- Install from the Elgato Marketplace, or download the
.streamDeckPluginfrom Releases. - Turn on sharing in HWiNFO: Settings → Shared Memory Support.
- Drag HWiNFO Sensors → Sensor Reading onto a key and pick a reading.
Note
Needs Windows 10 or later (x64), Stream Deck 6.9+ and HWiNFO. Free HWiNFO switches Shared Memory off after 12 hours; if yours runs all day, I recommend HWiNFO Pro, which has no limit.
More: Getting started · Data sources
One reading with a sparkline, bar or ring, or up to four readings on one key.
- Press to cycle current, MIN, MAX and AVG.
- Labels size themselves to fit; decimals compact through k, M, G and T.
- Temperatures in °C or °F; bytes in decimal or binary units.
More: Sensor Reading
One reading or several on each Stream Deck + and + XL touchscreen segment, in any of the seven themes.
- View: one reading with a range bar, three compact rows, or two rows with big values and a trend line.
- At warn and critical the bar turns amber or red; the rest of the face keeps its theme.
- Rotate to move through the readings; the marked row follows and the list scrolls. Touch cycles stats; push resets the session.
- An HWiNFO Control key steers a dial from a pedal, a Multi Action or another deck.
More: Sensor Dial · Controls
Seven themes, set per key or once for the whole deck.
- At the warn threshold the key turns amber; at critical, red. Alert colors are the same on every theme.
- Alert when below flips the comparison for fan RPM or free space.
- Type accents (on by default) color the graph by sensor type; turn them off and each theme uses its own color.

A key press can open a full page of readings, then return.
- Show every reading from the pressed sensor, a list you build, or a filter such as
*gpu*fan*. - Pack up to four readings per tile and page through long sources.
- One editable profile ships per deck type, from Mini to + XL.

When a key can't show a reading, it names the problem and the fix.
What each screen means
| Key shows | Fix |
|---|---|
| Start HWiNFO | Start HWiNFO with Shared Memory Support or Gadget reporting on. |
| HWiNFO busy | Momentary; the plugin retries on the next poll. |
| Shared Memory off | Turn it back on in HWiNFO Settings (the free version's 12-hour timer lands here), or enable Gadget reporting. |
| Tick sensors in Gadget | In HWiNFO: Configure Sensors → HWiNFO Gadget, tick Report value in Gadget per reading. |
| Not updating | Reopen HWiNFO's Sensors window; restart HWiNFO if it repeats. |
| Access denied | Run HWiNFO and Stream Deck at the same privilege level. |
| Plugin damaged | Reinstall the plugin; an antivirus often quarantined bin/hwsm.node. |
| Pick a sensor / Sensor missing | Open the key's settings and pick the reading again. |
