Reading Victron Bluetooth advertising protocol in Shelly script


Recommended Posts



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.


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:


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'];

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

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