Any chance you can download the logs and attach them here?Here’s what I fetched
I have a repeater with the same ssid as the router and the esp has connected to the router instead of the repeater. I have specified the bssid instead the ssid and it works fineAny chance you can download the logs and attach them here?
What is the value of "Uptime Human Readable" sensor in Home Assistant or in the logs?
It looks like the ESP disconnected from WiFi, what is its WiFi signal like?
Try to move it closer to the access point or try changing the channel on the access point
thanks for doing this. What happens when one of the slaves or master stops accepting charge such as from a high cell voltage?Multi BMS Alpha code now released.
Update: Alpha V2.16 more info here
I completed and implement the initial design, the data is now combined from the slaves as per the design.
I have made many improvements and made the code more robust, see the above link for more info.
Future plans include adding Multi BMS support for JBD/Overkill so you can mix and match BMS in the one larger pack.
As per the design:thanks for doing this. What happens when one of the slaves or master stops accepting charge such as from a high cell voltage?
It's on my radar but not something that has many requests or any Patreon supporters, so I haven't progressed with it.Hi! Thanks for all the great work! Do you have plans to support RS485 pylontech protocol with JK BMS for supported inverters in the future?
Thanks for the reply. I really hope one day you will be able to make/release it as all of the voltronic inverters don’t support pylontech over CAN.It's on my radar but not something that has many requests or any Patreon supporters, so I haven't progressed with it.
Unfortunately there is a small minority of inverters that don't support CAN, poor design by the manufacturer if you ask me, as most of the batteries on the market use CAN.Thanks for the reply. I really hope one day you will be able to make/release it as all of the voltronic inverters don’t support pylontech over CAN.
Some support by the community would really help this project come to life one day.
That’s true unfortunately for us having these kind of inverters. I am hoping to find a solution in the futureUnfortunately there is a small minority of inverters that don't support CAN, poor design by the manufacturer if you ask me, as most of the batteries on the market use CAN.
Hi and thanks for the great project you done.
A quick question. Can I set up a kvaser can dongle to send and emulate the inverters can msg to the esp32 to see if everything works and so it doesn reboot?
What are the canmsg that needs to be sent and how often?
Hello, I have an inverter with pylon rs485 protocol, and I would like to test it.Starting to put some thought into support for Pylon RS485 protocol, does anyone have their inverter connected via RS485 and can log and send me some data?
Have progressed with creating code that produces the responses as per the Protocol, let me know if you have a data from the inverter.
eg what the inverter is asking it should be something like one of these:
rx_fixed {0x7E,0x32,0x30,0x30,0x32,0x34,0x36,0x34,0x32,0x45,0x30,0x30,0x32,0x30,0x32,0x46,0x44,0x33,0x33,0x0D}
rx_fixed_FF {0x7E,0x32,0x30,0x30,0x32,0x34,0x36,0x34,0x32,0x45,0x30,0x30,0x32,0x46,0x46,0x46,0x44,0x30,0x39,0x0D}
We are doing some testing over at https://github.com/Uksa007/esphome-jk-bms-can/discussions/27Hello, I have an inverter with pylon rs485 protocol, and I would like to test it.
I can log inverter requests, so I can send you next days

No, BLE is not supported.Hi,
Can I connect BMS via BLE and make CAN BUS connect to inverter, because I cant open case to connect UART
Thanks! I mean battery's case. Opening it will lost warrantyNo, BLE is not supported.
The connector is on the bottom of the JK-BMS, you don’t need to open the case.
My interface kit has all the needed hardware and cable for the BMS.
The number of cycles are not sent to the inverter from my code, so I'm thinking this must be something that the inverter is calculating, is there anything in inverter manual that might suggest how it calculates it?I just have a problem for the number of battery cycles. The value transmitted to the inverter corresponds to the current value.
What modification can I make to correct the information?
