Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Stem Athena

  • Stem's site names the product PowerTrack Optimizer, formerly Athena, so the Athena name is retired
  • No price, subscription fee or contract term is published anywhere on the site
  • The optimizer is one component of the wider PowerTrack suite alongside separate EMS, SCADA, Power Plant Controller and Logger products rather than a standalone licence
  • Design, procurement, commissioning and operation are sold as managed services separate from the software

Trane Tracer Building Management

  • Tracer Synchrony software runs on the Tracer SC+ system controller, so the software is tied to Trane building automation hardware
  • Small and mid sized buildings are served by a separate product, Tracer Concierge, rather than the full Tracer SC+ system
  • No price, licensing model or subscription term is published on the building controls pages; the site directs buyers to a Trane sales office
  • The page states no hardware specifications or system requirements for the controllers
