Reading Victron Bluetooth advertising protocol in Shelly script

[xnd]

 

Question

Anyone able to implement reading data from Victron devices? It is: Victron Bluetooth advertising protocol

More info:

- details: https://community.victronenergy.com/storage/attachments/48745-extra-manufacturer-data-2022-12-14.pdf

I'm able to read that data via script on my Shelly Plus Plug S but that data are encrypted.

Quote

The encryption is done using a **AES-CTR operation**

Shelly scripting environment is very limited and I'm unsuccessful with decrypting that data yet.

 

Thank you

 

i'm using basic template for reading BLE data:

let SCAN_DURATION = BLE.Scanner.INFINITE_SCAN;

function scanCB(ev, res) {
  if (ev !== BLE.Scanner.SCAN_RESULT) return;
  if (typeof res.local_name !== 'string') return;
  
  if (res.local_name.indexOf('SmartSolar') < 0) return;
  
  try {
    console.log('== ' + res.local_name);
    const raw_data = res.manufacturer_data['02e1'];
    console.log(String(raw_data));

  } catch (e) {
    console.log('ERR', e);
  }
}

BLE.Scanner.Start({ duration_ms: SCAN_DURATION, active: true }, scanCB);

Is it possible to implement AES-CTR in shelly scripting?

[Kappe]

Are there any news about that ? as far as i could find out the shelly script is not able to do aes decryption... anyway if it is possible to transfer the data to nodered for example, it would be possible... i have tested mqtt but i can´t figure out how the rawdata is formatted....

hi everyone, I have also the need to transfer data from viktron devices, like Smartsolar, to eg Homeassiatant through an Shelly 1 plus. 
but first of all, I not see any data in my log when I start this script

My following Setup:

- Victron MPPT BlueSolar 

- Victron Smart Shunt IP65

- Victron Phoenix Inverter 24/1200 (VE Bluetooth Dongle)

- Shelly Plus 1 as BLE Proxy
