Pfew, thats it… it’s back…

Any idea where to get the correct string in the app then?

Maybe here?

Did you get this in ESPhome or nRF?

That string in the example is in ESPHome.
Is the string you get a notification or is it if you press one of the arrows, in my case this string comes from one of the notify characteristics.

I just got back home, i will have a quick look what happens with the string you provided, but i noticed its totally different format in nRF and Esphome, with only the one in esphome giving right results. (nRF is hex format, and esphome uft-8 i think)

What you might try, find all the notify characteristics in nRF and make a sensor out of all of them with this (this is all notify characteristics i see in your screenshots):

text_sensor:
  - platform: ble_client
    ble_client_id: my_ble_client
    name: "BLE Service dump 1"
    service_uuid: 'f000ffc0-0451-4000-b000-000000000000'
    characteristic_uuid: 'f000ffc1-0451-4000-b000-000000000000'
    notify: true
  - platform: ble_client
    ble_client_id: my_ble_client
    name: "BLE Service dump 2"
    service_uuid: 'f000ffc0-0451-4000-b000-000000000000'
    characteristic_uuid: 'f000ffc2-0451-4000-b000-000000000000'
    notify: true
  - platform: ble_client
    ble_client_id: my_ble_client
    name: "BLE Service dump 3"
    service_uuid: 'FFE0'
    characteristic_uuid: 'FFE4'
    notify: true

so without the internal part unlike in my full example, so you can see it in home assistant.

I am not sure if your battery has the button on it with lights for the current state of charge, when i connect to my battery and have the notify services enabled pressing the button triggers the message on the notify service as well.

Where do I press what? The button in esphome?

devilmastah · June 20, 2024, 4:26pm

No i mean in the nRF app, so did you get this value when pressing on one of the arrows, or was it a notify update after subscribing to it in the nRF app, i think to subscribe to a notify service its the 3 arrows down button.

But i would try what i posted in my earlyer post with the 3 text_sensors.

sender · June 20, 2024, 4:41pm

Will do this.

But what arrows do you mean? On the battery? I dont have that… only a “power” button, which is not a power button

So only the "BLE Service dump 3" gives an output… and a lot! - so much it keeps crashing the connection with HA. Can only get logging from esp directly.

Not sure if it helps, but these are only the values of "BLE Service dump 3" it gives:

@sender That looks quite promising, i put one of the outputs in my python script:

Decoded values:
voltage: 13345
current: 0
capacity: 30000
cycles: 1
soc: 86
temperature: 2917
status: 0
afe_status: 12
transformed:
  temperature_celsius: 18.6
  voltage_display: 13.345
  current_display: 0.0
  cycles_display: 1

so i think the value you are looking for is the BLE service dump 3
I would remove the other two in that case, and set it like this:

  - platform: ble_client
    ble_client_id: my_ble_client
    name: "BLE Service dump 3"
    service_uuid: 'FFE0'
    characteristic_uuid: 'FFE4'
    notify: true
    internal: true

So the complete script would look like this i think in your case, note the last comment in it at the bottom, possibly you dont need the two lower things. Also put in the mac adres again :

esp32_ble_tracker:
  scan_parameters: 
    duration: 90s

 

# Define the BLE client
ble_client:
  - mac_address: "" # Replace with the MAC address of your BLE device
    id: my_ble_client
    on_connect:
      then:
        - lambda: |-
            id(ble_connected) = true;
            id(ble_state) = "connected";
    on_disconnect:
      then:
        - lambda: |-
            id(ble_connected) = false;
            id(ble_state) = "reconnecting";
        - script.execute: reconnect_ble

## To find the mac adress, most easy way is to enable the part down below saying:
##   - platform: ble_scanner
##     name: "BLE Devices Scanner"     
## This will show all found BLE devices in the area with their mac adres and name if they have one in the esphome log.
## In case of a X210 battery the macs start consistently with: DC:0D:30:

And I commented out:

Because I thought that might fill the logs…

But still no readings. Other errors:

I really hope this will start working

ha interesting, i thought the ‘’ around the data you provided were some weird artifact of copy pasting or the console.

