HEMS for Home Assistant

Manage your batteries in Home Assistant without writing automations

Home Assistant sees everything, but decides nothing on its own. TED adds the missing brain: full regulation of your batteries, configured from an interface, with no code.

Sounds familiar?

  • Your battery automations run to hundreds of lines and you no longer dare touch them.
  • Every new device means rewriting everything.
  • You want a clear dashboard of what each battery is doing.

Why it is hard

Reliable battery regulation means smoothing measurements, handling limits, sharing power and dealing with failures. As Home Assistant automations, that is a lot of code to write, test and maintain.

Frequently asked questions

Does TED replace Home Assistant?

No: TED relies on Home Assistant to read sensors and send setpoints. Home Assistant remains essential.

Can I still use my automations?

Yes, for everything else. For the batteries, let TED decide, to avoid two systems contradicting each other.
