IAMMETER-Docker Adds Datalogger Mode
IAMMETER-Docker is a lightweight, self-hosted energy monitoring system officially provided by IAMMETER. It allows users to deploy a private energy monitoring platform on their own server or router β completely free.
Recently, IAMMETER users suggested adding a datalogger-like feature for local data recording without Internet access. In response, the IAMMETER team has upgraded IAMMETER-Docker to include this powerful new feature.

π New Feature: Datalogger Mode
The latest IAMMETER-Docker release now supports a datalogger mode, enabling completely offline energy data logging. With just one IAMMETER meter and a Docker-capable router, users can easily record and export power data β even without Internet access.
π Typical Use Case
Imagine a remote location (such as a solar site, off-grid cabin, or factory without Internet). You can:
- Connect an IAMMETER Wi-Fi energy meter to a local router running IAMMETER-Docker.
- The meter automatically uploads its readings via Wi-Fi.
- IAMMETER-Docker stores all data locally on the router.
- You can view or download the data in CSV format anytime β through a web browser or USB drive.

βοΈ Setup Guide
Follow these steps to enable Datalogger Mode:
- Choose a router that supports Docker Typically, use an OpenWRT-based system such as FriendlyWrt or istoreos.
- Install IAMMETER-Docker Pull and run the latest version from Docker Hub.
- Configure the IAMMETER Wi-Fi meter Set the meterβs Wi-Fi connection to your routerβs access point (AP).
- Point the meterβs upload address to IAMMETER-Docker
Example:
http://{router_local_IP}:5050
π How to Access the Logged Data
Once configured, your IAMMETER meter will automatically upload and save its measurements as CSV files on the router. No need to manually add the device inside IAMMETER-Docker.
You have two options to retrieve offline data:
β Option 1: Access via Web Browser
Simply visit the following URL on any device in the same network:
http://{Local IP of IAMMETER-Docker}:5050/datalogger
Default login credentials:
- Username:
admin - Password:
admin
Once logged in, you can download or delete stored CSV data directly from the webpage.

β Option 2: USB Drive Export
If your router includes a USB port, you can enable hotplug mode. When a USB drive is inserted, the router automatically copies the latest CSV files to it β a simple way to physically export your offline data.
π‘ Recommended Router Options
If you are familiar with OpenWRT or soft router systems, you can choose any hardware you prefer. For non-technical users, IAMMETER can also provide a preconfigured router with all necessary software installed β ready to use out of the box.
