I have installed your fork but is the same. No data “PV_in_wats”:

I’ve just been debugging this same issue, its because the code is hardcoded to calculate pv power from SCC Voltage which is always being returned as 0.

I modded the code to read it from the QPIGS command instead but haven’t yet been able to make it work since it doesn’t seem to want to use the locally built version on my pi, preferring to use the stock version from github…

wax911 · July 11, 2022, 3:50pm

Hey so sorry for the super late reply, I’ve been tied down for the last few months. Have you managed to get your issue sorted?

jmwick · July 17, 2022, 3:15am

Is there a running list of confirmed inverter models that this is working with? If not, can everyone post their model here? Specifically, I’m wondering if MPP-Solar LV6548 works and/or EG4 6500EX.

quintinsleeking · July 18, 2022, 7:43am

Hi Where do i find the file to change these values?

Kind Regards
Quintin

Hi guys,
I finnaly set up my homeassiastace with my solar inverterMKS5K MKS5K. To do it i have use old laptop running on Debian witch installed Home Assistant Supervised. to comunicate with inverter i have used mpp-solar soft from mpp-solar. Mpp-solar wos the easyest and the fastest way to download data from inverter via usb to homeassistance.

with this setup i dont have to bother about QPIGS values and ather, and its working.

my mpp-solar config looks like this:

/usr/bin/watch -n 1 mpp-solar -C > /dev/null 2>&1 &
exec bash

i hope it help someone

This is so simple and straightforward that it hurts, after hours and hours trying to make the above program talk to hassio.
Thank You

The catalin fork has been working well for me and has been great watching and changing the inverter settings without having to crawl under where the inverter lives.

Noticed that I can see how much solar is coming in, how much AC load is going out… but don’t see an entity that shows how much the inverter is charging my battery/supplying to my DC system.

It’s on a PIP1012LV-MS. Is DC output/charging something it measures? Or how much is from solar and how much is from the grid? I’d love that data.

*I see “battery_charge_current” but it shows 0 despite currently charging at 15amps or so according to my BMS.

Hi, I’m trying to install this directly in to Raspberry PI Home Assistant image (Home Assistant OS) but getting error related to read only when trying to start MQTT docker Any advice for continue from this? Do I need modify files?

SuperMaximus · August 20, 2022, 6:47am

How should I configure an inverter.conf if I need to use this container for two inverters?
Each unit connected to a separate port of Raspberry Pi.
Now my config is:

# Basic configuration options for the actual inverter polling process...

# The device to read from...
# Use: /dev/ttyS0 if you have a serial device,
#      /dev/ttyUSB0 if a USB<>Serial,
#      /dev/hidraw0 if you're connecting via the USB port on the inverter.

device=/dev/hidraw0

# How many times per hour is the program going to run...
# This is used to calculate the PV & Load Watt Hours between runs...
# If unsure, leave as default - it will run every minute...

# (120 = every 30 seconds)...
run_interval=120

# This allows you to modify the amperage in case the inverter is giving an incorrect
# reading compared to measurement tools.  Normally this will remain '1'
amperage_factor=1.0

# This allows you to modify the wattage in case the inverter is giving an incorrect
# reading compared to measurement tools.  Normally this will remain '1'
watt_factor=1.01


# The following settings allow you to modify runtime buffers.
# N.B. These values may not be applicable to all inverter types, as such you will 
# need to run docker exec -it voltronic-mqtt bash -c '/opt/inverter-cli/bin/inverter_poller -d -1'
# or simply inverter_poller -d -1 to check for warnings or errors
# mentioned in https://github.com/ned-kelly/docker-voltronic-homeassistant/issues/5

# This allows you to modify the buffersize for the qpiri command
qpiri=108

# This allows you to modify the buffersize for the qpiws command
qpiws=45

# This allows you to modify the buffersize for the qmod command
qmod=5

# This allows you to modify the buffersize for the qpigs command
qpigs=110

I reinstalled your fork
strangely, now PBDV27.3 works, any other value not. Probably because 27.3 was my previous and current setting.
Then I tried different values:
PBDV27.3
PBDV27.2
PBDV27.1
PBDV27
the reply for PBDV27V is:

I checked the hex bytes sent for all values:

50 42 44 56 32 37 2e 32 70 21 0d
50 42 44 56 32 37 2e 31 40 42 0d
50 42 44 56 32 37 48 3f 0d

which in ascii are:
PBDV27.3`
PBDV27.2p!
PBDV27.1@B
PBDV27H?

It’s correct? was expecting the same closing value.

catalinbordan · September 12, 2022, 12:02pm

It should work, but as I can see in your reply does not.
Am sorry but I do not have any ideas. I am just a guy to take all the ideas from others forks and combined in my fork… You could try to search in forks to see who did the this changes for sending commands in multiple messages and try to contact them.

Snubbeke · September 19, 2022, 2:09pm

In my case all voltronic config entities are present in HA (latest version) and in the log Viewer I can see that sensors are updated but they remain not updated:

With /opt/inverter-cli/bin/inverter_poller -d -1 I get the following:

I already changed settings in inverter.config like:
voltronic-conf

And I also applied:
voltronic-putty

Bought a cable connected:

Any tips to get the data into HA?

Any tips?

virtaz · September 22, 2022, 12:08pm

Howdy all!

1st of all, BIG thanks to @ned-kelly for this project!

I have now the container up and running on my Pi4 and I’m getting the correct readings from the inverter ( Effekta AX-M 5000)

But I have few questions:
-Should the inverter entities be under a Device? atm I’m having them all indentified as sensors with no device or area
and also they are missing an unique id, so using them is kinda tricky and you can’t give names to entities or edit them.

At some point on my installation process I had one device under the MQTT integration, and it listed all the entities, with their names correctly visible.

I guess I got something wrong with my settings but I can’t figure out what could it be…

Anyone got an idea how to get all inverter entities under the inverter device ?
Any help is much appreciated!

virtaz · September 22, 2022, 12:09pm

Snubbeke · September 22, 2022, 3:07pm

I have a similar problem that entities show up in HA and get updated but value is not updated in the message and it states "ignoring unchanged update ":

But where is the value in the message?

Any idea?

virtaz · September 22, 2022, 3:54pm

have you tried MQTT explorer?

it shows the values, if they are working ok.
