Released: February 20, 2026 Version 3.5.0 is a major release introducing a visitor tag logging system and a new assets layer that separates people and machine records from IoT devices.

Visitor Tag Logging

A new purpose-built workflow for managing temporary tag access for visitors, contractors, and other non-permanent personnel.
  • Quick check-in — Select or create a visitor record, assign a tag, and check them in with a single click
  • Check-out — Active visitor sessions are shown at the top of the Visitor Log page. Check a visitor out when they leave to record the departure time
  • Session history — Full audit trail of past sessions: who visited, which tag, arrival and departure times, and who performed each action
  • Safety event tracking — Open any session to see all incursions recorded by that tag during the visit window

Assets Management

People and machines are now managed independently from the IoT devices tracking them.
  • People Assets — New admin page for managing personnel records (staff and visitors) with name, employee ID, email, company, and archive/restore
  • Machine Assets — New admin page for managing vehicles and equipment with serial number, manufacturer, year, number plate, and archive/restore
  • Flexible assignments — Link any person or machine to one or more devices. Reassign a tag from one operator to another without losing either person’s history

Tester Device API

Field tester devices can now connect directly to SensorZone to manage tag assignments and visitor sessions.
  • Authenticate using a per-device API token generated from the admin panel
  • Assign and unassign tags to people in the field
  • Automatically create visitor check-in sessions when a visitor tag is assigned
  • Check out visitors when they return their tag

Platform Reliability

  • Streaming health monitoring — New health check endpoint verifies the real-time data pipeline is processing messages end-to-end
  • Improved connection resilience — The real-time message consumer now detects and recovers from silent disconnections, stuck connections, and thread failures automatically

What’s Next

We’re continuing to add more analytics tools and building deeper integrations between the assets layer and the Insights dashboards. Stay tuned for v3.6.0.
