Victron Energy VRM API -- monitor and control solar installations, batteries, inverters, and energy systems via the Victron Remote Management portal

Source: Victron Energy VRM REST API v2

Credits: Dunkel Cloud GmbH -- maintainer Updated: 2026-03-31

Coverage

82% (41 of ~50 endpoints)

Focus: auth, users, installations, stats, widgets, diagnostics, alarms, data export, GPS, tags, dynamic ESS, firmware, data attributes

Missing: admin endpoints, access token CRUD, installation settings write, alarm acknowledgement

Last reviewed: 2026-03-31

Setup

  1. Log in to the VRM Portal at https://vrm.victronenergy.com
  2. Navigate to Preferences → Integrations → Access tokens
  3. Click 'New token', give it a descriptive name
  4. Copy the generated token immediately -- it is shown only once
  5. Store the token prefixed with 'Token ' (e.g. 'Token abc123def456') in the credential store

Environment variable: CREDENTIAL_VICTRON_VRM_TOKEN

Authentication docs ↗

Personal Access Tokens bypass the login flow entirely. Use /users/me to get your idUser, then /users/{idUser}/installations to discover your sites. The token has full access to all installations the VRM user can see.

Install

Add to your backends.yaml:

- name: victron-vrm
  transport: rest
  dadl: /app/dadl/victron-vrm.dadl

Set the credential:

CREDENTIAL_VICTRON_VRM_TOKEN=your-token-here
