rjpearce / sofar2mqtt-python Goto Github PK

Hello,

I am getting an error since today.
I got a state "Emergency Error" on the Sofar state and I was not able to write anything anymore. Seems there was temporary a low frequency statement but the inverter is working fine. But since then I was not able to change the state anymore on the Sofar and data froze.

Restarted the container on my Synology and the container doesnt want to restart anymore with an error.
In case, I restarter my inverter but didnt solved the issue.

Attached the logs I have. I was maybe expecting a communication issue but seems to be ok, all cabling and usb stick is properly plugged and detected by my synology with drivers and co.

When it boots, I have those mqtt poping in the channel :
Topic: sofar/desired_powerQoS: 0
0
Topic: sofar/pv_total_powerQoS: 0
0
Topic: sofar/gridQoS: 0
0

Then the error occur as below:
rpearce-sofar2mqtt-python-1.csv

Thank you for your support.

Battery status reported as 527% for a short period which is clearly insane.

Ignore values higher than 100%

Im using your library in a docker environment for testing, mqtt broker serial connection everything is up and running, status messages come back for the me3000sp but my question is this, i would like to use the following in compliment with your code and are trying to find the most minimalistic approach of using it without modifying the original code too much:
{
"registers":[
{
"name":"standby_mode",
"function": "setmode",
"register":"0x100",
"write": true
},
{
"name":"discharge_mode",
"function": "setmode",
"register":"0x101",
"write": true
},
{
"name":"charge_mode",
"function": "setmode",
"register":"0x102",
"write": true
},
{
"name":"auto_mode",
"function": "setmode",
"register":"0x103",
"write": true
}
]
}

Can you tell me where in the code to best put it and how i should call the methods topic string wise as to not conflict with other methods in your original code?

Ive pondered in putting it in the original sofar-me-3000.json but im unsure how to do this in a safe manner (dont want the code to be called along with the status messages by accident continuously for example)

To be more exact once my message has safely arrived in your code for example in onmessage and it doesnt conflict with other code i can safely stitch on from that if you could get me to that point. (I could do it myself as well but i consider that generally more unsafe than asking you directly as the conflicts could put unnecessary stress on the inverter and possibly wear it out faster)

Using the example from the setup guide and running
sudo docker run --name sofar2mqtt -e MQTT_HOST=x.x.x.x -e MQTT_PORT=1883 -e USERNAME=mqtt_user -e PASSWORD=xxxxxx -e CONFIG_FILE=sofar-hyd-ep.json -e TTY_DEVICE=/dev/ttyUSB0 --device=/dev/ttyUSB0 rpearce/sofar2mqtt-python:latest

I get the exec error
exec /usr/local/bin/python: exec format error

This is a fresh install of ubuntu on a RPI4 with official docker setup. Nothing else.

Thanks

Using a slider with desired power and step 50 makes it very hard to pick 0, especially on a mobile device.

hi,

using this command line : python3 sofar2mqtt-v2.py --broker 192.168.10.231 --config-file sofar-hyd-ep.json --device /dev/ttyUSB0 --retry 5 --daemon

i get the following result :

as a matter of fact, there is nothing created in mqtt.

could you guide me on a solution ?

As grid power is a substarct of load_power - active_power it gives unwated results when active_power is very low or 0 .
active_power is reported sometimes less than zero which give a higher grid power .
when is is 0 it report a negative value instead of positive for grid power .
