na just like the manual told you.
and yea, you have to use the ‘Console’ port! so you can use the rs485 port for something else.
using an wemos d1 mini was the problem. i dont know why but with a random esp32 board it works now.

Hi, thank for making this components. I managed to get it working but I notice that is not getting all the values. I have 2 batteries and is getting values from one battery only. Battery 1 and 2 are getting the same values and cell info for battery 2 only.

can you see the correct data when you use a serial connection to the master battery?
i rechecked my values, and they are 3 different barcodes. maybe you have done something wrong with the Master-Slave wire?
Hi,
trying since several days to read my 6 Pytes batteries and failing,
i do not get anything working…
any more detailed manual available ?
regards
Uwe
not yet sry … and tbh its not planed 
can you tell me what the problem is, i’m willing to help you out.
