Where each one falls short

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

HOMER Energy

  • Now owned by UL Solutions rather than being independent
  • Split into three separate products, HOMER Pro for off-grid and microgrids, HOMER Grid for bill optimisation and HOMER Front for utility-scale, so the right one depends on project type
  • Pricing is not shown on the product pages

Nest

  • Pricing not published in support documentation; individual product prices vary significantly
  • All Nest products require Google Home ecosystem integration for full functionality
  • Smart home devices operate only within the Google Nest ecosystem; limited third-party interoperability
  • Support and product documentation dispersed across Google support rather than centralised Nest site
