NextGym operates multiple unmanned fitness studios that are accessible 24/7. The technical infrastructure was based on Raspberry Pi devices installed locally in each studio.
This decentralized architecture led to significant challenges: different configuration states, complex asset management, 3-4 hours of manual maintenance per studio and lack of central control. Scaling during expansion became increasingly difficult.
From 3-4 hours to just 5 minutes: Deployment time for new studios reduced by 98%.
100% automation and 24/7 monitoring ensure maximum efficiency and reliability.

Firewall, VPN, SSO and fine-grained access control
Integrated file browser for location-specific documents
A custom-tailored dashboard perfectly adapted to customer requirements that fully automates repetitive tasks.
Here you can see an overview of the various machines managed through the dashboard. In this example, a new machine 'Studio-3' is being deployed.

The software is pre-configured via templates. Node-RED configurations can be combined into template packages that are automatically rolled out when creating new machines.

Standardized fields for all important data: credentials, configurations, information and notes - everything centrally in one place.

Location-specific files can be stored and secured directly in the dashboard. All documents are exactly where they are needed.

Fine-grained permission management with individual firewall policies, SSO services and mesh VPN support for maximum security.
