC input is measured by the multiplus directly so no need to have a shelly for it. Or do you mean you want to measure what the grid is providing to your house on this phase? ( so you want a single phase grid meter?)

Ok, that figures. Thougt I had the correct device. I am not a good programer to be honest, but I have been looking at those lines to see if I could figure, but did not :-)

I will try to change the lines as proposed and see what happens. Or I just buy the 1PM.

Else, I do not have a multiplus (have Victron smartshunt, MPPT and inverter) so this power-meter is only measuring the power which are provided when the 3rd party charger (Cristec) is running.

Thanks.... that helped and the correct values showes up in the console. but not in the graphic and VRM.

Hi, i had bought shelly PM mini gen3 and tried to connect in venus os. but its not displaying the values. I tried this step

power = meter_data['switch:0']['apower']

to

power = meter_data['pm1:0']['apower']

and iam getting the values, but not in VRM.
