Hi

For my with DALY 200A and EASUN SVII 5kw inverter some commands work and some not work . For example for EASUN not work, but for DALY bms .... some work some not.
I try to send info in HomeAssistant with this command:
/usr/local/bin/mpp-solar -n Daly -p /dev/ttyUSB0 -b 9600 -P DALY -q 192.168.2.3 --mqttport 1883 --mqttuser ICC --mqttpass ICC123456 --mqtttopic DALY01 -o mqtt -c mosStatus
I put in a bash script all 6 command because I want to get info at 60sec (crontab)
Can you help me with thsi error:

Sorry thought I'd responded to this

can you run one of the failed commands with debug on (-D flag added to command)

Thank you John for your awesome work. I am successful in integrating a pair of MPP Solar LV6548 with home assistant. I also have a pair of DALY BMS and am seeing intermittent error on DALY checksum did not match. Here are the outputs with Debug enabled.

Please let me know if there is anything I can help test, including which part of code I may attempt to study or modify. I know something about Python so I can follow up on any pointers you may provide.

Thanks!

This is a working output got within a few seconds before the failure above. The failure is intermittent. I'd say about 1 out of 10 tries has checksum error.

I have also tried adjusting the Baud to 4800 and 115200 and continue to see intermittent error.

It could be that the code isnt waiting for long enough after sending the command and so sees an empty result

try updating to the latest version (if you are using pip to install, remove mpp-solar and install mppsolar)
