Charger monitoring
Track charger and connector availability, fault status, charging sessions and site health from one supported platform.
Monitored. Supported. Ready.
PlugStream Sentinel
Managed EV charging support, monitoring and migration for commercial sites.
Keeping your charging estate visible, supported and ready.
PlugStream Sentinel is designed for workplaces, fleets, landlords and small commercial sites that need reliable EV charging without having to manage every charger, user, fault and configuration change themselves.
Whether you use PlugStream charge points or need help assessing an existing third-party OCPP estate, Sentinel gives you a practical support route without forcing immediate hardware replacement.
Assess first. Preserve where practical. Migrate where possible. Replace only where needed.
Service scope
What Sentinel helps with
Sentinel brings monitoring, support and practical management into one service, helping commercial sites stay in control of their EV charging estate.
Issue response
Log issues, triage faults, coordinate next steps and keep a clear record of what has been checked, actioned and resolved.
User and RFID management
Support users, groups, RFID access and charging permissions where the hardware and platform configuration allow it.
Third-party OCPP migration
Assess existing OCPP-compatible chargers and migrate them to PlugStream where practical, preserving working hardware where possible.
Reporting and visibility
Access session, energy and site-health reporting so commercial customers understand usage, issues and next actions.
Replacement planning
Where existing hardware is locked, unsupported or uneconomic to support, Sentinel helps plan staged replacement without unnecessary disruption.
Commercial sites
Built for commercial charging sites
Sentinel is suitable for organisations that already depend on EV charging and need a clear support route.

Process
How Sentinel works
Step 1
Assess
We capture the site, charger, connectivity and access details to understand what is installed and what support is practical.
Step 2
Onboard
Supported chargers are onboarded into the PlugStream platform, powered by AmpNexus, with site details, contacts and support preferences recorded.
Step 3
Monitor
We monitor charger status, sessions, issues and site health based on the Sentinel package selected.
Step 4
Support
Issues are triaged, recorded and moved forward through remote support, customer guidance, installer coordination or replacement planning where needed.
Operations
Support routes for installed charging estates
Sentinel is designed to make ongoing charger support clearer for commercial teams, site operators and installers.
Support & Maintenance
Sentinel supports remote issue triage, case handling, customer guidance and installer coordination where site attendance is required. Electrical repairs, parts and maintenance visits are scoped separately unless covered by a separate agreement.
Connectivity
Sentinel can help review charger network setup, SIM ownership, routers and OCPP connectivity paths. Connectivity replacement and ongoing SIM charges are confirmed during assessment.

Already have chargers installed?
You may not need to replace everything. Sentinel can help assess supported third-party OCPP chargers and identify whether they can be migrated, monitored or managed through PlugStream.

Clear scope from the start
Sentinel is a managed support, monitoring and migration service. It does not automatically include electrical repairs, replacement parts, third-party warranty cover, civil works, site attendance, SIM charges unless included in your plan, out-of-hours support, or guaranteed support for locked or unsupported third-party charge points.
Where site attendance is needed, PlugStream can coordinate with your installer, maintenance provider or one of our approved partners.
FAQ
PlugStream Sentinel questions
Answers for operators reviewing managed support, monitoring and migration options.
Do I need PlugStream chargers to use Sentinel?
No. Sentinel can also be used to assess supported third-party OCPP-compatible charging estates. Compatibility depends on the charger model, OCPP access, configuration, network setup and site requirements.
Can Sentinel support EO Charging customers?
Sentinel can help EO Charging customers assess their estate and identify practical support, migration or replacement options. We cannot guarantee that every EO installation can be supported or migrated, but we aim to preserve working hardware where practical.
Does Sentinel include repairs and parts?
No, not by default. Sentinel covers monitoring, remote support and service management based on your package. Electrical repairs, replacement parts, site visits and third-party warranty matters are quoted separately unless covered by a separate agreement.
Can you migrate any OCPP charger?
Not always. Migration depends on charger model, firmware, OCPP version, access to configuration, network control, existing platform lock-in and site-level dependencies such as load management.
Is Sentinel the same as a charger warranty?
No. Sentinel is a managed support and monitoring service. Warranty coverage depends on the hardware manufacturer and any warranty agreement in place.
