have the coordinator dongle) rather than adding a second, cloud-dependent lighting
ecosystem. See #Need for the specific pick and why.

#Open items
- Linus Room's "???" line is still undecided.
- Bulb count/room split is a guess ("like 16") — not yet mapped to specific rooms
  or fixture counts per room.

#Have
1xSound System (earmarked for Living Room)
Near infinite Tiny Pcs
near infinite ATX Pcs
1xHA Voice PE
1xZigbee adapter
1xLenovo all-in-one PC, large built-in touchscreen (Loggia's Miniscreen System — free, already have it)

##Need

Need = Summed totals minus Have. "Tiny Pcs"/"ATX Pcs" are covered (near-infinite
supply on hand), so ThinClients and the LLM-host chassis are NOT listed below —
only parts not already owned. Composite items ("Sound System", "Voice Reciever")
are broken into their actual sub-components, since "1x Sound System" isn't a single
SKU. Amazon links are real listings found via search (mostly amazon.com — search
only returned US results; check amazon.de for local pricing/shipping/VAT before
buying). No prices are invented below — where docs/project-plan.md already
documents one it's reused as-is, otherwise it says "see link."

#GPU (LLM host) — need 1
- Used RTX 3060 12GB (~€200–250, per docs/project-plan.md §1.2) — condition/model
  don't matter much, 12GB VRAM is the requirement (Q4 Qwen2.5-14B). New alternative:
  [MSI GeForce RTX 3060 Ventus 2X 12G OC](https://www.amazon.com/MSI-GeForce-Ventus-NVIDIA-Graphics/dp/B08WHJFYM8)

#Beamer (Amirs Room) — need 1
- [TMY 1080P Mini Portable Projector, HDMI/USB](https://www.amazon.com/TMY-Projector-Supported-Projection-Compatible/dp/B082F13J55)
  (see link for price) — budget pick; if the ThinClient output needs to look good on
  a big wall, a brighter/native-1080p unit is worth paying more for than a mini
  LED projector like this one
- HDMI cable, length depends on beamer placement vs. ThinClient — not sized yet
- Ceiling/shelf mount — only if not just resting on furniture

#Voice Reciever - round screen thingy (Living Room, Loggia, Linus Room, Kitchen) — need 4
This is `firmware/esp32-s3-touch-lcd-1.85c/` from this repo (Phase 14) — each unit
is a kit of:
- [Waveshare ESP32-S3-Touch-LCD-1.85C, round touch display dev board](https://www.amazon.com/waveshare-ESP32-S3-1-85inch-Touch-LCD/dp/B0DK6NH65T)
  (~€35–45 each per docs/project-plan.md §1.12) — **must be the V2 revision**, see
  `firmware/esp32-s3-touch-lcd-1.85c/README.md`; the listing needs checking for which
  hardware revision it actually ships, this repo's firmware assumes V2 (V1 has no AEC
  circuit and different audio pins)
- USB-C power adapter, one per unit — [5V/3A USB-C wall adapter](https://www.amazon.com/Security-01-Supply-Adapter-Type-C-MLF-C060503000CU/dp/B09JW4QQJ2)
- USB-C cable, one per unit (often included with the board — check the listing before
  buying separately)

4x board + 4x power adapter (+ cable if not bundled).

#RuView Presence Node (Living Room, Loggia, Linus Room, Amirs Room, Kitchen) — need 5
This is `firmware/ruview/` from this repo (Phase 2/§1.6) — anonymous room-level CSI
presence, still an unbuilt placeholder in this repo (no firmware written yet), but
the hardware spec is fixed regardless: a plain ESP32-**S3** board, no camera, no
extra peripherals — CSI presence reads WiFi channel state, not a camera. Separate
boards from the Bermuda BLE-proxy ESP32s (§1.5) — one chip runs one firmware.
- [Espressif ESP32-S3-DevKitC-1-N8R2](https://www.amazon.com/Espressif-ESP32-S3-DevKitC-1-N8R2-Development-Board/dp/B09D3S7T3M)
  (~€8–12 each per docs/project-plan.md §1.6) — the official board, minimal
  8MB-flash/2MB-PSRAM variant; RuView's own firmware has no published minimum spec
  yet (nothing's been written), so this is picked for being the plain, cheap,
  official option rather than a specific requirement.

5x boards, one per room.

