Remote meter reading

Read the wireless meters of every building you bill

CHESTER wM-Bus listens to the heat, water, gas and electricity meters of a building over wireless M-Bus and sends what they report over NB-IoT or LTE-M. Energy-billing companies and heat utilities install it in the buildings they bill.

Book meeting See CHESTER wM-Bus

1 January 2027

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

A reader in every building

The EU Energy Efficiency Directive sets the date. CHESTER wM-Bus reads the wireless meters already installed in a building, with no new wiring and nobody on site on reading day.

How it works

From the meter to your billing system

  1. 01 Meters Wireless M-Bus T1 or C1, of any manufacturer
  2. 02 CHESTER wM-Bus HARDWARIO 7+ years on batteries at a daily readout
  3. 03 HARDWARIO Cloud HARDWARIO Gets the telegrams over NB-IoT or LTE-M
  4. 04 Your billing system Takes them over the REST API and decodes them
