Our Services
Find faults faster
See offline luminaires, device faults, overheating, overcurrent-type faults and other supported alerts from connected lighting systems.
Maintain with precision
Turn vague lighting issues into targeted maintenance tasks. Know which luminaire or area needs attention before sending someone on site.
Support warranty reporting
Electrical contractors can use LumenGuard to document whether luminaires were online, offline or reporting faults during the warranty period.
Facility and property teams
Know when lighting problems appear across your sites and act before users start reporting dark areas. LumenGuard helps technical property teams move from reactive inspections to targeted maintenance.
Electrical contractors and maintenance providers
Offer lighting monitoring as an additional service after installation or use it internally to support warranty-period reporting. LumenGuard helps you verify whether faults existed, when they appeared and whether the system was healthy during a given period.
Lighting and electrical designers
Design lighting systems that remain transparent after handover. LumenGuard helps make connected lighting easier to maintain, easier to document and easier to support over its lifetime.
Affordable Pricing
Simple, per-system pricing: 34 € per lighting system a month, or 29 €/month billed annually. Each system needs a Casambi Cloud gateway on site — and if yours doesn't have one yet, you can choose to order it during registration.
How LumenGuard works
Connected buildings
Lighting failures are often discovered too late: when a tenant complains, a customer notices a dark area, or a technician has to inspect the site manually.
LumenGuard gives property teams, contractors and lighting professionals a simple way to see whether their lighting systems are alive, healthy and reporting faults.
You get a clear dashboard, fault alerts and a practical maintenance view — without building your own monitoring infrastructure.

However, bringing a lighting network fully online requires the correct credentials and setup steps. LumenGuard supports you during this process.
LumenGuard is built and operated by Sähköurakointi Voltti Oy — an electrical contractor that installs and maintains connected lighting every day. We built it because we needed it ourselves, and that field-first perspective is in every alert it raises.
A correct, verified alert with delivery confirmation beats a beautiful dashboard. LumenGuard focuses on real faults and useful maintenance — false alarms are treated as serious defects, so the alerts you get are ones you can act on.
LumenGuard observes and reports — it never controls or changes your lights. Monitoring only means it fits safely alongside your existing Casambi setup, adding visibility without touching how the system runs.
