Bisly Wirelesstaking orders now

full building control. no new cables.

The complete Bisly system for buildings that are already in use. Installed in days, floor by floor, while people keep working and living in the building. Only the plant room is wired.

The problem

Getting a cable to every room is a construction project

The control layer is missing

Heat pumps, ventilation, PV and meters get installed; the system that ties them together usually does not.

Cabled retrofits stop buildings

Risers opened, ceilings down, rooms out of use for weeks; months per building to design, cable and commission.

Renovation is now mandatory

The EPBD requires the worst 16% of non-residential stock renovated by 2030 and 26% by 2033.

Architecture

Three radios, each doing one job

Open standards end to end — no proprietary radio, no lock-in.

01Plant room, wired. The Bisly Server and integration modules connect substation, ventilation, heat pump, meters and DALI lighting over Modbus, BACnet, M-Bus and DALI-2.
02Backbone, Wi-SUN. Sub-GHz 868 MHz, frequency hopping, IPv6 self-healing mesh; hundreds of metres per hop through floors and concrete. The standard utilities use for smart meters.
03Zone, Thread and Matter. A local IPv6 mesh in each zone; the zone gateway runs the control loop. Matter is the device language backed by Apple, Google, Amazon and Samsung.
04Two speeds by design. Time-critical control stays in the zone; setpoints, schedules and readings travel over Wi-SUN. If the backbone is away, every room keeps its setpoint and schedule.

All zones connected

Devices

Everything in the zone is wireless, added by scanning its Matter code

Device	Radio	What it does
Base station	Wi-SUN, Ethernet	Mesh root in a riser or corridor, connected to the Bisly Server; one or more per building, meshed with each other
Zone gateway	Wi-SUN + Thread	One per floor, wing or tenancy (about 200 m²); runs the local control loop, schedules and buffering
Wireless actuator	Matter / Thread	Radiator, fan-coil and floor-heating valves; clips on in place of the old valve head
Room sensor	Matter / Thread	Temperature and humidity in every room; CO₂, presence and lux variants
Wireless meters	Wireless M-Bus	Heat, water and electricity per tenancy, read by the M-Bus gateway
Also	Matter	Room thermostat, wall switch, presence and lux sensor, integration module for plant controllers

Versus older wireless

Why Wi-SUN and Thread, not EnOcean, Zigbee or Bluetooth

	EnOcean	Zigbee	Bluetooth mesh	Bisly Wireless
Band	868 MHz, single channel	2.4 GHz, shared with Wi-Fi	2.4 GHz, shared with Wi-Fi and phones	Sub-GHz backbone, frequency hopping; Thread only inside the zone
Indoor range	About 30 m, no routing	10–15 m per hop	10–15 m per hop	Hundreds of metres per hop, through floors and concrete
When a link drops	The sensor is unheard	Reroutes if another router is in range	Flooding finds a path if relays are in range	Both meshes reroute; the room keeps its setpoint locally
Security	Application level	Shared network key	Shared keys	Certificate per device on the backbone, Matter attestation

Reliability and security

Built for the objection "wireless is unreliable"

Control runs in the room

Setpoints, schedules and the control loop live in the zone gateway; telemetry is buffered and forwarded.

The backbone carries very little

Kilobytes per zone per day — setpoints, schedules, alarms, readings. No video, no voice.

No single point of failure

Meshed gateways, meshed base stations and a wired plant island.

Secure by standard

802.1X / EAP-TLS certificate on every Wi-SUN node, Thread encryption, Matter device attestation, outbound HTTPS only.

Surveyed and accepted

Every site starts with an RF survey and ends with an acceptance report.

Where it fits

Three places wireless wins

01
Offices, new or in use
Wireless room control where cabling was never planned or the floor plan will change; phased floor by floor. References: Lāčplēša Plaza, Riga; Liivalaia, Tallinn (−30% energy).
02
Schools and public buildings
Installed during the school year; Matter lighting where no luminaire cabling exists; presence and daylight per classroom. Reference: Vanalinna Hariduskolleegium, Tallinn.
03
Apartment buildings and build-to-rent
About 30 minutes per apartment, nothing drilled, residents stay at home; billing by consumption on the same network.
Affordable housing

How it starts

Survey, pilot, roll out

RF survey

We walk the building and measure coverage. Scope and budget within 5 working days.

Pilot floor

One floor, riser or plant room installed and commissioned with the Installer App.

Building-wide

Zones and buildings added without construction. AMP X SYNC runs and services the building after handover.

Questions

Wireless questions

What is Bisly Wireless?

Bisly Wireless is the full Bisly building-automation system connected by radio instead of cables: a Wi-SUN sub-GHz backbone across the building and Matter over Thread inside each zone. It uses the same BMS, digital twin and apps as wired Bisly, and wired and wireless floors run as one system.

How long does an installation take?

About 30 minutes per apartment or zone for the devices; a zone gateway is set up in about 15 minutes. A building is typically done in days, floor by floor, while it stays in use.

What happens if the wireless backbone fails?

Each zone gateway runs its rooms locally, so every room keeps its setpoint and schedule. The plant keeps its last good plan, and readings are buffered and sent when the link returns.

Is Matter enough on its own for a building?

Matter standardises the device. A building also needs a fleet layer that commissions, schedules and monitors hundreds of devices next to the existing plant. Bisly Wireless is that layer.
