Pylontech Battery monitor

I have successfully built the Pylontech Battery Monitor interface,
I have a stack of 4 Pylontech us2000 batteries.
Can anyone tell me the correct syntax of the datalist command, Show recorded data.

datalist [event/history][item/bat][batnun][volt/curr/temp/coul][item]

I can query the master battery where the console cable is connected, but not batteries 2, 3 and 4. I can’t get any results, just a syntax error!

Thank you
