Victron MPPT 75/10 ble with OpenMQTTGateway

Compatible devices
1

Hi,

I’m trying to retrieve data from a Victron MPPT 75/10 and send it to my home automation system (Jeedom) via Bluetooth Low Energy (BLE) using ESP32 antennas that are already set up for other BLE devices, and thus OpenMQTTGateway.
I saw that this is possible with certain Victron devices in your compatibility list, but I couldn’t find anything regarding my model.
Bluetooth is enabled on the Victron, and I have the decryption key (keybind). I can share via DM if it’s possible to integrate my model.
For now, I can only manually create the device’s topic and retrieve the RSSI, so the antenna is definitely picking up the Victron.

Regards.

Hi @nicolas.chiret

With the great help of @geekydrewbie I was able to add some Victron devices, but I also then got stuck halfway when it came to his Smart Shunt, either because I could only find some quite old documentation or because I just couldn’t get my head around it :wink:

I am currently busy with other things, but your MPPT 75/10 might be one of the better documented Victron devices, so when I have some time I could look at adding it to Theengs Decoder.

Can you turn on Advertisement and advanced data in OpenMQTTGateway and then send me some of the MQTT messages, which then also contain the undecoded manufacturerdata, in a private message here?

HI,

Tks for your answer.

{

“id”: “F3:xx:xx:xx:xx:xx”,

“mac_type”: 1,

“adv_type”: 0,

“name”: “S18 C06C LE”,

“manufacturerdata”: “a705060012202a00ca00001000000000000000”,

“rssi”: -97,

“txpower”: 0

}

EDIT: typo error in my post, it’s a 75/15 not 75/10 but a Blue Solar charge controller too (same product line)

Regards,

Thanks for the sample message, but it does look very different from other Victron devices.

Is Instant readout via Bluetooth enabled in the Victron app for your MPPT 75/15?

Are you possibly getting different MQTT messages, with the.manufacturerdata starting with e10210…?

Oh sorry, my bad.

This was not the good device :sweat_smile:

{
  "id": "F9:xx:xx:xx:xx:33",
  "mac_type": 1,
  "adv_type": 2,
  "name": "SmartSolar",
  "manufacturerdata": "e102108275a001053513a8874c8374ab762a302ee3fc",
  "rssi": -90
}

Regards

The decoder for all Victron Energy SmartSolar MPPT models has been implemented and is available with Theengs Decoder 2.2.0

Some major decryption issues in OpenMQTTGateway surfaced during the testing thought, which I’ll message to you privately @1technophile
