 - **[HA]** Local add-on **smartmon v1.0.4** (`/addons/smartmon/`, alpine+smartmontools): loops `smartctl -d sat -s on -H -A -i -j /dev/sda > /share/smart.json` every 5 min; `full_access: true` + `apparmor: false` required (Supervisor bind-mounts /dev but adds no device cgroup rule for block devices — `devices:` list alone gives EPERM). SSD (Samsung MZMTD128HAFV, Lenovo OEM) shipped with SMART disabled → enabled via `-s on`. Baseline: health OK, 41°C, 36 544 POH, wear 92%.
 - **[HA]** Third dashboard **Floorplan** (`/floor-plan`, storage mode): Easy Floorplan card (HACS) with the full apartment plan — 21 walls, 9 doors, 5 windows, 12 colored room areas, 19 live entities (lights with glow, climate with state, Roborock, Bosch appliances). Config generated programmatically from the user's floor plan sketch and saved via `lovelace/config/save` (storage dashboards accept it; YAML ones don't).
 - **[HA]** Roborock live position on the Floorplan: template sensors polling `roborock.get_vacuum_current_position` (15 s) + Easy Floorplan tracker. Calibrated mm→plan from real-cleaning history (room centroids, least-squares; residuals ~0.5 m). Robot now visible as a pulsating marker on the apartment plan.
+- **[HA]** Calibration v3 via silent `set_vacuum_goto_position` tour + a user-directed master-bedroom run: 6 anchors across the apartment, mean residual ~0.7 m. Gotchas: goto mode spontaneously pauses mid-route (resume with a new goto or `vacuum.start`); `get_vacuum_current_position` often returns HTTP 500 while the robot is moving. Bedroom segments identified: 17=Teo, 22=master bedroom, 24=Dari — Prism popup room buttons relabeled.
 - **[NOTE]** Fan monitoring/control on HAOS is **impossible**: kernel 6.18.39-haos ships no Super I/O hwmon modules (nct6775/it87/…), no pwm nodes. BIOS-only.
 - **[NOTE]** Local add-on gotchas: no default `BUILD_FROM` (use explicit FROM), config changes need version bump + `/store/addons/<slug>/update`, failed rebuild deletes the image, transient DNS fixed with `ha dns restart`.
