# Frequently Asked Questions

Find answers to the most common questions about the Voldeno smart home system. Topics below mirror what we highlight for homeowners and installers & integrators; for wiring limits, always follow Bus topology & wiring.

# General

# What is Voldeno?

Voldeno is a professional-grade smart home and building automation system built for reliability and flexibility. It uses modular DIN-rail hardware on the Voldeno Bus (CAN-FD), with distributed logic on modules where possible. The HUB provides Ethernet, local storage, and integration to IP networks and tools—it is a gateway, not a classic single central controller whose failure must stop the entire installation.

# Do I need internet for Voldeno to work?

No. Voldeno operates entirely locally. Automations, scenes, and controls keep working without internet. Internet is only needed for remote access from outside the home (e.g. Voldeno Mobile), when you choose to use it.

# Can I install Voldeno myself?

DIY is possible in principle, but we recommend professional installation for safety, compliance, and warranty—especially for mains-voltage wiring. Voldeno field wiring is documented so that any qualified electrician can install the bus; we can also connect you with a certified Voldeno installer and support remote configuration where appropriate.

# Homeowners

# Is Voldeno suitable for an existing house or only new builds?

Voldeno is a wired system—it fits best in new builds where cabling is part of the electrical design. In existing buildings, installation is realistic during major renovations when rewiring is already planned. For lighter scenarios, a single HUB can integrate other equipment over HTTP/TCP without extra Voldeno bus wiring.

# What if my electrician doesn't know Voldeno?

Voldeno wiring does not require specialist knowledge beyond standard electrical practice—it is covered in our technical documentation. A qualified electrician can install it using the docs. We can also put you in touch with a certified Voldeno installer in your area, and we can handle system configuration remotely.

# Can I control my home without the app?

Yes. Standard momentary (bell-type) wall switches—the kind sold at any electrical supplier—are enough for everyday control. The app adds convenience; it is not required for the system to work.

# What happens if the internet goes down?

Nothing critical changes locally. Processing stays on-site; automations, scenes, and controls continue. You only lose remote access from outside the home until connectivity returns.

# How much does a typical installation cost?

It depends on size and scope. A modest starter system for a few rooms is possible, and you can expand later. Our projects pages list module counts per installation—a useful benchmark. Contact us for a tailored quote.

# Can I start small and expand later?

Yes—that is a core principle. Buy what you need now, add modules anytime, without replacing existing hardware to grow.

# Installers & partners

# How long does training take?

Basic certification can be completed in one day. Advanced Volang training adds roughly another day. Both are offered online and in-person.

# What margins can I expect on hardware?

Partner margins are competitive and scale with volume. Contact us for the partner price list and program details.

# Do I need to stock inventory?

No. You can order per project. For active partners we also support consignment programs for faster turnaround.

# How does remote support work?

Voldeno Cloud supports remote configuration and diagnostics so you can troubleshoot and update client sites without an on-site visit when the installation allows it.

# What if a module fails on-site?

Modules are hot-swappable. Replace the faulty unit; the system auto-configures the replacement—no full reprogramming of the installation from scratch.

# How is Voldeno different from other systems?

Many systems use RS-485—a simple bus without built-in error handling comparable to CAN. Voldeno Bus uses CAN-FD: hardware arbitration, error detection, and automatic fault isolation, with higher throughput and 64-byte frames. The architecture aims at no single point of failure, new logic without firmware updates for each change, and the Volang automation language for advanced cases.

# Hardware

# What's the maximum number of modules on the bus?

A single linear Voldeno Bus segment supports up to 40 modules. Total bus length is up to 300 meters along the chain; stub length off the main line must stay within documented limits (1 meter max for defined stubs). See Bus topology & wiring. Larger sites use additional segments and/or multiple HUBs according to project design.

# How long can the bus cable be?

Up to 300 meters total along the communication bus from first to last module on that segment, per the bus topology specification. Power distribution has separate voltage-drop constraints—verify levels at module terminals.

# Are the modules DIN rail mounted?

Yes. All Voldeno modules are designed for standard 35 mm DIN rail mounting.

# Software

# How do I update the firmware?

Firmware updates are performed through Voldeno Studio:

  1. Connect to your HUB
  2. Go to Tools > Firmware Update
  3. The system checks for and applies available updates

# Can I program custom automations?

Yes. Two main paths:

  • Logic Blocks — visual drag-and-drop in Studio
  • Volang — full language for advanced logic

# Is there a mobile app?

Yes. Voldeno Mobile is available for iOS and Android for everyday control, scenes, notifications, and energy views when remote access is enabled.

# Integrations & connectivity

# What protocols and interfaces does Voldeno support?

Besides Voldeno Bus (CAN-FD) between DIN-rail modules, professional installations commonly use:

InterfaceTypical use
HTTPIP-based integrations and services
TCPAlarm systems and similar session-oriented links
UDPIoT-style devices
ModbusField and building integrations
1-WireThermometers and 1-Wire sensors
0–10 VAnalog control
4–20 mAIndustrial sensors

What is available on a given job depends on which modules are installed and how they are configured in Voldeno Studio. Wiring and module-specific topics (bus topology, 1-Wire, analog inputs, Modbus, and similar) are covered elsewhere in this documentation.

# Support

# Where can I get help?

# What's the warranty period?

All Voldeno modules are covered by a 3-year manufacturer warranty.
