  1. 01

    Base station in the basement

    Wired to the plant room; the Wi-SUN backbone reaches every floor through concrete.

  2. 02

    Zone gateway per floor

    Runs the control loop for its apartments locally — set up in about 15 minutes.

  3. 03

    Clip-on radiator actuators

    Replace the old valve heads; each room heats to its own setpoint and schedule.

  4. 04

    Room sensors

    Temperature and humidity in every room; CO₂ and presence where needed.

  5. 05

    Lighting without new cables

    Matter lights, wall switches and presence and lux sensors join the same wireless system: scenes per room, stairs and corridors on presence, and light that dims with daylight — nothing chased into the walls.

  6. 06

    Wireless meters

    Heat, water and electricity per apartment over wireless M-Bus — the 2027 EED rules met.

  7. 07

    About 30 minutes per apartment

    Nothing drilled, nothing opened; residents stay at home.

For the syndic and the co-owners

A proposal the general assembly can vote on

01

Clear scope and budget

After a radio survey: devices per apartment and common area, budget per lot, timeline — ready for the AG agenda.

02

Fair heating bills

Consumption measured per apartment, monthly information to every household, billing-ready exports for the syndic.

03

Fewer emergencies

Leak, window and heating alarms name the apartment; stuck valves are found remotely.

04

EV charging for the garage

With AMP X VOLT, charging for co-owners with load management on the building's existing connection.

Estimate

What room-level control could save in your building

Two inputs, three scenarios. Indicative, based on the cited studies.

What room-level automation saves in an apartment building

  1. Room-level control

    ~10% · Cholewa et al. 2017

    €4,400

    per year · €9 per apartment per month

  2. Room control plus hydronic balancing

    ~21% · Same study

    €9,240

    per year · €19 per apartment per month

  3. Full Bisly stack

    Range 20–35% · Bisly portfolio

    €8,800–15,400

    per year · €18–32 per apartment per month

Indicative. Savings are taken from the cited studies and Bisly references, not guaranteed. We calculate your building from its real consumption.

Social and affordable housing

For housing providers with many buildings

The same package in every building, managed with one login and ranked by energy and indoor air — the fastest payback in the portfolio.

Affordable and social housing

  1. Smart radiator thermostat on its own

    EDF / Vestemi, Radbot Smart TRV, Ofgem 2022

    ~3%

  2. Room-level control across the building

    Cholewa, Siuta-Olcha & Balaras, Energy and Buildings 151, 2017

    ~10%

  3. Room control plus hydronic balancing

    Same study, same buildings

    ~21%

  4. Plus forecast-based plant control

    A further 11–13%: Cholewa et al., Energy and Buildings 292, 2023

    +11–13%

  5. Full Bisly stack, 30+ schools and public buildings

Ask your AI assistant

What syndics and co-owners ask

“How can a copropriété in Luxembourg get remote-readable heat meters before 2027?”

The Energy Efficiency Directive requires remotely readable heat meters and heat cost allocators by 1 January 2027. With Bisly Wireless, AMP X SYNC installs wireless M-Bus meters and room-level control per apartment without new cables, in about 30 minutes per apartment, and provides monthly consumption information and billing exports.

“Do residents have to leave their apartments during the retrofit?”

No. The devices clip on or mount without drilling; installation takes about 30 minutes per apartment and residents stay at home.

“Can EV charging be added to the same building?”

Yes. AMP X VOLT, AMP X SYNC's sister brand, adds EV charging with dynamic load management on the building's existing connection, on the same platform.
