Existing stock: choosing the retrofit path matters more than device count
Serviced-apartment projects often add guest controlafter fit-out. PurePoint Smart offers wireless / light RS485 / hybrid hardware routes by wall-break level; full wiring comparison inStandard Guestroom Control · Engineering Reference. Remote room control and similar software are implemented by integrators or third-party platforms; PurePoint Smart supplies devices and wiring documentation.

* Per-room timeline is typical wireless retrofit range; same layout should clone BOM and wiring diagram versions—do not re-spec per unit.
Light per-unit · BOM comparison
Serviced apartments need not use full hotel six-point BOM—the table is theminimum set for ~80% of engineering asks, expandable against the standard guestroom master.

Retrofit paths · pick one
Serviced-apartment simplification aligned with hotel master wiring comparison—choose path, then BOM.
All wireless · MESH / Zigbee
Minimal wall changes, timeline in days; suited to short-stay high turnover and finished units. Core: gateway + wireless switches + lock + card power.
Engineering focus:minimal chase · low per-room BOM · same layout wiring clone
Light RS485
Local low-voltage closet + panel bus, more stable than all-wireless; suited to long-stay apartments, larger units.
Engineering focus:unified bus addresses · consistent module spare codes
Hybrid
Public wired + guest wireless, or card power/lock wired + lighting wireless; suited to multi-layout properties.
Engineering focus:phased stocking · later module expansion for circuits
Light documentation
Per-room wiring diagram + BOM template—electricians build to drawing; same layout clones SKUs, not redesign.
Light investment
BOM by room type—card power + lock + panel core trio, hardware cost estimable.
Per-unit delivery · four-step loop
Engineering rhythm from selection to acceptance—software integration optional fifth step by integrator.

Clone & go live
Same layout clones BOM and config—bulk stocking and delivery
Retrofit: full rebuild vs light hardware kit
Serviced-apartment pain point: "fit-out done, no more chasing." Light routes keep existing walls and furniture.
Traditional full rebuild
- Chase and rewire—long timeline, dust and noise affect operations
- Centralized RCU—higher per-unit investment
- Hard to extend—adding devices means more hard fit-out
PurePoint Smart light route
- Wireless switches / modules + gateway—minimal wall change
- Roll out room by room—prove one unit then clone
- Versioned BOM and wiring—same layout instant clone
- Optionalopen APIfor third-party hosting platforms
Three common layout templates
Same hardware base, different default BOM by segment—pick template at delivery to reduce per-unit disputes.
Short-stay / nightly
Code lock + card power + basic scene panel, delayed power-off after checkout—suited to OTA high turnover.
Card slot power →
Long-stay apartment
RS485 or wireless bus, door contact + low-standby modules—protocol integration by integrator.
Energy saving →
Themed / gaming
Multi-key scene panel + dimming module + relay, optional RGB strip.
Environmental control →Recommended minimum device kit
Serviced apartments need not use full catalog—the combo below covers ~80% of engineering asks; rest in cap-b and product pages.
