@@ -10,6 +10,11 @@ pre-releases for test devices only.
   - *Current printers and multifunction devices* that speak IPP over USB (most since about 2015, e.g. HP Smart Tank, OfficeJet, Canon PIXMA, Epson EcoTank) print **without a driver**: Windows 10/11, macOS, iPhone/iPad and Android find them by themselves (IPP Everywhere, AirPrint, Mopria) – and their **scanner** works over the network as well (eSCL). ipp-usb (OpenPrinting) does the work; ShareOS's avahi-daemon has no D-Bus, so a patch makes ipp-usb announce the devices through static avahi service files. The port of each device stays the same (kept on the flash).
   - *Older printers* (usblp, `/dev/usb/lpN`): p910nd on port 9100 + N, announced as `_pdl-datastream`; the computer uses the maker's driver ("Standard TCP/IP port" in Windows, AppSocket/JetDirect). *Testseite* sends a plain-text/PCL page.
   - Printers are followed when plugged in or pulled (mdev rule for `lp*`, ipp-usb watches USB itself). Mode *Immer Port 9100* for printers whose driverless printing misbehaves. `shareos-printer`, rpcd `shareos.printer`, `tests/test-printer.sh` (14 checks with a fake /sys).
+- **UPS over USB** (Dienste → USV, new system app **"nut"** in the store: Network UPS Tools 2.8.5 with the drivers usbhid-ups, nutdrv_qx and blazer_usb – APC, Eaton, CyberPower, most Megatec/Q1 boxes; 0.7 MB, kept on the flash so it works when a disk fails).
+  - Charge, runtime, load and model of the UPS; a power failure, the power coming back, a low or worn battery and a lost connection become messages (e-mail/push as set up) and are listed under *Ereignisse*.
+  - The box shuts down cleanly while on battery – when the UPS reports a low battery, below a charge of your choice or after some minutes on battery – and only then; if the power comes back first, nothing happens. Afterwards the UPS switches its output off and on again when the power is back, so the box starts by itself (can be switched off).
+  - Other computers can read the UPS over the network (NUT, port 3493, user `monitor` with a password) and shut down before the box.
+  - NUT without OpenSSL (`external.mk`: 4.4 MB of libraries less). `shareos-ups`, rpcd `shareos.ups`, the last step of the shutdown in `S05board`, `tests/test-ups.sh` (20 checks with fake NUT programs).
 - **DynDNS, own certificate authority and Let's Encrypt** (System → Netzwerk).
   - *DynDNS*: DuckDNS, dynv6, Cloudflare, No-IP or any dyndns2 address (Strato, IONOS, …), IPv4 and/or IPv6 (for lines without their own IPv4 address: DS-Lite, fibre, mobile). The box reports its public address every 5 minutes when it changed, otherwise once a day; a failure becomes a message. Token and password go to curl through stdin, not the command line, and are never sent back to the browser. `shareos-ddns`, `tests/test-ddns.sh` (24 checks with a fake curl).
   - *Own CA*: a certificate authority on the box (EC P-256, 10 years) issues certificates for the box and other devices in the home network (825 days, server authentication, wildcards like `*.home.lan`, IP addresses); its root certificate is installed once on PCs and phones, after that there are no certificate warnings. The box's own certificate follows name and IP address and is renewed 30 days before it runs out. The CA is part of the settings backup. `shareos-ca` (mbedtls of the firmware), `tests/test-ca.sh` (18 checks, in CI with the firmware's programs in qemu).

 - Never `rm -rf` a chroot that still has mounts below it (it would delete the host's /dev).
 - Apps live in the separate repository UniqueDroid/ShareOS-Apps.
 - New UI texts: add them to `i18n/en.json` and to every `tools/i18n/<code>.tsv` (new numbers at the end), then `tools/i18n/build-lang.py`; `tests/check-i18n.py` must pass.
