I had no problem adding the setup info and connecting to my MQTT broker to my ESP32 but could not find anywhere that ESPHome would allow me to add a global throttle. Rather than add a throttle to each topic, I ended up using your VictronMPPT-ESPHOME/smartshunt-esp8266-example.yaml and modifying it for an ESP32 (it's working great even though I find the MQTT topic structure to be rather long-winded).

I tried this first as I only have the SmartShunt and was using the ESP32 but it didn't suit my needs without being able to throttle down the runaway messages I was getting.

Hi,

I've spent hours trying trying to make this work, but no such luck. Do I have a defective board?

hello, Im trying to create a temple to display my battery
remaining capacity in Ah.

here is my code:

- platform: template 
   name: " ${devicename} rem. capacity " 
    id: rc 
    unit_of_measurement: Ah 
    device_class: energy 
    state_class: total_increasing 
    accuracy_decimals: ${accuracy} 
    lambda: |- 
          float i = 0.0;  
          float e = id(bv).state; 
          float w = id(kWhc).state; 
          if (w > 0) { 
            i =  w / e; 
          } 
          return {i}; 

but I get the flollowing error:

I do have a similar template for battery charge in kWh and that one works:

- platform: template
    name: " ${devicename} charge "
    id: kWhc
    filters:
      - multiply: 0.001
    unit_of_measurement: kWh
    device_class: energy
    state_class: total_increasing
    accuracy_decimals: ${accuracy}
    lambda: |-
          float i = 264 + id(consumed_amp_hours).state; 
          float e = id(bv).state;
          float w = 0.0;
          if (i > 0) {
            w =  i * e;
          }
          return {w};

I just added the id:kWhc to name: " ${devicename} charge "
please advice.
best regards,
Miguel

Hello,

is there a way to get the current status (open or closed) of the relay from an BMV 700?

Thank you

Hello to everyone,
I installed my second battery pack with second Victron Smart shunt. I set-up the esp8266 as the first one, and i pasted same code of the first one, but doesn't work.
In the working one, there are 38 items, and in the new one there is only one entity.

Would same one help me to find the problem?
Thank you for your help

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

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)?

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?

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

the other threat was close.
sorry if I doble posted.
in regars of issue #33

I got this device and it resets to 100% every single day between 8 am and 9 am, also my %SoC has some really weird spikes of 900%.
i dont think that is the yaml code but definitely theres something wrong.

I have connected the posisitve of the smart shunt to the positive of the batterty and the shart shunt in series with the load and the smartshunt TX to esp8266 D7. no GND to the VE.DIRECT port, but that doesnt eplain why the smart shunt restest to 100% by itself.

Best Regards,
M.

It is possible to combine both projects? Could you point out the differences of the protocols?

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).

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 ?

Sébastien

In best case you should pick the same as the MPPT project: MIT.

has anyone tried to use the new smartshunt model
SHU065150050 IP65 . its waterproof and the ve. direct is a cable instead of a port

thanks
Miguel

so everything works and uploads fine but I can not for the life of me get it to show anything from the BMV everything is unavailable I've changed pins and everything I can think of. I checked the voltage and I should be correct haha. Has anyone gotten anything other than the smart shunt to read?
