+# nut — Network UPS Tools
+
+Monitors a UPS over USB (or serial/network), notifies via ntfy on power events
+and gracefully shuts the host down on low battery.
+
+## Supported distributions
+
+- Arch Linux
+- Debian/Ubuntu
+
+## What it does
+
+- Installs `nut` and configures it in **standalone** mode (single host, no
+  network slaves).
+- Configures the `usbhid-ups` driver against the UPS defined in `nut_ups_name`
+  (default: EATON Ellipse 1600, vendorid `0463`).
+- Binds `upsd` to `127.0.0.1:3493` only — no LAN exposure.
+- Runs `upsmon` as master, which:
+  - calls `SHUTDOWNCMD` (`systemctl poweroff`) on `LOWBATT`,
+  - dispatches every event to a `NOTIFYCMD` wrapper that POSTs to ntfy with
+    severity, tags and a host-aware title.
+
+## Configuration
+
+Variables — see [defaults/main.yml](defaults/main.yml).
+
+Required (role asserts at start):
+
+```yaml
+nut_monitor_password: "<min 12 chars>"  # local upsd user used by upsmon + exporter
+nut_ntfy_topic: "ups-<host>"
+```
+
+Optional but commonly tweaked:
+
+```yaml
+nut_ups_name: eaton
+nut_ups_description: "EATON Ellipse 1600"
+nut_ups_vendorid: "0463"
+nut_ntfy_server: https://ntfy.jokester.fr
+nut_ntfy_token: "tk_..."  # publish token for nut_ntfy_topic
+```
+
+## Operations
+
+### Check UPS status
+
+```bash
+upsc {{ nut_ups_name }}@localhost
+```
+
+### List configured UPSes
+
+```bash
+upsc -l
+```
+
+### Test the NOTIFYCMD pipeline without unplugging
+
+```bash
+sudo -u nut NOTIFYTYPE=ONBATT /usr/local/bin/ups-notify "Simulated ONBATT for ntfy plumbing test"
+```
+
+### Simulate a full power loss (DANGEROUS — actually powers off)
+
+```bash
+sudo upsmon -c fsd
+```
+
+### Logs
+
+```bash
+journalctl -u nut-monitor -u nut-server -u 'nut-driver@*' -f
+```
+
+## Security
+
+- `upsd` binds to `127.0.0.1` only.
+- `upsd.users` mode `0640` owned by `root:nut`.
+- No anonymous read access — exporter and upsmon both authenticate as
+  `nut_monitor_user`.
+- udev rules shipped by the `nut` package grant USB device access to the `nut`
+  group only.
+
+## Companion role
+
+See [`nut_exporter`](../nut_exporter/README.md) to expose Prometheus metrics
+based on the same upsd instance.

+# nut_exporter — Prometheus exporter for NUT
+
+Scrapes a local `upsd` and exposes UPS metrics for Prometheus.
+
+## Supported distributions
+
+- Arch Linux (AUR package `prometheus-nut-exporter`, installed via `paru`)
+
+Debian/Ubuntu is not packaged upstream — add it on demand.
+
+## Configuration
+
+See [defaults/main.yml](defaults/main.yml).
+
+Required:
+
+```yaml
+nut_exporter_nut_password: "<same as nut_monitor_password>"
+```
+
+Optional:
+
+```yaml
+nut_exporter_listen_address: "127.0.0.1:9199"
+nut_exporter_nut_server: "127.0.0.1:3493"
+nut_exporter_nut_user: monitor
+```
+
+## Pairing with Prometheus
+
+Typical scrape config (target uses the multi-target pattern: the exporter
+queries a remote upsd specified in the URL parameters):
+
+```yaml
+prometheus_scrape_configs:
+  - job_name: 'nut'
+    metrics_path: /nut
+    static_configs:
+      - targets: ['eaton@localhost']  # ups@host syntax
+    relabel_configs:
+      - source_labels: [__address__]
+        target_label: __param_target
+      - source_labels: [__param_target]
+        target_label: instance
+      - target_label: __address__
+        replacement: 127.0.0.1:9199
+```
+
+## Operations
+
+```bash
+systemctl status prometheus-nut-exporter
+curl -s 'http://127.0.0.1:9199/nut?target=localhost&ups=eaton' | head
+journalctl -u prometheus-nut-exporter -f
+```
+
+## Dependencies
+
+Requires the [`nut`](../nut/README.md) role (or any other running upsd) on the
+same host.
