Hi Robert,
thank you for your great project.
it was exactly what i was looking for.

There is only one problem when trying to process the data before it is uploaded.

sudo ./import_ble.sh
Mi Body Composition Scale 2 Garmin Connect v3.0 (import_ble.sh)

Data backup file exists, checking for new data
Importing and calculating data to upload
Data upload to Garmin Connect is complete

(I have to start it via sudo otherwise there are problems to execute/start btle.py)

but when checking the log:

cat temp.log sh: 1: /home/pi/miscale2garmin-3.0/bodycomposition: Exec format error Mi Body Composition Scale 2 Garmin Connect v3.0 (export_garmin.py) Processed file: 1644148841.tlog

If you need more information let me know.

Thanks for your effort and your time.
Cheers
Pascal

Hi,
It seems to me that there is an issue with the program's operation when the Raspberry Pi is running on Wi-Fi. Running import_data.sh as a process causes Wi-Fi problems. The Raspberry Pi continuously disconnects and reconnects to Wi-Fi. The error on the router is "DC:A6:32:66:12:88@wlan1: disconnected, extensive data loss, signal strength -66". Naturally, the data does not import into Garmin Connect. It works fine with a wired connection.

Hi, I use miscale together with my wife. She does not have garmin account so I don't need to upload her data therefore I have not added her to the users array. But her data appears in the backup.csv files and once there it stops the upload of any further readings saying "There is no user with the given weight...". Is there anyway to modify the script so it just skips her data based on max weight?

I successfully used one of the previous versions - v4.8 of the scanner_ble_py file. Unfortunately, with the new one I am getting a syntax error

    Unix_time = int(dt.timestamp(dt.strptime(f"{int((data[3] << 8) | data[2])},{int(data[4])},{int(data[5])},{int(data[6])},{int(data[7])},{int(data[8])}", "%Y,%m,%d,%H,%M,%S")))
                                                                                                                                                         ^

also

During preparation

sudo setcap 'cap_net_raw,cap_net_admin+eip' /usr/local/lib/python3.9/dist-packages/bluepy/bluepy-helper`

gives me an error

Failed to set capabilities on file `/usr/local/lib/python3.9/dist-packages/bluepy/bluepy-helper' (Invalid argument)
The value of the capability argument is not allowed for a file. Or the file is not a regular (non-symlink) file

As the tittle sugeest....i get the error
sh: 1: /home/pi/miscale2garmin-3.0/bodycomposition: Exec format error

Any suggestions on what could be the issue?

Hi,
Can we run this code as Docker container ?

Hi, I have a problem to make scripts work properly. Reading complete data from scale works only while I'm standing on it. If not, hasImpedance variable always results in 0, so i get incomplete data as output and therefore, upload to garmin connect fails.

I've noticed that if i turn of "weigh small object" option in dedicated app, i can get proper results almost every time event when i'm not standing on scale anymore. I wonder if anyone experienced this bahavior. It's weird because app gets results everytime, despite of selected options.

I'm using scripts with rPi4 if that matters.

Hello, could you make an android app?

Hi Robert, since weightlogger no longer works with Garmin after 2fA, I am using miscale2garmin and it works great. Thank you. Entering weight in kgs adds another step (conversion in a calculator) which though trivial, is needed each and every time.

Are reason you would not consider adding weight entry in pounds?

thanks, mike

``Hello Robert,
regarding to your advice I changed BT adapter to EDUP EP-B3536 based on RTL8761B chipset.
previously my adapter was able to scan but I had problem with range - my bathroom is next to room when I have PC with miscale2garmin software - there's one ytong wall between.
My USB port is passed through from proxmox to VM with Debian 11.
I installed firmware was you stated and even tried firmware from Debian Repo (backports non-free)
when i run scan nothing shows:

  can you please help me with diagnostics?

There were some problems with my bluetooth adapter interface during installation. In your code, you are using the hci0 interface of the bluetooth adapter by default.
This can be problematic for people who have multiple bluetooth adapters.

