victron_ble2mqtt

Emit MQTT events from Victron Energy Solar Charger via victron-ble

Tested with:

• Solar Charger: SmartSolar MPPT 100/20
• Raspberry Pi Zero 2 W with Raspberry Pi OS Lite

Usage

preperation

victron_ble used Bleak and the Linux backend of Bleak communicates with BlueZ over DBus. So you have to install this, e.g.:

~$ sudo apt install bluez

Bootstrap

Clone the sources and just call the CLI to create a Python Virtualenv, e.g.:

~$ git clone https://github.com/jedie/victron-ble2mqtt.git
~$ cd victron-ble2mqtt
~/victron-ble2mqtt$ ./cli.py --help

Setup Device

Detect your device first, e.g.:

~/victron-ble2mqtt$ ./cli.py discover
...
{
    'name': 'SmartSolar HQ2248AM79D',
    'address': 'E7:37:97:XX:XX:XX',
    'details': {
        'path': '/org/bluez/hci0/dev_E7_37_97_XX_XX_XX',
        'props': {
            'Address': 'E7:37:97:XX:XX:XX',
            'AddressType': 'random',
            'Name': 'SmartSolar HQ2248AM79D',
            'Alias': 'SmartSolar HQ2248AM79D',
            'Paired': False,
            'Trusted': False,
            'Blocked': False,
            'LegacyPairing': False,
            'RSSI': -89,
            'Connected': False,
            'UUIDs': [],
            'Adapter': '/org/bluez/hci0',
            'ManufacturerData': {737: bytearray(b'...')},
            'ServicesResolved': False
        }
    }

Device Key

You need the Device MAC address and the key.

The easiest way to get the device key: Install the official Victron Smartphone and and copy&paste the key:

• Click on your SmartSolar device
• Go to detail page about the SmartSolar Bluetooth Interface
• Click on SHOW at Instant readout via Bluetooth / Encryption data
• Copy the Connectionkey by click on the key

(I send the key via Signal as "my note" and use the Desktop Signal app to receive the key on my Computer)

setting

Just call edit-settings command, e.g.:

~/victron-ble2mqtt$ ./cli.py edit-settings

At least insert your MQTT settings and the device MAC and key.

Test

Start publish MQTT endless look, just call publish-loop command, e.g.:

~/victron-ble2mqtt$ ./cli.py publish-loop

setup systemd services

Check systemd setup:

~/victron-ble2mqtt$ ./cli.py systemd-debug

Setup services:

~/victron-ble2mqtt$ ./cli.py systemd-setup

Check the services:

~/victron-ble2mqtt$ ./cli.py systemd-status
