Remote meter reading

Read every meter in your buildings without a site visit

Energy-billing companies and heat utilities need the readings of every flat, and each reading on site costs a visit. CHESTER wM-Bus stays in the building, hears the meters already installed and sends their readings over LTE-M or NB-IoT.

Book meeting See how it works

1 January 2027

From this date, meters and heat cost allocators that cannot be read remotely must be adapted or replaced (EU Directive 2018/2002, Article 9c).

Remote reading without new wiring

The EU Energy Efficiency Directive sets the date. CHESTER wM-Bus reads the T1 and C1 wireless M-Bus meters a building already has, with no new cables.

ENEROOO

ENEROOO turns the readings into costs per flat

ENEROOO ENEROOO

ENEROOO is our energy management software for apartment buildings. ENEROOO s.r.o. sells it in Czechia under its own brand.

  • Every flat measured

    Electricity, water and heat are measured flat by flat, so each household pays for its actual use.

  • A portal for the building

    Every resident sees their own consumption in real time, and the building’s managers export it for billing.

  • Rooftop solar shared

    One grid connection can serve the whole building, and the ENEROOO Box sends solar surplus to water heaters.
