oomi-influx 0.4.0

ETL ingestion of Oomi energy data into InfluxDB

oomi-influx

Headless ETL tool that pulls 15-minute electricity consumption data from the Oomi customer portal and writes it directly to InfluxDB 2.x.

No browser. No GUI. Designed to run unattended on a Raspberry Pi or any Linux server.

How it works

Oomi's portal runs on Salesforce Experience Cloud and exposes no public API. oomi-influx replays the same HTTP calls the browser makes:

1. Form-POST login → Salesforce session ID
2. Frontdoor handshake → community session cookie + Aura token
3. POST to the Aura API (oomi_ConsumptionController.getConsumption) → NDJSON

Each consumption slot is a 15-minute UTC-timestamped record written to InfluxDB as:

InfluxDB concept	Value
Measurement	electricity_consumption (configurable)
Tag	metering_point=<value> (configurable)
Fields	consumption_kwh, consumption_wh, resolution (configurable)

Requirements

• uv
• An Oomi customer account with smart meter access
• InfluxDB 2.x instance

Installation

Install as a persistent uv tool (puts oomi-influx on your PATH):

uv tool install oomi-influx

To try it without installing:

uvx oomi-influx --help

Configuration

Create a directory to hold the configuration, then run the interactive setup wizard from it. The wizard logs in, fetches your meter details automatically, and writes .env to the current directory:

mkdir ~/oomi-config && cd ~/oomi-config
oomi-influx configure

The wizard uses any existing .env values as defaults, so re-running it only asks you to confirm or change individual values.

.env is read from the working directory. Always run oomi-influx from the directory that contains your .env, or set the variables in your environment directly.

Environment variables

oomi-influx configure writes all required variables to .env for you. If you prefer to set them manually, create .env in your config directory with the following variables:

Oomi

Variable	Description
OOMI_USERNAME	Your Oomi login email
OOMI_PASSWORD	Your Oomi password
OOMI_GSRN	Your meter EAN (18-digit; fetched automatically by configure)
OOMI_CUSTOMER_ID	Salesforce customer identifier (fetched automatically by configure)

InfluxDB

Variable	Description	Default
INFLUX_URL	InfluxDB base URL	—
INFLUX_TOKEN	API token with write access to the bucket	—
INFLUX_ORG	Organisation name	—
INFLUX_BUCKET	Destination bucket	—
INFLUX_MEASUREMENT	Measurement name	electricity_consumption
INFLUX_TAG_KEY	Tag key	metering_point
INFLUX_TAG_VALUE	Tag value (your meter identifier)	—
INFLUX_FIELD_KWH	Field name for kWh value	consumption_kwh
INFLUX_FIELD_WH	Field name for Wh value	consumption_wh
INFLUX_FIELD_RESOLUTION	Field name for slot resolution	resolution

Never commit .env — it is git-ignored. The repository is public.

Usage

Fetch consumption data (stdout)

# Last 7 days (default)
oomi-influx fetch consumption

# Specific range
oomi-influx fetch consumption --start 2026-05-01T00:00:00Z --end 2026-05-14T00:00:00Z

Output is NDJSON on stdout, one record per line:

{"timestamp": "2026-05-14T06:00:00+00:00", "kwh": 0.662}

Write consumption data to InfluxDB

# Last 7 days (default)
oomi-influx write consumption

# Specific range
oomi-influx write consumption --start 2026-05-01T00:00:00Z --end 2026-05-14T00:00:00Z

Fetches from Oomi and writes directly to the configured InfluxDB bucket in one step.

Running on a schedule

systemd timer (recommended for servers)

Create /etc/systemd/system/oomi-influx.service:

[Unit]
Description=Fetch and write Oomi consumption data to InfluxDB

[Service]
Type=oneshot
User=<your-user>
WorkingDirectory=/home/<your-user>/oomi-config
ExecStart=oomi-influx write consumption

Create /etc/systemd/system/oomi-influx.timer:

[Unit]
Description=Run oomi-influx every hour

[Timer]
OnCalendar=hourly
Persistent=true

[Install]
WantedBy=timers.target

sudo systemctl enable --now oomi-influx.timer

WorkingDirectory should point to the directory that contains your .env. oomi-influx is the binary installed by uv tool install — confirm its path with which oomi-influx and use the full path if systemd cannot find it.
