ESPHome Smart Battery

# esphome-smart-battery Control DIY smart battery using JBD BMS, external balancer. Monitor it with environment sensors and display. [[Project GitHub](https://github.com/odya/esphome-smart-battery)] ## Features - Grabs all BMS parameters by bluetooth and transfers it into Home Assistant - Auto balance with external balancer with flexible logic setup - Separate screen with button on battery case - Fancy card for lovelace - Adjusted SoC calculation ## Hardware [Detailed hardware description](pcb/README.md) ## Software 1) Create new project subdirectory within your ESPHome configuration directory (let it be `smart-battery`, for example) 2) Copy the contents of the `src` repo folder to a newly created project directory. 3) Now, the `main.yaml` file must be located under `<esphome_config>/smart-battery` 4) Create file `smart-battery.yaml` in the esphome config directory root and copy contents of [example config](/examples/smart-battery.yaml) 5) Edit substitutions & customize `smart-battery.yaml`. You can add contents of [common_system](/examples/common_system.yaml) & [common_sensors](/examples/common_sensors.yaml) to this file or include them separately following the example. 6) Flash firmware to your ESP32 ## Battery card For easy battery control in Home Assistant, you can use the [following snippet](/battery-card/battery-card-example.yaml). It compiles all the essential battery sensors and controls in a compact manner. The following custom plugins are used: [bar-card](https://github.com/custom-cards/bar-card), [stack-in-card](https://github.com/custom-cards/stack-in-card), [tabbed-card](https://github.com/kinghat/tabbed-card), [text-divider-row](https://github.com/iantrich/text-divider-row), [canary](https://github.com/jcwillox/lovelace-canary). ## References & thanks - This project is built around [syssi/esphome-jbd-bms](https://github.com/syssi/esphome-jbd-bms) at its core.
