hello sir,

For a project, I have to find a way to import individual data from the smart shunt. To get the data dump in the first place I have used python code from Github. Using a VE direct cable I was able to get data every second. The problem is that I only need the voltage, current, power and SOC and not all data that the smart shunt sends every second. Do you have an idea how to only get the right data from the data dump?

All information that I used to get the data from the smart shunt you can find here karioja/vedirect.

your sincerely, livestyle4

Thank you for this amazing project!

Just fixing a minor typo. Validated this way https://github.com/yoannchaudet/ESPHome-configuration/blob/e6c90b78f7b12b94a25da9e6fff9f8ae660733fe/device.shed-controller.yaml#L79.

It's a breaking change since the typo was in the sensor name.

Hi,

I've spent hours trying trying to make this work, but no such luck. Do I have a defective board? Arduino: 1.8.15 (Windows 10), Board: "SparkFun ESP32 Thing, 80MHz, Default, 921600, None"

Do you agree to rename this component to victron_smart_shunt? Without the name clash between VictronMPPT-ESPHOME and VictronSmartShunt-ESPHOME both components could be used simultaneously at the same ESP (on different UARTs).

For the SmartShunt, the TX pin seems to be next to the VCC pin rather than next to GND as was shown in the first drawing (the second drawing for the UART-TTL was correct). Additionally, the orientation of the UART-TTL jack drawing has been rotated to reflect the orientation on the Victron SmartShunt. The required UART section was also added to the sample yaml configs.

Hello, i just wanted to ask if the victron BMV 700 is supported. Victron itself says that the smartshunt is a BMV 712 just without display and potential free relay. The BMV 700 is a BMV 712, just without bluetooth and the ability to measure the middle voltage of a battery bank. So it should not be so hard to support it, if it doesnt work right now, should it?

This PR addresses https://github.com/KinDR007/VictronSmartShunt-ESPHOME/issues/18.

Creates a battery_temperature sensor that returns a value when a temperature probe is connected to the auxiliary port of a Smart Shunt.

Tested with my setup:

Thank you for this amazing project!

Hi, [request for enhancement]

Would it be possible, please, to add an entity into the code to allow Home Assistant to pick it up for Baterry monitoring (Energy dashboard)?

Hi thanks for your great job to ESPhomify this Victron device. Seems Victron released the BLE protocol: https://community.victronenergy.com/questions/93919/victron-bluetooth-ble-protocol-publication.html

Maybe there is a hope to add it in your current implementation ?

Hello,

First of all, this is awesome. Thanks for putting this together, worked like a charm.

I have a VictronSmartShunt with a temperature sensor connected to the aux, would it be possible to pull temperature?

Cheers, Dick
