The challenge
Groendus wanted to operate its own CPMS without being tied to a single vendor. Previous setups gave too little control at the OCPP level and made it hard to shape tariffs, roaming partners and data flows on Groendus' own terms.
The solution
ihomer built and runs a fully serverless CPMS on AWS for Groendus. The platform speaks OCPP 1.6 and 2.0.1 to chargers and OCPI 2.2.1 to roaming peers.
Groendus holds a license to the CPMS and has its own access to the platform's source code, making it inspectable, forkable, and transferable into full ownership. ihomer runs the operation as a managed service; engineering decisions remain with Groendus. The serverless model scales with session volume without fixed infrastructure costs.
The outcome
Groendus adds roaming partners without vendor approval and pays for charging volume rather than reserved capacity. [VERIFY: charger count, session volume and cost comparison with the previous stack — verbatim figures live in the public AWS case study.]
