EV battery dynamic icon

[anthonws]

Hi!

I’m using OVMS along with my Kia Soul EV. Was using Server 2 (HTTP API) and transitioned to Server v3 (MQTT).

Have all of the data working properly, but one of the frontend elements is not working as expected. I wanted to show the battery icon based on the state of the sensors, but no icon is represented when using the below code.

Any hints?

sensor:

  - name: ovms_kia_charge_status
    state_topic: ovms/user/MYCAR/metric/v/c/charging
    availability: 
      topic: "ovms/user/MYCAR/metric/s/v3/connected"
      payload_available: "yes"
      payload_not_available: "no"
      
  - name: ovms_kia_soc
    state_topic: ovms/USER/MYCAR/metric/v/b/soc
    unit_of_measurement: "%"
    device_class: battery
    availability: 
      topic: "ovms/USER/MYCAR/metric/s/v3/connected"
      payload_available: "yes"
      payload_not_available: "no"

Hey - what is OVMS and what are you using MQTT for with your car? I like the idea of having my car data available on my MQTT server - but I don’t think I’ve seen any integration that offers that. So, I’m sorry I can’t help you with your problem - but I’m very curious about what you’re doing.

The reason I ended up here was because I was searching for the reason my Tucson Plug-In Hybrid seemed to not be refreshing the battery state of charge. The battery sensor currently is displaying 76% when I know it’s just finished charging and is actually 100%.

I ended up looking through all of the “state” data to try and find where it was picking up the 76% from - and I found it! And I also found the 100% I was looking for.

I see in the json:
/vehicle_data/status/battery/batSoc: 76
/vehicle_data/status/evStatus/batteryStatus: 100. So, my best guess at this point is that the 76% I’m seeing might actually be referring to the 12V battery? And the EV Battery charge level is the 100.

This has had me scratching my head for 2 weeks - and I thought it just wasn’t updating properly - but this would explain it - so I’m recording it here so that someone can confirm (or re-educate me) and so hopefully the next person isn’t stuck scratching their head for nearly as long as I did.

Could you use device_class: battery instead of the icon code ? I think the icon is generated from a state value in percent.

I think the code above is not working as the state will probably be a string and you’re testing for a number.

Here is the link for the OVMS project: https://www.openvehicles.com/. Please be warned that I do not recommend this unless you are a major tech savvy with electronics and programming (which I am not, hence why I forgo the whole project).

I am only looking at 2 sensors. 1 for whether the car is charging or not and the other is the soc level. 12v reports to another sensor.

I actually see that the initial sensors that I put in the post where not the correct ones (fixed :P).

Thanks!

[anthonws]

It was already defined as a battery class. But the problem is that the sensor by itself does not report charge state.

There’s 2 different sensors that make up what I want to achieve (battery level and charge state [Yes or No]).

You’re point about being a string might be the right direction. How could I do the comparison in that code for a string value?

Thanks for that link. The project looks really interesting - but seems like it requires custom hardware and is targeted at full EV owners. Mine is just a PHEV.

But if you’re only looking for 2 data points, have you tried getting them from the KIA_UVO integration?

Kia Uvo Integration

I have baked a custom integration for EU Kia Uvo, this will be working for new account types. Thanks for your hard work @wcomartin You can install this either manually copying files or using HACS. Configuration can be done on UI, you need to enter your username and password, (I know, translations are missing!). it will only fetch values for the first car, I am not sure if there are people outside using Kia Uvo with multiple cars update - It will fetch the cached information …

I’ve been using it for a couple of weeks and it seems pretty reliable. It’s not going to provide everything that the OVMS project does, but it might have what you need. Here’s a photo of my (work-in-progress) dashboard for the car which highlights many of the sensors the integration creates:

Something like this ?

icon: |-
  {% set soc = states('sensor.ovms_kia_soc') | float(0) %}
  {% set charge = states('sensor.ovms_kia_charge_status') %}
  {% if soc == 100 %}
    {% if charge == 'no' %} mdi:battery {% else %} mdi:battery-charging {% endif %}
  {% if soc >= 90 %}
    {% if charge == 'no' %} mdi:battery-90 {% else %} mdi:battery-charging-90 {% endif %}
  {% if soc >= 80 %}
    {% if charge == 'no' %} mdi:battery-80 {% else %} mdi:battery-charging-80 {% endif %}
  {% if soc >= 70 %}
    {% if charge == 'no' %} mdi:battery-70 {% else %} mdi:battery-charging-70 {% endif %}
  {% if soc >= 60 %}
    {% if charge == 'no' %} mdi:battery-60 {% else %} mdi:battery-charging-60 {% endif %}
  {% if soc >= 50 %}
    {% if charge == 'no' %} mdi:battery-50 {% else %} mdi:battery-charging-50 {% endif %}
  {% if soc >= 40 %}
    {% if charge == 'no' %} mdi:battery-40 {% else %} mdi:battery-charging-40 {% endif %}
  {% if soc >= 30 %}
    {% if charge == 'no' %} mdi:battery-30 {% else %} mdi:battery-charging-30 {% endif %}
  {% if soc >= 20 %}
    {% if charge == 'no' %} mdi:battery-20 {% else %} mdi:battery-charging-20 {% endif %}
  {% if soc >= 10 %}
    {% if charge == 'no' %} mdi:battery-10 {% else %} mdi:battery-charging-10 {% endif %}
  {% if soc < 10  %}
    {% if charge == 'no' %} mdi:battery-alert-variant-outline {% else %} mdi:battery-charging-outline {% endif %}

I appreciate the reply and info, but my car does not support KIA_UVO (aka Kia Connect). Hence why I use OVMS.
OVMS is the “custom hardware”. It comes pre-assembled and with the needed firmware. It is “almost” plug & play.

[anthonws]

I will try and share feedback ASAP! Thank you very much!!

[tenly (Jim)]

@anthonws That makes perfect sense. So this OVMS project is a solution for people that can’t use the BlueLink or KIA_Connect service? It might be worth looking into once my free BlueLink subscription expires! That’s a year away - and by then you’ll be an expert on the system and be able to answer all my questions!

Good luck. I hope you get your problem solved!
