The short version

  • Only HOMER Energy has a free tier, so it costs nothing to try first.

  • They diverge on capability: HOMER Energy covers Microgrid optimization, TP-Link Kasa covers Affordable.

  • 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

TP-Link Kasa

  • Devices are sold individually rather than as a subscription, for example the Smart Video Doorbell Camera costs 49.99 USD and the 4-pack Smart Light Bulb costs 39.99 USD
