About

What this is

A Domoticz plugin that monitors Dell PowerEdge servers through the iDRAC's Redfish API, written by Rouzax.

It is not affiliated with, endorsed by, or supported by Dell Technologies. "Dell", "PowerEdge" and "iDRAC" are trademarks of their respective owners and are used here only to describe what the plugin talks to.

What it has been tested against

Read live from a fleet of Dell PowerEdge machines spanning two generations: R440, R740xd2, DSS8440 (14G) and R750, R7525, R7515 (15G), on iDRAC firmware 7.00 and 7.20, both standalone and OpenManage-managed.

That run covered several states a single test machine cannot produce: GPU power and temperature from a 7-card DSS8440 and a 4-card R7525, servers reporting Critical health from a latched event log with no fault text behind it, NVMe drives, drives in pass-through mode, and machines advertising 39 telemetry reports.

What it has not been tested against

  • iDRAC 7 and 8, and non-Dell Redfish. Untested rather than known broken. The plugin discovers what a server offers instead of assuming it, so a missing endpoint should cost you that one subsystem rather than the whole poll.

If you have one, a report saying it worked is as useful as one saying it did not.

Requirements recap

  • Dell PowerEdge with an iDRAC that speaks Redfish, built for iDRAC 9 and 10.
  • Domoticz with the Python plugin system enabled, Python 3.11 or newer.
  • Standard library only. No third-party runtime dependencies.
  • The coloured bar graphs additionally need a Domoticz build from 19 August 2026 or later. Everything else works on any Domoticz with plugin support.

Contributing

Issues and pull requests are welcome at Rouzax/dell-idrac-domoticz-plugin.

The test suite runs without any hardware, against recorded Redfish payloads:

pip install -r requirements-dev.txt
python3 -m pytest

Before opening a pull request, please also run:

ruff check . && ruff format --check .
pyright

If you have a PowerEdge model that is not covered, a sanitized payload capture is genuinely useful. Two of the bugs listed above came from exactly that. See tools/capture_fixtures.py, and read the sanitization test first: captures must be scrubbed before they go anywhere near a commit.
