We are now at the same point. I dont get values with my splitter. Either the esp32 or battery bms doesn't come through. But my own crimped cable works fine. Even though I have checked the spittler with a multi tool and the pinouts are exactly straight end to end. I guess one of the "unused" battery pins are conflicting with the rs458 or I must double check my crimps. Its allso possible that there is interference with a unshielded cable. 
As for slipxs flow card I think it needs his yaml code as it will make things easier but not nessary. His yaml file can be found in the same folder as the flow card. 
Im also getting some of the double sunsynk names, for now I just renamed the sensors in the code of the flow chart. I think Im going to redo my setup from scratch to make sure there is no unused entity sensors as I deleted some of them with the double sunsynk name and it didn't make a difference. 
Lastly his code to set up the all in card for the charts are not working. Scoobs has a video on this to setup the graphs individually each one on its own card but you will have to put each sensor in manually. And organize the cards yourself. 
 

Hi thanks for the advice @XAB@XAB it turned out to be exactly this. All the guides say top left port and it even says RS458. I came accros that 2 in 1 port and thought to myself there is no ways as mine is has a dedicated RS458 and its on the top left. Anyway when reading @fStofs post I thought just maybe and the plugged out battery cable and it just worked. sorry I couldn't reply been working. Made myself a 2 in one cable for the time being and have ordered one of those rj45 splitters. Just need to get the rest of the dashboards graphs working as some of the sensors have esphome in them.

Hi Guys, Im hoping someone can help
Im new here, but I have been following the forum and Sc00bs videos, I am brand new to home assistant and esp32/RASPI, and can not code. however I generally understand the code here and there due to Excel macros and so on. I have also been flashing custom roms on phones and GPS's from young.
I have the following setup, 5kw sunsynk inverter with 5.5kw Hubble am2 battery connected with can bus and only 4x 550w panels for now.
My home assistant OS is a fresh install running on a HP prodesk i5, ssd and 16gb ram in my room with my router and switch. I have a cat5e cable running from my router 25m to another router that is setup as a dedicated AP right next to the inverter, so I get a stable 50mb on wifi.
So far I have managed to wire the ESP32 & RS485 up as in the picture's 1&7 to B an 2&7 to A.
ESP32 is wired up like below
Flow control to pin 20 GPIO4 - I saw in slipx newest code that his flow control is GPI016, I tried like this but then changed the code to GPIO4 - I was too scared to put the flow control on GPIO16 as this is RXO according to the diagram, and did not want the magic smoke to come out
When I tried sjlouw code on page 3 I had used RXO-GPIO16 & TXO-GPIO17 as his code says, I got no response received - removed from send queue
now tried SlipX06 and moved the pins to 28 GPIO1 - TXO & 27 GPIO3 RXO - I get the same result of no response received - removed from send queue as before but with added yellow text about duplicates [W][modbus_controller:113]: Duplicate modbus command found: type=0x3 address=70 count=10
My first cable was a factory made T-568B(starting with white/Orange)
I then made a cat5e shielded cable also T-568B but my RS485 does not have ground unless soldered.
I have tried this code at the beginning
esp32:   board: esp32dev   framework:     type: arduino     version: 2.0.6 Because I don't have a multimeter and soldering iron at home, before install I took my RS485 to work and I measured the volts on the RS485 and got 0.5v and desoldered it straight away as I saw above most people with Sunsynk had to do so, and measured again to get 4.5v across A and B, I have checked my continuity on all my wiring to check for bad jumper wires.
and lasly my Modbus SN is set to 01, the only thing I can think of is that my firmware is out of date. but from what I have read people get more issues the newer the firmware. Please see attached Pictures
Any help will be much appreciated
