Manual reading visits are your real cost
Based on a conservative estimate of €25 per site visit for technician time, travel, and admin, typical for Central European deployments. Western European costs are typically €40–60.
Hardware is a one-time cost. Reading visits are eliminated permanently. Year 2+ saving equals the full annual visit cost.
Built for these situations
Connect 1–3 heat meters per station without wiring new power. The most common ACRIOS use case.
Outdoor installations at building entry points. IP67 protection and battery operation included.
Meters that already exist but are without wireless communication. Keep them, just add ACRIOS converter.
No power socket nearby? The converter powers the entire M-Bus line from its own battery.
ACRIOS is perfect for small installations of 1–5 meters. We do support 16UL, but mainly for versatility and to support MBus bridges such as wM-Bus to M-Bus. For sites with dozens of meters on a single line, such as apartment building, a dedicated M-Bus concentrator with external power supply and internet connection may be a better fit for you.
Every detail counts in the field
Built for harsh environments
- IP67 rated – fully waterproof and dustproof; suitable for outdoor cabinets, basements, and heat stations
- SMA antenna port – standard connector; extend outside a metal cabinet for full signal when needed
- WAGO terminal block – tool-free snap wiring, no loose screws, zero installation mistakes
- Captive lid screws – screws stay attached; IP67 seal stays intact during every service visit
Single battery for up to 10 years
- EVE ER34615M D-Cell (19 Ah) – primary lithium, −40 °C to +85 °C rated, no self-discharge concerns
- 3.6 – 3.8 years at SF7, 15-min interval, verified in real deployments
- Over 10 years battery life at 1-hour interval, ideal for billing-grade metering
- User-replaceable without tools
- Sourced from distributors across Europe, no ACRIOS dependency
Dual battery for up to 20 years
- FANSO ER34615 dual pack (38 Ah) – double capacity in the same enclosure footprint
- 7.1 – 7.5 years at SF7, 15-min interval – cuts maintenance visits in half vs. single cell
- Over 20 years battery life at 1-hour interval – set it and forget it
- Drop-in swap – same enclosure, plug-in pack; field replacement takes under two minutes
Set up in minutes, not hours
Configuration used to require writing Lua scripts. Now a step-by-step web Wizard handles it: scan, select, send.
Connect & scan
The wizard automatically discovers all connected M-Bus meters: names, IDs, and meter types. No manual addressing needed.
Pick your data
Choose exactly which values to transmit (energy, volume, temperature…) with a live byte count. Know exactly what will be sent before sending it.
Set interval & push remotely
Save the configuration to the device. You can later change or modify the configuration via downlinks.
Why installers choose ACRIOS
The converter powers the entire M-Bus line from its own battery. No 230V installation, no inspection, no extra cost.
Many meters lack a LoRaWAN module, mainly older or mixed-brand ones. ACRIOS works on the M-Bus line itself, so manufacturer is irrelevant. 30+ models tested, no vendor lock-in.
Easy remote configiration. Change meter reading intervals, add meters, or update addressing via LoRaWAN downlink, without a site visit.
Designed and produced in the Czech Republic. Full firmware control, Cyber Resilience Act ready, long-term support guaranteed.
The obvious alternative often doesn't exist
Adding a LoRaWAN radio module directly to each meter sounds simple. But for most meters in the field, that module simply isn't available.
Per-meter LoRaWAN module
- Only available for select models from a handful of major manufacturers, most older and mid-tier meters have no module option at all
- Vendor lock-in: Kamstrup's module works on Kamstrup meters only. Mixed-brand sites require multiple vendors, contracts, and firmware tracks
- Cost multiplies per meter: €80–150 per device, installed individually, regardless of how many meters share the same location
- Retrofit impossible for legacy meters: meters installed 5–15 years ago rarely have a current wireless module option from the original manufacturer

ACRIOS M-Bus converter
- Works with any M-Bus meter from any manufacturer: the protocol, not the brand, is what matters. 30+ models verified.
- One device, multiple meters: connect up to 16 meters from different manufacturers on a single M-Bus line, one converter
- From €10 per connected meter at full capacity, cost per meter is a fraction of any per-meter radio module
- Full retrofit support: if the meter speaks M-Bus, it works. Age and manufacturer do not matter.
For meters that speak wM-Bus or Modbus, ACRIOS makes converters for those protocols too. Ask us if your site has mixed meter types.

Plug into your existing platform. No middleware required.
The converter sends standard M-Bus frames over LoRaWAN, and system that speaks M-Bus can receive them directly. No ACRIOS software required. Optional management platform available if you needit.
Direct integration into your platform
Connect the converter straight to your existing BMS, SCADA, or IoT platform. The device transmits standard M-Bus frames. Any system that speaks M-Bus can receive and parse them, no middleware needed.
- Standard M-Bus frame format, decode with any library
- Compatible with Lobaro, Elvaco parsers and other
- No license, no lock-in, no ongoing fees
- Push to your MQTT broker, REST endpoint, or LoRaWAN server
- Works with The Things Stack, ChirpStack, Akenza, and an LoRaWAN NS
ACRIOS Platform
If you don't have a platform yet, or need a dedicated metering management layer, ACRIOS offers a hosted web platform for device management, group allocation, and data export.
- Hosted by ACRIOS or deployed on your servers
- Group & unit management with CSV export
- REST API for custom integrations (OAS3)
- Used in production across water utilities and building operators
Works with any LoRaWAN network
Wired M‑Bus to LoRaWAN concentrator sends standard LoRaWAN Class A packets. Any compliant network server can receive and forward them. Step-by-step integration guides are available for The Things Stack and Akenza.io.
Trusted by teams across Europe
The solution is quick to install, requires no training and proves to be stable over time. We offer the ACRIOS remote reading solutions to all of our customers who want to comply with the EED decree.
DEPLOYMENT
We successfully integrated the ACRIOS converter in our smart metering project, seamlessly connectin hundreds of meters. Performance and stability have been outstanding, even in challenging environments.
We were searching for a way to connect existing M-Bus meters to our LoRaWAN network and found the solution provided by ACRIOS valuable for exactly these use cases.

Frequently asked questions
Everything a first-time buyer typically wants to know. If your question isn't here, ask us directly.
Yes. The converter communicates over the LoRaWAN network, so you need either your own LoRaWAN gateway or existing public LoRaWAN coverage at the installation site.
You can install a private LoRaWAN gateway or use an external antenna to improve signal quality. The converter is suitable for both public and private LoRaWAN deployments.
The converter supports standard wired M-Bus meters compliant with EN 13757, including heat, water, electricity and gas meters from many manufacturers.
Yes. Sample units are available for testing, pilot projects and integration validation before larger deployments.
No dedicated software is required. The converter transmits standard M-Bus data via LoRaWAN and can integrate with compatible LoRaWAN platforms, parsers and cloud systems.
Battery life depends on transmission frequency, connected meters and network conditions, but battery-powered variants are designed for multi-year operation.
The converter can be remotely reconfigured over LoRaWAN. Meter settings, addresses and communication parameters can be updated without visiting the installation site.
Everything you need to integrate
Scan meters, select data, set intervals. No scripting required.
Integration manuals, protocol specs, installation guides, video tutorials.
Online frame decoder. Paste raw bytes, get parsed values instantly.
