The short version

  • Each has a real cost: Apple HomeKit requires Apple device for setup and remote access; limited interoperability with non-Apple devices; Helioscope licences are single user, so each designer needs their own
  • They diverge on capability: Apple HomeKit covers Siri Integration, Helioscope covers PV system design.

Where each one falls short

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

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

Helioscope

  • Licences are single user, so each designer needs their own
  • Projects are capped at 10 a month on both Basic and Pro
  • System size is capped by plan, at 1.25 MW DC on Basic and 5 MW on Pro, so a larger array forces an upgrade regardless of project count
  • Trackers, LIDAR modelling and API access sit on the higher tiers
  • Enterprise is priced per project with no published figure
