# Adafruit MAX17048 Usermod (LiPo & LiIon Battery Monitor & Fuel Gauge)
|
||
|
|
This usermod reads information from an Adafruit MAX17048 and outputs the following:
|
||
|
|
- Battery Voltage
|
||
|
|
- Battery Level Percentage
|
||
|
|
|
||
|
|
|
||
|
|
## Dependencies
|
||
|
|
Libraries:
|
||
|
|
- `Adafruit_BusIO@~1.14.5` (by [adafruit](https://github.com/adafruit/Adafruit_BusIO))
|
||
|
|
- `Adafruit_MAX1704X@~1.0.2` (by [adafruit](https://github.com/adafruit/Adafruit_MAX1704X))
|
||
|
|
|
||
|
|
These must be added under `lib_deps` in your `platform.ini` (or `platform_override.ini`).
|
||
|
|
Data is published over MQTT - make sure you've enabled the MQTT sync interface.
|
||
|
|
|
||
|
|
## Compilation
|
||
|
|
|
||
|
|
To enable, compile with `USERMOD_MAX17048` define in the build_flags (e.g. in `platformio.ini` or `platformio_override.ini`) such as in the example below:
|
||
|
|
```ini
|
||
|
|
[env:usermod_max17048_d1_mini]
|
||
|
|
extends = env:d1_mini
|
||
|
|
build_flags =
|
||
|
|
${common.build_flags_esp8266}
|
||
|
|
-D USERMOD_MAX17048
|
||
|
|
lib_deps =
|
||
|
|
${esp8266.lib_deps}
|
||
|
|
https://github.com/adafruit/Adafruit_BusIO @ 1.14.5
|
||
|
|
https://github.com/adafruit/Adafruit_MAX1704X @ 1.0.2
|
||
|
|
```
|
||
|
|
|
||
|
|
### Configuration Options
|
||
|
|
The following settings can be set at compile-time but are configurable on the usermod menu (except First Monitor time):
|
||
|
|
- USERMOD_MAX17048_MIN_MONITOR_INTERVAL (the min number of milliseconds between checks, defaults to 10,000 ms)
|
||
|
|
- USERMOD_MAX17048_MAX_MONITOR_INTERVAL (the max number of milliseconds between checks, defaults to 10,000 ms)
|
||
|
|
- USERMOD_MAX17048_FIRST_MONITOR_AT
|
||
|
|
|
||
|
|
|
||
|
|
Additionally, the Usermod Menu allows you to:
|
||
|
|
- Enable or Disable the usermod
|
||
|
|
- Enable or Disable Home Assistant Discovery (turn on/off to sent MQTT Discovery entries for Home Assistant)
|
||
|
|
- Configure SCL/SDA GPIO Pins
|
||
|
|
|
||
|
|
## API
|
||
|
|
The following method is available to interact with the usermod from other code modules:
|
||
|
|
- `getBatteryVoltageV` read the last battery voltage (in Volt) obtained from the sensor
|
||
|
|
- `getBatteryPercent` reads the last battery percentage obtained from the sensor
|
||
|
|
|
||
|
|
## MQTT
|
||
|
|
MQTT topics are as follows (`<deviceTopic>` is set in MQTT section of Sync Setup menu):
|
||
|
|
Measurement type | MQTT topic
|
||
|
|
--- | ---
|
||
|
|
Battery Voltage | `<deviceTopic>/batteryVoltage`
|
||
|
|
Battery Percent | `<deviceTopic>/batteryPercent`
|
