I will try another talk to him via discussion! It's weird that a friend of mine has done the reading successfully over hardware serial on esp8266 D1 promini but not on esphome. He did not use SoftwareSerial (of course esp8266 has problem with SoftwareSerial). Esp32-esphome use softwareserial...

I talked to Syssi already on that and he did not response yet! Problem is on the BMS side, not him! I did a fork from his component and tested with uart reading command but nothing worked at all. JK seems to have problem with 11.XW version (for firmware later than 11.36 and 11.42 - I have those...

Many thanks @Sleeper85 for your information. I don't have 11.XA version (I thought XA and XW might be the same) so I am not quite sure, mine is 11.XW (11.42) and I tried both using Arduino, esp32, none of them worked! I revise also the reading command "4E 57 00 13 00 00 00...

Me too, I have several esp32-S2lolin in remote internet address but ota and even api (initial version now I moved to MQTT ) and all working fine!

I run several esp32s2lolin and have no problem with OTA until now: OTA: - port: 8266 Instead of using dhcp, I set manual Ip or bind ip to mac at router so the esp32 will always have fix address. I used 'use_address: ip_address_of_mydevice >> all working fine. I run tens of esp32lolin in ten...

No 11.43 will not response to request data command as I have mentioned (my version 11.36, 11.42 does not work on wired connection anymore, the "4E:57:00:13:00:00:00:00:06:02:00:00:00:00:00:00:68:00:00:01:28" command does not work! I have not upgraded to V15 as guided by JK-BMS guy as I have not...

You can check here, he made details guidance and resource included then! https://off-grid-garage.com/battery-management-systems-bms/ The guy from JK-BMS (engineer informed me that it needs to update to V15 but he provided no further information). I have tested this yet. Better using...

So you are using one ESP32 for each connection or trying to combine into 1? In case you are using 1: you need to be sure that the wire connection is made to a JK with firmware version is earlier than 11.28. Later than this, you will have to upgrade firmware to Version 15 (as told by JK engineer).

Hi, This is not for OCV or totally rest calibration. It is current calibration for JK to measure correctly! Both current and voltage are needed for Coulomb counting to work effectively. What I am focusing on is how to make JK work most effectively! Best!

I use multimeter to do the work when charging at current above 2A on both voltage and current. Then set the calibrated value once only. The rest is to keep the charge prolonged to bring the battery voltage as high as 3.45*16 and as low as 3.2*16 while maintaining delta voltage be lower than...

1.: Thanks @Sleeper85, Actually, I used this approach for both ends but using 98 and the minimum SOC (not 2%) to reflect the SOC cut-off level needed for the Inverter to stop charging (.i.e Cut-off/ On-grid EOD set at 20% but JK SOC is lower when minimum cell voltage is still 3.1V or more, the...

I understood your points: Lux has problem working with Voltage when setting battery as lion. It does not behave as configured such as to discharge in defined time (if setting charge base on time and SOC or Voltage with time range of 7AM-5PM, AC charge current to 0). To activate the discharge...

Hi, I think we should not debate on SOC issue any more, It can be solved already: + If JK SOC reported 100% at 3.35 or somewhat too low (less than 3.4 while charging) >> it need to keep charging, it can still absorb: in my case, I report to Inverter 98% (Sleeper85 use 99%) as Inverter sometime...

It was a metaphor to imply the simplicity for users when they apply this method to allow Lux to manage the charging process without worrying once correct limits on voltages are configured on the inverter. I did some changes on the code for bringing voltage control to manipulate...

Thanks to @silverstone and @chaosnature! I just tried a test first and then moving on shaping the code back to the main version that Sleeper85 and Mr. Pablo is working! The initial result shown that it can work as expected for at least Luxpower/Deye Inverters (what I have for testing and they...
