hi got 2 PIP 4048 MSD they come with usb only connection connected via us as /dev/usb/hiddev0+1 please help me get it fixed this is what i got on my pi and the same on my laptop

maybe lsusb or dmesg helps while i think the device is maybe wrong

The code uses a simple serial connection approach. I dont think that the normal USB connection works in this way. Likely it needs something like https://github.com/pyusb/pyusb/blob/master/docs/tutorial.rst (from https://stackoverflow.com/questions/12542799/communication-with-the-usb-device-in-python)

I think my old PIPs have direct USB as well as the serial - when I get a chance I'll have a look and see if I can figure out how to make this work.

ok thx for the answer. I will close the issue. if u need some infos about my MSD just let me know (and it's also 3-4years old now i think) will try with usb to serial adapters now just thougth this should work without the adapters while there is a build in adapter like shown in lsusb

jblance commented 5 years ago

have checked in some real rough code that seems to work (sometimes)... [stolen mostly from cabellop5] still needs more error checking especially for failure to connect to device

jblance commented 5 years ago

I've improved the code a bit - it now (should) deal with connection errors Debuging should now work....

Give it a try and let me know how it works for you (I've done some tests using direct USB and /dev/hidraw0)

hi sorry i wanted to answer earlier but.... at the moment i run emoncms and solpiplog from njfaria and iḿ pretty happy with that for now had no chance to test your new code untill now just tell me if i should test it quick for feedback about my inverters