#Sound System (all 5 rooms confirmed: Living Room, Loggia, Linus Room, Amirs Room, Kitchen) — need 4
Have 1 already (earmarked for Living Room), need 5 total, all confirmed → need 4 more.
Each unit is a kit of:
- [Fosi Audio V3 stereo amp (300W x2, TPA3255, w/ 48V PSU)](https://www.amazon.com/Fosi-Audio-V3-Amplifier-48V/dp/B0CGCSM191)
  (~€130 per docs/project-plan.md §1.13) — USB DAC/amp for the passive speakers below,
  same choice this repo's `hosts/audio-endpoint/` and `hosts/thin-client/` docs already
  make for amd64 rooms
- [Micca MB42X G2 passive bookshelf speakers, pair](https://www.amazon.com/Micca-Passive-Bookshelf-Speakers-Surround/dp/B0CGBKWBGM)
  (~€100/pair per docs/project-plan.md §1.13)
- [16-gauge speaker wire, 100ft spool](https://www.amazon.com/AmazonBasics-16-Gauge-Speaker-Wire-Feet/dp/B006LW0W5Y)
  (one spool easily covers multiple rooms — buy once, not once per Sound System)

1x spool of wire total; 4x (amp + speaker pair).

#Kitchen — need 1 touchscreen + 1 camera
`hosts/kitchen-display/` (Phase 17) — the Tiny PC is covered by "Have", these two
are not:
- [10.3" portable USB-C touchscreen monitor](https://www.amazon.com/Touchscreen-Stretched-Portable-Computer-Monitoring/dp/B0DFVZ2Z35)
  (see link for price) — needs to expose itself as a native Wayland `wl_touch`
  device, not just an emulated-mouse HID surface (unverified either way — see
  `hosts/kitchen-display/README.md`)
- [Logitech HD Pro Webcam C920](https://www.amazon.com/Logitech-Widescreen-Calling-Recording-Desktop/dp/B006JH8T3S)
  (see link for price) — any UVC webcam works; picked for wide availability/driver
  support, not a specific requirement

#Spare webcams — need 2
Destination not decided yet — going to whichever future camera-equipped clients need
one next (see docs/project-plan.md Phase 6/18: any camera-equipped endpoint can run
the identity registration flow, not just kitchen-display/door-panel).
- [Logitech C270 HD Webcam, 720p](https://www.amazon.com/Logitech-C270-Webcam-Megapixel-Interpolated/dp/B01IFBKK3W)
  (see link for price, typically the cheapest widely-stocked UVC webcam) — cheaper
  than the C920 above on purpose: these two are general-purpose spares, not tied to
  pantry-vision's food-photo use case that specifically wants the C920's autofocus,
  so there's no reason to pay for that here.

#Fixed BLE tags — need ~4 to start
For household members who don't (or shouldn't have to) carry a phone for presence to
work — a grandmother without a smartphone is the concrete case, but this is also just
generally the more reliable anchor `docs/project-plan.md` §1.5 already recommends over
a phone's own randomizing MAC. `identity/`'s registration flow supports registering
someone with **no** device at all (a manual home/away toggle instead), but a physical
tag is the better long-term answer once it's worth the ~€5–8 — see
`identity/README.md`'s "no device" section.
- [The Smart Anti Lost Tracker iTag-Tiny](https://www.amazon.com/iTag-Tiny-Innovative-Bluetooth-Anything-bidirectional/dp/B07FG7XJ9D)
  (see link for price, typically €3–8) — a plain Bluetooth 4.0 beacon with a
  replaceable coin-cell battery, not locked into Apple Find My/Google Find Hub's
  proprietary rotating-identifier scheme (most "key finder" listings on Amazon *are*
  locked to one of those and won't work here) — this is the generic style the HA/
  Bermuda community actually uses. **Verify before buying more than one**: cheap
  tags in this class often advertise a BLE *static random* address (technically
  "random" address-type, but stable for the tag's lifetime, unlike a phone's
  *resolvable private* address which deliberately rotates) — community reports say
  they "show as Random MAC but are stable," which is what actually matters for
  `identity`'s `TRUSTED_ENTITY_PREFIXES` allowlist, not the address-type label
  itself. Confirm one tag's address is genuinely stable (watch it in HA's Bluetooth
  debug log over a few hours) before buying a batch.
4x to start (one for the concrete grandmother case plus a few spares/guests); buy
more as more device-less household members come up.

#Lighting — need ~16 RGB smart bulbs (count TBD)
**Zigbee, not WiFi/cloud bulbs** — the whole point of the Zigbee2MQTT backbone this
project already runs (§1.3) is one local mesh instead of N different manufacturer
clouds; a WiFi bulb (Tuya/WiZ/etc.) would be a second, cloud-dependent ecosystem
bolted onto a stack that's explicitly local-first everywhere else. Mains-powered
Zigbee bulbs also act as mesh **routers**, which matters here specifically: ~16 of
them spread across every room does more for whole-house Zigbee coverage (for the
battery sensors in §1.4) than the coordinator alone ever could.