(so i removed all of them leaving me with for example this: ^2134000000000000307500000105600650B00800C94050D0A0D0C0D060D000000000000000000000000000000000000000000000000336)

Looks like its in the actual data.

So i think only thing needed is to remove those pesky quotation marks and newlines.
(Note the two new lines in the lambda of the ble_client).
I can not really test this myself, this is a suggestion from ChatGPT. Let me know if it works or not

If it works you might want to try reducing the amount of data its processing, for example by setting a global counter initially zero, then on every ble receive in the lambda increase the counter till for example 10, if it hits ten do the rest of the code and reset the counter to 0, so it skips 0 - 9 and does processing only for the 10th receive.

Actually, looking at the log part you posted again, looks like its submitting it to the notify in segments?
Then my previous post wont work.
Can you try posting a bit longer result from the logs (like the one you posted with the Other errors, where it says Received data too short) so i can try figuring out if it has a repeating pattern ?
Basicly what needs to happen is identify how many segments it posts and putting them together, then process them. Challange in this is going to determine the start of each set of segments

Its a bit of a guess since i can not properly test, but something like might work, it does compile but since i do not have the same battery its a bit hard to test. As a last resort i could program a second esp to act as the battery.

Note the new global which is a buffer for the incoming strings, every ^ basicly starts the string by looking for it as the first character, then if the character is not found it will add it to the rest, once its found again it will process the data first and reset the string to the new found first segment. This should also solve the issue of flooding the processor for the processing of the strings as its actually quite a few less then assumed but broken up.

If it is still too much data then implementing the counter is still an option.

Did you see this?

It’s a bit hard for me to follow you here

devilmastah · June 24, 2024, 5:23am

i must have missed it, anyhow, just try the last code version i posted
I think it should already have a repeating pattern since every new batch of data starts with the ^, so it might already be solved.

If it does not work ill code up a fake battery later today that acts in the way yours seems to do so i can figure out how to fix it.

I Used the code from post PowerXtreme / Emergoplus BLE Battery - #23 by devilmastah

It’s doing something now, but not totally correct:

One more set of output if it helps:

One annoying thing is as soon if the ESP is in the range of the battery I cannot flash it. It always fails at 4-5%. It must be too busy. Anything doable to that? Filter? Or is it the internals too busy with parsing the messages?

marcelt · August 12, 2024, 11:53am

I have a powerextreme x125. I guess this must also work for this device?

sender · August 12, 2024, 1:57pm

Try it? Then you’ll know…

marcelt · August 12, 2024, 2:48pm

I will try it. But I was wondering if someone else already tried.

marcelt · August 19, 2024, 2:13pm

@sender Unfortunately, it did not work. I have a similar as you. These weird numbers do not make sense. I have also the problem that I cannot flash it anymore if it is connected to the battery.

So I would like to start on the beginning to make sure I got the right string.
@devilmastah Which OS app are you using (Do you have a link to the app-store?) and what steps do I need to do to get this long string in the App? Are able to provide this. Can you make your decode script available? Or when I have the string can I sent it to you to see if it is similar?
And lastly, do you see something in the decompile code of the app that different version of the battery are treaded differently?
Sorry for all the questions. Hopefully we can get this to work and when I do I will post also a fully working script.

sender · September 14, 2024, 5:30pm

I had it running partially… it works well, but I cannot “access” the esp anymore (update) if ble is connected. Tried to work it out with the expert (@devilmastah) but he’s not responding anymore… Hope someone else is able to help out because I really like this concept!

## To find the mac adress, most easy way is to enable the part down below saying:
##   - platform: ble_scanner
##     name: "BLE Devices Scanner"     
## This will show all found BLE devices in the area with their mac adres and name if they have one in the esphome log.
## In case of a X210 battery the macs start consistently with: DC:0D:30:
