Wireless BLE series adopts mature Bluetooth BLE technology, with advantages such as easy installation, no wiring, and simple maintenance
Wireless BLE series adopts mature Bluetooth BLE technology, with advantages such as easy installation, no wiring, and simple maintenance, especially suitable for intelligent transformation of hotels and other places.
Wireless BLE series is widely used in various scenarios
Intelligent control of lighting, air conditioning, curtains, etc. in hotel rooms, improving guest experience.
Wireless control of home appliances, lighting, security systems, etc., creating a smart living environment.
Intelligent control of office lighting, air conditioning, access control, etc., improving energy efficiency.
Hotekey supplies both. The right answer depends on whether the building already has bus wiring and who signs off the specification.
| Decision factor | Bluetooth Mesh (J26 series) | KNX (twisted-pair bus) |
|---|---|---|
| Best fit | Renovation, boutique hotels, B&B and mid-tier properties | New-build luxury hotels where KNX is specified by the owner or consultant |
| Control wiring | None. Devices replace the existing switch and re-use the lighting circuit | KNX bus cable required throughout the guest room |
| Commissioning | App-based room template push, no ETS licence needed | ETS6 project file, per-device group addressing, certified integrator |
| Network size | Up to 200 nodes per self-organising mesh | 64 devices per line, extended by line couplers |
| Retrofit disruption | Room stays in service — typically 8–10 rooms per day per crew | Requires opening walls or conduits for the bus |
| Reliability model | Multi-node relaying, one gateway per room, offline scene linkage if the cloud drops | Deterministic bus with decades of multi-vendor interoperability |
| Cost profile | Lower material and labour cost per room | Higher device and engineering cost, higher resale standard |
| Choose it when | The hotel is occupied or the budget is fixed and the deadline is tight | The specification already mandates KNX, or the project is a flagship new build |
Still undecided? Many projects run a hybrid: Bluetooth Mesh in the renovated wing and KNX in the new tower, with both reporting into the same PMS. Hotekey ships both protocols, so the gateway, room templates and after-sales contact stay the same — you are not managing two vendors. Tell us the building year, room count and who signs the spec, and we will tell you which one we would put in.
