Features

How it works

Solar and house consumption forecast, tariffs, planning. We work out the absolute minimum power to charge from the network — with the help of AI in the cloud. The add-on at home measures and executes the plan. Your network traffic's encrypted with industry standard security.

Plans the whole day, then refines

One running tally for today. Extra solar that comes in early carries forward in the plan, only the minimum generation deficit at the end of the day is what's filled from the power network.

Only the cheapest window

The day's network charge happens on the cheapest tariff available. If the battery gets below your minimum, we can buy on a higher tariff so you never run flat.

Avoid charging during the peak

You set a reserve and that's what has to make it through the evening until sunrise when the panels can charge up again.

Learns progressively

Your solar and power usage is reviewed daily. An adjustable correction gradually nudges tomorrow's plan toward what your home is actually doing.

AI second opinion

Every charge plan gets reviewed by an AI agent. An advisory check — if the planner missed something, we catch it before any network charge happens.

Yours to leave

You pick how long we keep your history. The home assistant add-on is open source — you can read every line of it.

Cancel your subscription and your data is deleted. An upcoming feature allows you to download your data on the way out.

Agent help (?) mode allows you to point to get instant help tailored to what's on your screen. Try it in the demo.

FAQ

Quick answers

What do I need to run this?
Home Assistant OS or Supervised (these install types can run add-ons). A GoodWe ET-series inverter connected to your home network. A free Solcast account for the solar forecast. No hardware changes.
Is it safe? Can the cloud touch my inverter?
No. The add-on talks to the inverter on your local network. The cloud only sends a plan; the add-on is the only thing that communicates to your inverter. monitor_only_mode is on by default and is controlled locally in Home Assistant - 100% under your control.
Does it support my tariff / energy provider?
We support time-of-use tariffs from most providers. You record your tariff windows in the portal for us to plan against.
We don't support Amber and other dynamic tariffs, and fixed-rate tariffs where you just have one rate all day long aren't compatible.
