Big Thanks to Miro! This is AWESOME! A little information for general clarification: The codes do NOT work (at least on the new Inverter BMS models, I only have those) to bypass forgotten or incorrectly set settings passwords! These are only for the firmware flash! My PB2A16S20P made a complete mess when setting up for the first time and setting my password and I was completely locked out! ESPHOME in conjunction with an ESP32 and "esphome-jk-bms" helped here. From there, flash the "esp32-ble-example.yaml" (with adjustments to your own BMS) to the ESP. The password set in the BMS is then displayed in the LOG file! The BMS or the software had saved my set password completely reversed... For whatever reason! for example, "123456" became "214365"!
Well I've always wanted to go, but didn't have a place to stay. You think he would let us camp out in his back yard? I've got a sleeping bag and even a tent. Wonder if I can write it off on my tax as a business expense. Technically I have installed solar on RVs for business. I can leave the little woman and kids here. Lol.

Miro is the BOMB! As others have said, My JK B2A20S20P BMS continues to "forget" my password and I had to contact JK everytime I needed to pair with my phone. I would love to hear how to fix the password issue permanently but this is the next best thing.
It was prompting me whenever I tried to connect. I discovered it was because I hadn't reset the password. Since resetting the password it works fine😞 sorry for wasting your time, but it's good to mention, after using the code generator, reset the password 🙄 seems obvious now😊

Aloha from Hawaii! I am living off the grid at my farm and have a very reliable PV system consisting of 12 250W 30v panels, a PowMr 5000W hybrid controller, and 2 24v x 100Ah LiFePO4, batteries hooked up in series to give the 48v needed for the PowMr. It is working without any problems except when there is 2 days of bad weather with little or no direct sunlight which runs down the batteries. I want to add an extra 100Ah of 48v battery so that I can weather the 2 days when that arises.. My question is since my original batteries are nearly 3 years old, is there going to be any issues with incorporating new batteries to my system. I really enjoy your channel for your more in depth approach to living with an off grid solar system.
No problem at all. As long as they are all the same chemistry (LiFePO4), the same cell count (8s) and have their own BMS, you can parallel as many as you like, even with different capacities. I've shown this here and in many other videos: th-cam.com/video/bhCSccNsQOw/w-d-xo.html

@@mirofromdiro I just had the problem that the password 123456 didn't work with the new BMS.

The LCD V2.0 protocol is added to the protocol library, which supports charging and discharging through the touch screen. 3. The Victor protocol allows the vendor name to be changed by writing the user's private data. 4. Fix a bug, parameters (RFV Time) Storage failure.

Hi man what firnware is the one has no errors at all
I have a JK dp2a16s15p BMS connected to my victron.
but when it goes into float mode there isn't a fixed voltage applied but instead the Battery is charged and discharged all the time with something between 5 to 30 amp every 10 to 20 secs. The discharge is always 0.4 amps lower then charge.
The Soc is also really strange as it jumps from 50% to 100% within 30 minutes of charging in the morning, which can't be true.

Breaking News, but where are Andy 2, 3 and 4? 😢
They are all on leave in NZ atm... thankfully🤣
Hi Andy good thing that code is fine Listen I have to the JK A battery must be connected to update it or not because I have connected it to a stabilized power supply I have made the connection to the pc but I can not update it even by entering the brute Force code I have not connected loads or the temperature sensor or I am connected the cables for the display and then the negative and positive of the power supply with the its cable to the positive but Nada is not able to update So I will have to connect it to a battery that I have at home from 16 s280 amp
Power supply is fine, no need for balance cables or connecting it to a battery. It just needs to run for the update.
Maybe you have the wrong fw for your BMS?
@@OffGridGarageAustraliahi andy only ok 😊 the problem cable ,The problem was the RJ45 cable that was broken somewhere 😂I changed the cable and everything worked fine even with the code application ❤❤❤❤❤ 🍻🍻🍺
NOT WOrk for me , i have a 11number i have a code but not work :(
@Miro,
Great hacking!
Does the code generator still works?
yes
Hello everyone. Hot news. New firmware for hardware v15 is published. Not tested yet.
-V15.11 Upgrade logs
1. DRY Trigger source added "12 - Remote Control "option
2. The LCD V2.0 protocol is added to the protocol library, which supports charging and discharging through the touch screen.
3. The Victor protocol allows the vendor name to be changed by writing the user's private data.
4. Fix a bug, parameters (RFV Time) Storage failure.
What the heck are you going to do when someone comes out with the "perfect" BMS?
As long as they come from China... it will never happen🤣
Toe code looks similar to the growatt codes

Hi Andi. Is it right that a Tesla has over 30% charging losses. Maybe you can check that. If it's right that would be a mess.
I made many tests in this regard. It's all here: youtube.com/@unpluggedEV
Das ist der Miaumann der Katze
try to connect bms P- bank 2 and bms P- bank 3 to B- bank 1 , no more Peter boards 😎
Hallo Andi. Nochmal auf deutsch. Ladeverluste eines Tesla über 30% ? Wäre Interressant das zu überprüfen. Liebe Grüsse nach Down under aus Austria.
Hab ich alles gemacht auf meinem EV Kanal: youtube.com/@unpluggedEV
LOL … wessen idee? Also doch ein datum😂
Javascript, not PHP :)
Was probably rewritten to javascript to host it on static GitHub page.
@@davidb.5544 yes, most likely. I just thought it interesting to mention. Easy to host anywhere if someone wants to, including Andy.
And as a result can be uploaded to Andy’s website no problem.
Exactly! I'll upload the PHP and python code to my GitHub if someone is interested.
@omdiro I don't even have a JK-BMS, but this is a massive win, thank you! When you BUY such a device, you should OWN it. Not be dependant on the manufacturer to allow you to do with it as you see fit. Ridiculous.
Najo, siebzehnterisanedschlecht....
