Apple HomeKit

  • Requires Apple device for setup and remote access; limited interoperability with non-Apple devices
  • HomeKit devices require manufacturer certification, limiting product selection compared to alternatives
  • Automations are more limited compared to open platforms like Home Assistant or professional systems

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
