Some enclosures (Xyratex/NetApp shelves) leave SES element descriptor
strings blank; sg_ses prints the literal '<empty>'. Skip it so temp
sensors fall back to a generic 'Temp N' label instead of '<empty>'.
- enclosure: fetch SES element descriptor page (0x07) and label temp/fan/
psu/voltage elements with human-readable names
- temps service + /api/temps: per-enclosure hotspot (max across SES sensors
and housed drive temps) plus named SES sensor list
- mqtt_publisher: paho-mqtt with HA discovery (device per enclosure, hotspot
+ per-sensor entities), LWT availability, opt-in via MQTT_HOST
- secrets: OpenBao KV v2 reader; MQTT creds sourced from secret/home_assistant
with env fallback
- compose/requirements/README updated
Xyratex HB-1235 enclosures have non-functional temperature sensor
slots that report Unrecoverable/Unknown at 0°C. The SES header
rolls these into UNRECOV=1, causing a false CRITICAL flag. Now we
skip dead sensors (0°C + non-OK status) and derive overall_status
from the actual parsed elements instead of the raw header counts.
Dual-IOM shelves (e.g. NetApp DS2246 with two IOM6 modules) create
two sysfs enclosure entries. The secondary path reports populated
slots via SES but the kernel only links block devices through the
primary path. Filter these out during discovery to avoid showing
ghost enclosures with no drive data.
Parse sg_ses --page=0x02 output to surface enclosure-level health data
including power supply status, fan RPMs, temperature sensors, and voltage
rails. Failed/critical components are reflected in the overview totals
and shown as status pills in the enclosure card header with an expandable
detail panel.
