Components

##Servers 2 X64 hosts 1x tiny with 1x zigbee adapter 1x PC with 1x GPU (rtx 3060 or better)

##Endpoints

#Living Room

1xMedia Station/TVPC (doesn't technically need to be in the same room) -> 1xThinClient (tiny is sufficient) 1xVoice Reciever - Round screen thingy 1xSound System (already have it, see #Have)

#Loggia

1xMiniscreen System (Lenovo all-in-one PC, large built-in touchscreen — already own it, free, see #Have) 1xSound System 1xVoice Reciever - Round screen thingy

#Linus Room

1xVoice Reciever - Round screen thingy 1xSound System ???

#Amirs Room

1xBeamer 1xThinClient (tiny is sufficient) 1xHA Voice PE 1xSound System

#Kitchen

1xTiny PC with Mini Touchscreen 1xCamera 1xVoice Reciever - Round screen thingy 1xSound System

##Lighting

~16x RGB smart bulb (exact count/room split TBD — see #Open items). Zigbee, not WiFi, to match this project's existing local-first Zigbee2MQTT backbone (already have the coordinator dongle) rather than adding a second, cloud-dependent lighting ecosystem. See #Need for the specific pick and why.

##Summed totals

#Servers 2x X64 host 1x Zigbee adapter 1x GPU (rtx 3060 or better)

#Endpoints (all rooms combined) 2x ThinClient (tiny) 1x Miniscreen System (Lenovo all-in-one, built-in touchscreen — already owned) 1x Beamer 4x Voice Reciever - round screen thingy (Living Room, Loggia, Linus Room, Kitchen) 1x HA Voice PE 5x Sound System (all confirmed: Living Room, Loggia, Linus Room, Amirs Room, Kitchen) 1x Tiny PC with Mini Touchscreen (Kitchen) 1x Camera (Kitchen)

#Lighting ~16x RGB smart bulb (Zigbee) — count/room split not finalized

#By room Living Room: 1x ThinClient, 1x Voice Reciever, 1x Sound System (have) Loggia: 1x Miniscreen System (have), 1x Sound System, 1x Voice Reciever Linus Room: 1x Voice Reciever, 1x Sound System, +1 unresolved (???) Amirs Room: 1x Beamer, 1x ThinClient, 1x HA Voice PE, 1x Sound System Kitchen: 1x Tiny PC w/ Touchscreen, 1x Camera, 1x Voice Reciever, 1x Sound System

#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

#Beamer (Amirs Room) — need 1

  • TMY 1080P Mini Portable Projector, HDMI/USB (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 (~€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
  • 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).

#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:

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 (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 (see link for price) — any UVC webcam works; picked for wide availability/driver support, not a specific requirement

#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 (also 2-pack) Yes Confirmed — zigbee2mqtt.io device page ~€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) 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
innr RB 285 C Zigbee RGB bulb ~16 (TBD) €15–20 €240–320

Subtotal (excludes the optional beamer mount): ~€1,729–2,020 Subtotal, including the optional beamer mount: ~€1,744–2,045

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.
