    Hi @wojtbar, Hi, I have installed the latest firmware version on my TDT-6022 (L49) but now esphome gives me some wrong values (charging power, discharging power and power) and missing for example (state of charge and sampling voltage) could it be that the new firmware has changed the responses...

    Currently no, you can use an esp32 connected via serial to the BMS, but you cannot use BLE. Look a few posts earlier there are links to program us esp32. Bruno

    I've not update my BMS, just wait a little bit more (scary for my first firmware update), but I can share the firmware with anyone. Update at your own risk and only update if you know how to update it! 6022_15016S000_L_49_m.zip - is for 150AH TDT BMS 6022

    This is exactly what happens, the relay closing/opening, yes I had understood that the grid must be disconnected. But do you think there is a way to make it accept that? Could I ground the neutral so that I don't have two-phase anymore?

    Hi all, I have a deye SUN-8K-SG01LP1-EU (HMI: Ver 0000-C36D MAIN: Ver 0-6025-1724) What do you think? Is there a better update? Thanks
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    Hi, yes my big problem with the battery is that every day lost a few amp (SOC percentage). What do you mean with "150A BMS", that it charge / discharge maximum 150A? I've 300Ah battery pack. If you send me the last firmware I can send my email in private message. Thanks !!
  • Post in thread: Deye 8Kw - Port Gen to Axpert Inverter (Off-Grid)

    Hello, everyone, I have a solar system with deye 8kw single phase and its solar panels. I also have a separate old system with an Axpert inverter (off-grid) that I use in parallel only to charge the batteries, since the whole house system is connected on the load port of the deye. Now I would...

    Hi, where to check for firmware update of the TDT-6022? Thanks
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    Hello there, I've bought a GS battery 300ah, from China, there's no manual, no information etc etc. I've tried Meta App and it's connect and retrieve information, what about the password? I've tried some esphome(esp32) project like as seplos, jbk, bbd but the only one that receive a small...

    Hi everyone, how many time to update? I think I've brick the bms... Edit: I'ver checked (my fault) update mux. After this step, switched down the bms, reconnect and update without check this flag. I did it!! Now just to see if the SOC issue is resolved.

    Hello there, currently I have 6022_15016S000_L_16 Just to know if when I update, need to switch off all or not. Thanks PS I've wrote an email in October 26th to jack@tdtbms.com but never received an answer.

    The factory, told me that the last fw is "6022_15016S000_L_49_m". Anybody as tried these version? What does mean the "m" at the end? Thanks

    Hello there, no it’s just about esphome and the TDT’s BMS, I’d been looking for something like that for a long time.
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    Awesome.. about the rj11 (6 pin) of the BMS, what number of the connector can I use to uart-ttl ?
  • Post in thread: Deye 8Kw - Port Gen to Axpert Inverter (Off-Grid)

    The problem that even the deye when not connected to the grid has the neutral to ground. I wouldn't want it to create problems.
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    Do you think it works well with a TDT BMS 16S? Any advice to connect uart-to-ttl ? Thanks
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    Hello, everyone, after one year I changed inverter and connected the bms via CAN, the problem is that the inverter reads as BULK voltage 57.6V from the bms, how can I change the Bulk and Float voltages in the BMS? Any advice?
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    nothing to do.. I think something is wrong..
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    Hello, everyone, finally I can see what's going on in my battery pack, I noticed that the cells are not aligned in voltage, in fact I mounted a 1A daly balancer, I noticed though that in the BT application of the BMS (Bms META) there are some setting values that I don't understand, could someone...

    ? The switch?
  • Post in thread: Deye 8Kw - Port Gen to Axpert Inverter (Off-Grid)

    Sure Yes, 220V. Reversed? What do you mean? Thanks

    Esp32 ---> ttl<-->uart--------------------------------------------------------------------------->RS232
  • Post in thread: Deye 8Kw - Port Gen to Axpert Inverter (Off-Grid)

    Ah. ok it's AC but yes, the only thing is that has only two cables (L + N) without ground.
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    I've only one pack and yes, a lot of problem with the remaining capacity, every day it's downing 3 ampere more o less.
  • Post in thread: ❓ TDT-BMS Wanted Feedback/Experience

    I did! I've change a new esp32 and uart-to-ttl, I think during my last connection I've burn the ttl converter, otherwise done!!! Thank you so much. Just the last one.., there is no switch entity CHG MOS and DSGg MOS ? Thanks
