Goal

The Goal of this card is to provide an easy to understand and visualize way of displaying the current Power Distribution coming from and to different sources, such as solar, grid, home batteries etc. Furthermore, this card aims to expose a lot of customizability and control of its behavior to the configuration, allowing users to tailor it to their specific requirements.

Scope

This card does not aim to display Energy Values (Meaning accumulated power over 1 day, for example). If this is your goal, check out the Energy Flow Card Plus.

Installation

HACS (recommended)

This card is directly available through HACS. To install HACS, follow these instructions. After having HACS installed, simply search for "Power Flow Card Plus" and download it using the UI 🙂

Manual install

  1. Download and copy power-flow-card-plus.js from the latest release into your config/www directory.

  2. Add the resource reference as decribed below.

Add resource reference

If you configure Dashboards via YAML, add a reference to power-flow-card-plus.js inside your configuration.yaml:

resources:
  - url: /local/power-flow-card-plus.js
    type: module

Else, if you prefer the graphical editor, use the menu to add the resource:

  1. Make sure, advanced mode is enabled in your user profile (click on your user name to get there)
  2. Navigate to Settings -> Dashboards
  3. Click three dot icon
  4. Select Resources
  5. Hit (+ ADD RESOURCE) icon
  6. Enter URL /local/power-flow-card-plus.js and select type "JavaScript Module". (Use /hacsfiles/power-flow-card-plus/power-flow-card-plus.js and select "JavaScript Module" for HACS install if HACS didn't do it already)

Usage

⚠️ This card offers a LOT of configuration options. Don't worry, if you want your card's appearance to match the oficial Energy Flow Card, you will only need to setup the entities. The rest of the options only enable further customization. If this is your goal, please go to Minimal Configuration


⚠️ Version 0.1 introduced the UI Editor. This Editor is currently incompatible with Card Mod. I created a PR to fix this issue, but it hasn't been merged yet. Here is the PR #277. Since it hasn't been merged yet, I also released a fork with the changes from the PR. Installing this Version of Card Mod you can use this card in conjunction with Card Mod. Here is my fork

calculate_flow_rate boolean or number false If set to true, the flow rate will be calculated by using the flow rate formula (either the new or the old one, depending on your configuration). If set to a number, the flow rate will be set to that number. For example, defining the value 10 will ensure one dot will flow every 10 seconds.

Color Object

Name Type Description
production string HEX value of the color for circles labels and lines of production.
consumption string HEX value of the color for circles labels and lines of consumption.

Split entities

Can be use with either Grid or Battery configuration. The same unit_of_measurement rule as above applies.

Power Outage

This feature allows you to configure how the card handles a Grid Power Outage scenario.

Name Type Description
entity string required Entity ID providing a state that changes when there is a Power Outage. (eg: binary_sensor.grid_connection_status). Doesn't need to be a binary_sensor.
state_alert string The state the provided entity is at when there is a power outage. Default is on, meaning if the entity's state is on the card will assume there is a power outage.
icon_alert string An icon path to be override the grid icon when there is a power outage. Default is mdi:transmission-tower-off.
label_alert string A text that will be displayed below the icon when there is a power outage.
calculate_flow_rate boolean or number false

This object allows you to control the behavior of the flow lines that are inactive.

Name Type Description
mode string Valid Options are: show, hide, transparency, grey_out, custom
transparency number A number between 0 and 100. 100 means the line doesn't show at all. 0 means the line shows in full opacity. Default is 50. Will be used when the mode is either transparency or custom.
grey_color string or list of numbers Either a HEX Code or a List of three numbers between 0 and 255 in RGB order. Will be used when the mode is either grey_out or custom.

Minimal Configuration

Don't forget to change the entity ids

The following configurations will allow you to achieve your results with the least amount of lines of code / complexity. In these examples I decided to use the Split entities option, but feel free to use the combined entity option. More Info

Flow Formula

This formula is based on the official formula used by the Energy Distribution card.

max - (value / totalLines) * (max - min);
// max = max_flow_rate
// min = min_flow_rate
// value = line value, solar to grid for example
// totalLines = gridConsumption + solarConsumption + solarToBattery +
//   solarToGrid + batteryConsumption + batteryFromGrid + batteryToGrid

New Flow Formula

In contrast to the old flow formula, this formula calculates the flow rate independently from other lines, making it more intuitive to interpret the perceived power. This means that a state of 10W will always flow with the same velocity, no matter what other lines are doing. In other words this flow rate is calculated in absolute and not relative values.

To get this new Flow Formula to work, simply set use_new_flow_rate_model in the main configuration to true. You may want to play around with the max_expected_power, min_expected_power, max_flow_rate and min_flow_rate to get the speeds that you wish

if(value > maxIn) return maxOut; // In case power exceeds maximum expected power, use the fastest speed and ignore the rest.
return ((value  -  minIn) * (maxOut  -  minOut)) / (maxIn  -  minIn) +  minOut;

// value = value of the current line to calculate (eg: grid to home)
//
// minIn = amount of watts at which the lowest speed will be selected. 
//   ↳ In your configuration this is `min_expected_power`
//   ↳ eg: setting this at `100` means that at `100` watts, the dots will still flow at the lowest speed
// maxIn = amount of watts at which the highest speed will be selected. 
//   ↳ In your configuration this is `max_expected_power`
//   ↳ eg: setting this at `2000` means that everything more than `2000` will flow at the highest speed selected
//
// minOut = amount of watts at which the lowest speed will be selected. 
//   ↳ In your configuration this is `max_flow_rate`
//   ↳ eg: setting this at `5` means that one dot will take `5` second to travel
// maxOut = amount of watts at which the highest speed will be selected. 
//   ↳ In your configuration this is `min_flow_rate`
//   ↳ eg: setting this at `1` means that one dot will take `1` second to travel

The following video aims to show the diffence between the two flow formulas:

REC-20230412155142.mp4

Notice that when the Power changes to only coming from the sun, the old formula accelerates to maintain a constant amount of dots/second. Using the new formula is more intuitive, since you can immediately see that the Solar Power is relatively low since the dots are flowing very slowly. On the old Flow Formula you might think that the sun is producing a lot of power, which in this case is not true.

At the end of the day these are two options and depending on what you're interested, one might suit you better than the other, that's why I kept the old formula, you have the choice. 🙂

To-Do List

Here is my to-do list containing a few enhancements I am planning in adding. The ones at the top are bigger priorities, so they’ll probably be available before the ones at the bottom.

  • Change Tap Action Behavior to be compatible with Browser Mod
  • Fill the circles #89
  • More than two Individual Devices #54
  • More than one solar source #23
  • Add Generator Functionality #110
  • Display Connected/Disconnected status #111
  • Grid Feed In Circle #119
  • Improve performance #144

I am still just one person working on this project and obviously have other things going on in my life, so feel free to contribute to the project. You can also feel free to create a PR with a new feature and I'll try my best to review it 😊
