SimulatedBatteryPackPlugin not working? #66

I'm new to this, so please bear with me :)

I'd like to take a HV inverter (Huawei SUN2000 or Growatt SPH) for a spin with a simulated battery. I've installed the software on a Pi4, and get the following output every second:

I'd expect the 'fake' values to be reported under SOC and CellDiff etc.
Also, the | ---------------------------------> Thread 37 feels like a truncated error.
In the configurator, I put / as the BMS port, since the configurator required 'something'.

The resulting config.properties:

bms.pollInterval=1

bms.1.portLocator=/

I have little Java experience, so no idea how to investigate further. Please advise how to proceed. Thanks!

@krekr the plugins are now working. I fixed a bug yesterday. Please get the latest Configurator app and do a Clean install.

@krekr I implemented the plugins now. There were some errors initializing the plugins.
The BMS will log no data, but you will see the inverter binding sends CAN message with values 😄

Wow I feel like I'm getting support for a paid software package, haha. Thanks so much. I will try this soon.

Please note I'm running the configurator on Windows and haven't attached a CAN Hat to the RPi yet. It looks like it's trying to read two BMS'es?
I will try to get the CAN communication up and see what happens!

Yes, that is what I mentioned before, that the BMS will still show no data. But the CAN message going out to the inverter will have the simulated battery property values encoded.
Those 2 BMSes I still have to fix on the NONE BMS binding, but that has no influence on the behaviour 😄

Hi so SPH10000
config >

bms.1.type=NONE

inverter.type=GROWATT_CAN
inverter.portLocator=/dev/ttyUSB0
inverter.baudrate=500000
inverter.sendInterval=1

But dummy battery works :)

I see only RX activity on CANUSB

romanbetwo Oct 9, 2024

okay, wait a second, I should be able to dump messages from using ./canusb -t -d /dev/ttyUSB0 -s 500000 -t as I see RX activity

but this is not happening .

pi@raspberrypi:~/USB-CAN-A $ ./canusb -t -d /dev/ttyUSB0 -s 500000 -t

Ok great! So the errors are fixed.

But it can't find a CAN device under /dev/ttyUSB1:

2024-10-10 09:45:27.486 | ERROR | Thread-3 | toinverter.core.Port:116 | Opening port /dev/ttyUSB1 FAILED!
tel.schich.javacan.platform.linux.LinuxNativeOperationException: Failed to resolve the interface: /dev/ttyUSB1 - errorNumber=19, errorMessage='No such device'

Please make sure its initialized properly.

@krekr the plugins are now working. I fixed a bug yesterday. Please get the latest Configurator app and do a Clean install.