Three real options were compared, not just the first search hit:

| Option | Router? | Zigbee2MQTT support | Price | Verdict |
|---|---|---|---|---|
| [innr RB 285 C](https://www.amazon.de/Smart-dimmbar-kompatibel-Philips-RB/dp/B07GT1LWDH) (also [2-pack](https://www.amazon.co.uk/Innr-Colour-Philips-Assistant-Required/dp/B07GT12JTJ)) | Yes | Confirmed — [zigbee2mqtt.io device page](https://zigbee.blakadder.com/Innr_RB_285_C.html) | ~€15–20/bulb (docs/project-plan.md §1.4) | **Picked** — already this project's own documented choice, real listings on multiple Amazon EU sites, RGBW + tunable white 2200–6500K |
| IKEA TRÅDFRI color | Yes | Well-supported, huge install base | ~€12–15/bulb (cheapest of the three) | Not on Amazon in most regions (IKEA.com/stores only) — cheaper on paper but doesn't fit "find it on Amazon," and the color-capable SKU specifically (not the tunable-white-only ones) needs care to pick |
| Sengled Zigbee color (e.g. [2-pack](https://www.amazon.com/Sengled-Changing-Dimmable-Multicolor-Equivalent/dp/B0899LJHVV)) | **No** — end device only | Supported, but community reports of RGB/XY color quirks on some zigbee2mqtt versions | Similar ballpark to innr | Skipped — buying 16 non-router bulbs throws away the mesh-strengthening benefit that's the actual reason to prefer mains-powered bulbs here |

Buying at this quantity: check amazon.de for a 4-pack or larger multi-pack of the
RB 285 C (cheaper per-unit than 16x single-packs) before ordering singles.

4x-pack pricing wasn't found in search results — verify against the live listing.

#Open items carried over from above
- Linus Room's "???" line is still a completely open slot — nothing to shop for
  until it's decided what it is.
- Loggia's Lenovo all-in-one is already owned, so nothing to buy. `hosts/touch-panel/`
  now handles either way its touch panel shows up to Linux (native `wl_touch`, or an
  emulated-mouse HID device via the `type:pointer` fallback + a udev override to fix
  it properly — see that host's README "Touch input: two tiers"), so this is no
  longer a go/no-go check, just worth running once to know which tier it landed in
  and whether the override needs filling in for full multi-touch.
- Bulb count/room split — priced below at ~16, but that's a placeholder pending an
  actual per-room fixture count.

##Price estimate

Rough figures in EUR, for the #Need list above. **Estimates, not live-checked
prices** — the four docs/project-plan.md-sourced ones (GPU, ESP32 board, amp,
speakers) are reused from that doc as-is; everything else is a typical-market-price
guess for that exact product category, not pulled from the live Amazon listing (the
search used to find these links doesn't return price data — click through and check
before budgeting against this). All EUR figures assume roughly 1:1 with the USD
prices these products actually list at; check amazon.de directly for real
local pricing/VAT/shipping.

| Item | Qty | Est. unit price | Est. subtotal |
|---|---|---|---|
| Used RTX 3060 12GB | 1 | €200–250 | €200–250 |
| TMY 1080P mini projector | 1 | €40–65 | €40–65 |
| HDMI cable | 1 | €6–10 | €6–10 |
| Ceiling/shelf mount *(optional)* | 1 | €15–25 | €15–25 |
| Waveshare ESP32-S3-Touch-LCD-1.85C board | 4 | €35–45 | €140–180 |
| USB-C 5V/3A wall adapter | 4 | €7–12 | €28–48 |
| Fosi Audio V3 amp | 4 | €130 | €520 |
| Micca MB42X G2 speakers, pair | 4 | €100 | €400 |
| 16AWG speaker wire, 100ft spool *(one-time)* | 1 | €15–22 | €15–22 |
| 10.3" portable USB-C touchscreen monitor | 1 | €85–130 | €85–130 |
| Logitech HD Pro Webcam C920 | 1 | €55–75 | €55–75 |
| Logitech C270 spare webcam | 2 | €25–35 | €50–70 |
| innr RB 285 C Zigbee RGB bulb | ~16 (TBD) | €15–20 | €240–320 |
| iTag-Tiny fixed BLE tag | 4 | €3–8 | €12–32 |
| Espressif ESP32-S3-DevKitC-1-N8R2 (RuView) | 5 | €8–12 | €40–60 |

**Subtotal (excludes the optional beamer mount): ~€1,831–2,182**
**Subtotal, including the optional beamer mount: ~€1,846–2,207**

All 5 Sound Systems (Living Room, Loggia, Linus Room, Amirs Room, Kitchen) are
confirmed — see `#Open items` above — so all 4 needed amp+speaker kits are in the
main table above. The bulb line is the least certain figure in this whole table —
16 is a round-number placeholder, not a counted fixture list, so treat that
€240–320 as the roughest estimate here. Linus Room's still-blank "???" line isn't
priced at all — there's nothing to estimate until it's decided what it is.
