Heyhey @jblance,
with current version 0.16.01 I got problems with BATS command:
# mpp-solar -v
Solar Device Command Utility, version: 0.16.01
# mpp-solar -p /dev/hidraw0 -n 'BPVInverter2' -T 'BPVInverter2' -P PI17 -o screen -c BATS
Traceback (most recent call last):
File "/usr/local/bin/mpp-solar", line 8, in <module>
sys.exit(main())
^^^^^^
File "/usr/local/lib/python3.11/site-packages/mppsolar/__init__.py", line 424, in main
results = _device.run_command(command=_command)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/local/lib/python3.11/site-packages/mppsolar/devices/device.py", line 115, in run_command
decoded_response = self._protocol.decode(raw_response, command)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/local/lib/python3.11/site-packages/mppsolar/protocols/abstractprotocol.py", line 342, in decode
msgs[key] = [resp_format[2][int(result)], ""]
~~~~~~~~~~~~~~^^^^^^^^^^^^^
IndexError: list index out of range
Can you please check, if there is an issue with the BATS command (or am I stupid and broke my python)?
Thanks so much
Jakob

Can you post a debug output (add -D to command)

So the response is b'^D0941750,0560,0540,0000,060,0530,0420,0480,0480,0540,0,,,0,0480,000,0100,0175,010,020,020,080,0mr\r'
And the protocol definition (that I have / is using) has
which expects a 0 or 1
It works when the response has 000 response for this parameter
So the protocol I have is incorrect for this command on your inverter (also explains the 2 unknown responses)
I have no idea what 000 and 010 could signify or relate to. (parameter or value decode)
What is the model / brand etc of your inverter?
What does the --getDeviceId command return?
Any ideas?

Thanks for elaborating and quite strange @jblance :-). Inverter is made by MPP Solar and called "MPI 12KW WP" respective "MPI 15KW WP", in my case its a "MPI 15KW WP".
Maybe I´d ask MPP Solar for this fields function with MPI 12KW WP and MPI 15KW WP inverters?
Here comes the DeviceID
# mpp-solar -p /dev/hidraw0 -n 'BPVInverter2' -T 'BPVInverter2' -P PI17 -o screen --getDeviceId
Command: Get Device ID - Generate a device id
--------------------------------------------------------------------------------
Parameter Value Unit
deviceid 17:058

The WP versions of the 10/12/15k models run a slightly modified PI17.
The BATS command looks like that:
So the parameter seems to be "Battery under S0C".
I uploaded the latest PI17 protocol spec from 2022-09-22 here.
jblance commented
Ok, thanks for the protocol doc
What does "Battery under SOC" even mean. 000 and 010 seem to be the 2 values you have mentioned - any thoughts
Will look at adding a new protocol to cover this when i get a chance
jblance commented
added new protocol pi17m058 with a modified BATS in v 0.16.10 or late
JakobTewes commented
Works like a charm! Thanks so much @jblance!
