A BLE Mesh retrofit lets a hotel add full room control without pulling a single new cable. The work is planned at a desk and executed room by room with almost no guest disruption. This playbook walks through the six steps Guangzhou Hotekey Electronics Co., Ltd. uses to take a property from survey to signed-off smart rooms.
Survey: room matrix, power points and coverage
The first step is a room matrix: how many room types, which loads each room carries such as lighting circuits, HVAC, curtains and DND/MUR, and where the existing distribution points sit. At the same time a coverage walk confirms BLE Mesh reaches every corner, because a wireless mesh is only as good as its weakest link. HOTEKEY's site template records panel positions, switch boxes and signal obstructions so the plan is built once, not discovered on the ladder.
Network design: gateway placement and node count
BLE Mesh is a self-healing flood network, so gateway placement decides how many hops a message travels. The rule of thumb is one gateway per floor or per service zone, with enough nodes that every device has at least two neighbours. Design also fixes the group-address map before anyone pairs a device, so scenes and linkage are reproducible across identical rooms instead of hand-tuned one by one.
Commissioning: binding gateways, joining nodes, group addresses
On site, each panel and actuator is joined to its gateway and assigned to the planned group addresses. Because BLE Mesh needs no dedicated commissioning dongle, a phone or tablet is enough to bind nodes, which keeps the installer team small. HOTEKEY's BLE Mesh hardware ships pre-labelled by room, so joining is a scan-and-assign task rather than a wiring diagram exercise.
Scene and linkage mapping
With nodes on the bus, scenes are mapped: welcome, sleep, away and cleaning, plus door-card and occupancy linkage. The same group address that drives lighting also drives curtains and HVAC, so one scene sets the whole room. This is where the room starts behaving as a system rather than a bag of switches, and most of the value shows up here.
PMS and GRMS linking
The final in-room step connects the floor to the property. HOTEKEY's GRMS exposes open room-status interfaces over TCP/IP, so check-in, check-out and housekeeping states flow to and from the PMS without custom middleware. Once linked, an empty room shifts to its energy profile automatically instead of waiting for a manual switch.
Acceptance: per-room sign-off
Handover is a per-room checklist: every scene fires, every load responds, and the panel reports correctly to the dashboard. Sign-off by room type, not by building, catches the one mis-addressed node before it becomes a complaint. A documented acceptance sheet is also what protects the installer if a room is later reconfigured by someone else.
Frequently asked questions
- Will installation disturb guests?
- No. BLE Mesh is wireless, so work inside the room is limited to swapping in wireless panels and actuators. There is no wall chasing or rewiring, and most rooms are back in service the same day, which is why it suits operating hotels.
- How long does it take?
- A standard floor typically takes one to two days; a full property scales with room count and whether PMS integration is done in the same visit. Phased floor-by-floor rollout keeps part of the hotel always open.