I just had to add a parameter to the Scanner function in the scanner_ble.py file - line 50 (in my case the bluetooth adapter is on the hci1 interface):

scanner = btle.Scanner(1).

I suggest adding this information to the README. It may help many people :)

Thanks!

Hello Robert,
sorry, my english is not good, this is google translated.
I came across your project more by accident and that would be perfect for me, I have a Garmin fenix 6 for a short time and have had a Mi Scale 2 for a while (2020), now merging the values of the scale with Garmin Connect without going through others Apps would be perfect. But I have absolutely no idea about Arduino. I've now bought the hardware for your project and managed to get the program onto the ESP32 Pro. Aunt Google also helped me to "decrypt" the cryptic letters in the serial monitor (baud rate must be set to 115200) but now I can't go any further ☹.
It scans and finds the scale but aborts with "Reading BLE data incomplete, finished BLE scan"

What can be the reason, where can I start?

What about create *.apk to get data from phone and send to garmin connect?

Hi Robert,
I would like to report time zone mismatch between scale and OS (raspberry OS in my case).
I carefully followed your instructions how to set correct date and time for scale, but it didn't work for me. No matter what I do, it still returns UTC time, so time doesn't match for me. My local time is UTC+1 summertime so it's 2 hours difference. I was forced to modify import_data.sh and change threshold value from 1200s to 8400s (1200 + 7200(2 hours difference between scale and local time)).
I'm not sure if different account for Zepp Life (I use Mi account currently) will fix/change time. I can try this.
Anyway, I know how hard is to work in environment with multiple time zones. In such cases where scale doesn't respect local time it would be handy to have feature to apply some kind of offset automatically (like I did manually) by prompting user if he wants to apply time difference offset.

I still never worked with ESP and Arduino, but already bought the WeMos d1 Mini Module.

I have a body composition scales, and am wondering if it's possible to hide the module inside.

Batteries are ok, they have enough juice. What if to connect module to batteries, but to send in the deep sleep forever. But when the last segment of body composition bar lights up, to load module, connect it to Wifi, query the scales by BLE, send the data, and then to go back to sleep?

Or it's just a plain dumb idea of the battery killer?

Hello, I am hoping for some pointers on how I could further troubleshoot this issue I am experiencing: Here is the temp.log after running import_data.sh

jtuck@raspberrypi-scale:~/miscale2garmin-5 $ cat temp.log
Segmentation fault

Mi Body Composition Scale 2 Garmin Connect v5.9 (export_garmin.py)

I scan run the scanner_ble.py manually and it runs as expected. Running import_data.sh seems to work providing the following output, but I can't find any results in Garmin that it actually uploaded and checking the temp.log is where I found the "Segmentation Fault"

jtuck@raspberrypi-scale:~/miscale2garmin-5 $ ./import_data.sh

Any ideas for how I can get to the bottom of my issue?

Hi, first of all, thanks for this project, seems like a life saver for Garmin users.
I've recenetly setup miscale2garmin an I'm strugglin to get data on Garmin connect, everything seems fine. but nothing appears on Garmin Connect:

* temp.log file exists, checking for new data
* Importing data from a BLE scanner
* Saving import 1674745428 to backup.csv file
* Calculating data from import 1674745428, upload to Garmin Connect
* Data upload to Garmin Connect is complete
* Saving calculated data from import 1674745428 to backup.csv file```
The only strange thing I've notice is some really big offset, that I bypass by setting `offset: -11000`

Backup file seems fine:

What could be failing ?

I am collecting the data from the Mi Scale 2 via Mqtt with Home Assistant (https://github.com/dckiller51/bodymiscale). Could that data be used to send it to Garmin Connect? If I understood how python files work, I think it would be easy to do, but it's beyond me. External projects can be integrated into Home Assistant via HACS. In fact, I see that your project is based on one of the projects that collect the data from the scale and send it to the Home Assistant. Could your project be integrated into Home Assistant? Sorry if I said nonsense. Thanks in advance.

