Implent Battery Packs AC200Max?

[Hankersern]

Hi There,

thank you so much for publishing this project. Its my first time I flashed an ESP32 myself, and now I am really happy working with it.

One Thing I am missing: I cannot find any info about the Battery Packs attached to my AC200Max. In https://github.com/warhammerkid/bluetti_mqtt/pull/45/commits/c4b87323918920e6ea3eec24d81afd30d8d78be2 it looks to me like they added them.

Could you implent this? Would be great!

Hey @mariolukas

dont want to bother you! Do you have plans to implent this?

As I have no idea how github really works, could I ask some IT-Guy/Girl to implent this / contribute? 2 Kisten Jever are waiting for the person who does it ;-)

Thanks & best regards Timm

What Battery information do you need? There was a PR in February where information was extended:

https://github.com/mariolukas/Bluetti_ESP32_Bridge/pull/51/commits/69f349c0b20f46fbb7ed819f2d32705a5d372d06

all possible values form the bluetti_mqtt Repo you mentioned are included: https://github.com/warhammerkid/bluetti_mqtt/blob/main/bluetti_mqtt/core/devices/ac200m.py

I need the Status of the extension packs (% of Load) On the display of the ac200max its available but I dont have it in the mqtt messages.

The values of the individual battery packs can be queried by a command. In the original file, this is queried at this point:

Controls

    self.struct.add_uint_field('pack_num', 3006)

Hi,

thanks a lot for your help. Sadly I have no idea where to use that code. Can you give me a hint?

[dbergens]

In the original code from warhammerkid you can find the following command section:

Controls

    self.struct.add_uint_field('pack_num', 3006)
    self.struct.add_bool_field('ac_output_on', 3007)
    self.struct.add_bool_field('dc_output_on', 3008)
    # 3031-3033 is the current device time & date without a timezone
    self.struct.add_bool_field('power_off', 3060)
    self.struct.add_enum_field('auto_sleep_mode', 3061, AutoSleepMode)

To get the individual battery packs (up to 3 maximum) displayed, it is obviously necessary to send a command to the central unit (1st battery pack). Then the battery pack information is displayed according to the selection.

Using the original from warhammerkid and installing it on a Raspberry Pi, I was able to successfully test this on an AC300.

using the ESP code here, the AC200M config file is containing this part:

//Page 0x00 Battery Details //constant value, number off possible battery packs, 3 on AC200M, one internal and two external {PACK_NUM_MAX, 0x00, 0x5B, 1, 0, 0, UINT_FIELD },

Does I have to change the size = 1 to then 2 for internal + one external battery only, or do I also have to create an additional table for external batteries. e.g. definition in enum field_names does not contain external batteries.

So it not simple config of 1,2,3, but a extension of todays code required or?
