In development

Measure what your business consumes.

The Z series captures electricity, water, heat, gas and compressed air – per machine, hall or rental unit. Remotely read via M-Bus, Modbus and LoRaWAN, analysed in irot software, billing-ready thanks to MID.

The Z series is in development: pilot customers receive pre-series devices on special terms.

Zähler by irot: Z 100 three-phase DIN-rail meter with display and Modbus port

One family for every energy type.

Same housing, same protocols, same software – only the measuring core changes. The cabinet stays tidy and the analytics stay uniform.

Z 100 – electricity

Three-phase meter up to 100 A direct or via CT – MID-compliant for sub-metering and billing.

Z 200/300 – water & heat

Cold, hot water and heat meters with wireless readout – leak alarms included.

Z 500 – compressed air

The meter for the most expensive energy in the building: finds leaks and silent consumers in the network.

Z 700/800 – pieces & hours

Piece counters and hour meters turn machines into honest reporters.

Z 950 – gateway

Connects existing third-party meters via M-Bus and Modbus – your legacy becomes part of the system.

Analytics included

Every meter reports to irot software: load profiles, cost per cost centre, CO₂ balance – zero setup.

MID where it counts

Billing-grade measurement under the Measuring Instruments Directive – for subletting, charging points and contracting.

Data stays home

Readout locally, into your own data centre or into your irot cloud instance in Germany – your choice.

Installer-friendly

35 mm DIN rail, pluggable terminals, wiring diagrams in the lid – electricians love it.

From cabinet to chart

Mount

Meter onto the DIN rail, plug the terminals – or use CT clamps with no intervention at all.

Connect

M-Bus, Modbus or LoRaWAN – the gateway discovers every meter by itself and registers it in the software.

Analyse

Load profiles, comparisons and alarms in irot software – from day one, without a project.

Frequently asked questions

Can I use the meters to bill tenants?
Yes – that's what the MID version is for: conformity-assessed under the Measuring Instruments Directive and therefore billing-grade, for subletting, hall areas or charging points.
Do I need an electrician for installation?
For work inside the cabinet: yes, as always. The CT variants with clamps, however, need no intervention in the installation – clip on and done.
What about my existing meters?
The Z 950 gateway reads existing meters via M-Bus and Modbus. You see old and new meters in the same analytics – you only invest where nothing is measured yet.
Does the analytics work without the cloud?
Yes. Like all irot software it runs either in your dedicated cloud instance in Germany or entirely on-premises – then your readings never leave your site.