Hi, I have set up all things according to the guide, but the "scanner_ble.py" gets always "Reading BLE data incomplete". I downloaded the new version 4.8 but this still gets the same message.

Thans for your great job.

You make one mistake in import_data.sh

Hello,

I tried to build ESP32 project and I am unable to do it because I getting error of compiled program being bigger than available memory.

Flash: [==========] 111.8% (used 1465053 bytes from 1310720 bytes)

Maybe at least author can post exact versions of libraries? Because I used the newest one available.

First of all amazing project.

Some feedback after testing it. I had to recompile bodycomposition because I'm using RPi with arm64. I can provide the 64-bit version if you would wish to add it. I also had some problems with BLE scanning. Turns out when the scanning was manually stopped (instead of the timeout) it wouldn't add the last device detected (which in that case would be the MiScale). For now I just removed that line from the code and reduced scanning time to 20sec. Not sure why that happens...

Is it a way to use it on Home Assistant installed on Proxmox PVE?

Hi, I'm doing the modification for direct parsing parameters from mi scale and posting them to Garmin connect.
Could you please provide:

1. the result of doing the read_MQTT=`mosquitto_sub -h $host -t $locpath -u $user -P $passwd -C 1 (without awk addition)
2. data/backup.csv file example you receive as a result of performing the shell script?

That would greatly help me.

I have Mi Body Composition Scale 2.

It seems like the scale is returning correct mac address in Manufacturer Data Value. When I enter ec:df:ed:df:cf:ff in scanner_ble.py, ofcourse it returns valid target device, but after run import_data.sh i get this:

There seems to be a problem in the "bodycomposition" when tries to upload to Garmin
Most likely Garmin has something changed?

Hi, Robert,
looks like great work, but have a question.
I have a linux ubuntu server, it has Bluetooth built-in. Can this be somehow run on a linux machine without the need for the hardware project? I even have an mqtt server installed there, so would just appreciate some way to use the built-in BT to query the scale without building that chargeable external hardware box.
PS> I'm looking for a way to export the body parameters to garmin connect.

I am already at the final stage. The scanner_ble.py works and finds the scale with the entered address, as well as the basic measurement data. When I want to run import_data.sh I get the message

python3 import_data.sh
File "import_data.sh", line 13
echo "Mi Body Composition Scale 2 Garmin Connect v4.7 (import_data.sh)"
^
SyntaxError: invalid syntax

Could this be due to an older version of python, ora raspbian? Currently I can only test the operation on this hardware.

Hi :)

That's a great idea to export Xiaomi data to Garmin. I'm using Fenix 6 Pro so I prefer to store all my data in Garmin connect app.

I'm using Raspberry Pi 4 with latest Debian Bullseye, everything is updated :) Scale model is exact the same - XMTZC05HM. Firmware version of scale shown in Xiaomi app is 1.0.0.12.

I've run into few problems:

1. bluetooth.service had a bit different path of ExecStart - ExecStart=/usr/libexec/bluetooth/bluetoothd so i just added "--noplugin=sap". There seems no bluetooth folder in lib directory, it exists only in libexec.
2. I used armv6 version of bodycomposition (i'm not sure it's the right one).
3. I can't run any script without sudo.
4. scanner_ble.py reads data only when I'm standing on the scale, I thought it should work 15 minutes from using it (maybe I misunderstood your readme :)). The data it showed into console was: 88.65;466;1646906408;2022-3-10 11:0:8
5. export_garmin.py shows that there is no user with the given weight. I've edited the script with maxweight 95 and minweight 75 so it should work.
6. import_ble.sh shows No BLE data from scale or incomplete but I think that's because export_garmin.py isn't working.

Please don't mind if some of the problems are obvious - I'm a beginner linux user and a beginner java programmer so I may do something wrong... :)

There is more faster and powerfull metode.
No nead masquitto and mqtt broker.
Use ESPhome rot esp32 with native component xiaomi_miscale.
The other way same as in your topic.
Thanks for your work!
