Grid Lens models every available plan against your real usage data — solar, battery, EV, and all — entirely inside your Home Assistant instance. Then it can operate your battery and shiftable loads on the plan it found.
The LP optimizer runs locally on your Home Assistant instance. Your energy usage data never leaves your network. Read our privacy policy →
No referral links, no kickbacks, no retailer relationships. We model all available plans and let the numbers speak.
Models EV chargers, hot water systems, and other loads you can shift to off-peak — so the comparison reflects how you'll actually use each plan.
Factors in your solar generation, battery storage, export rates, and feed-in tariffs for an accurate total cost picture.
Knowing the cheapest plan is only half the saving. The other half is running your house the way that plan rewards. Grid Lens plans 72 hours ahead against forecast solar and real prices, then optionally takes the wheel.
Charges, holds, and discharges your battery to follow the optimised plan — respecting your SOC limits, and handing straight back to your inverter's own EMS if anything goes stale.
Paint the hours each appliance is allowed to run, per weekday. Grid Lens picks the cheapest half-hours inside your rules — and you can override any load to On, Off, or Auto at any time.
When your battery is full and the surplus is heading out at a near-zero feed-in tariff, Greedy Consumption spends it instead — and can start a load ahead of a forecast spill rather than waiting for it.
Every automated action is visible on the dashboard: which rule fired, why, and how close the next one is. No black box deciding things about your house.
Add the Grid Lens repository to your Home Assistant App store and install the integration. It hooks into your existing Energy dashboard sensors automatically.
Enter the details of your current electricity plan during setup. This is your free baseline — Grid Lens will model it immediately.
Subscribe for $1/month to unlock all plans available in your state, updated continuously by our team. The optimizer runs locally — the API only delivers plan data.
A custom Home Assistant dashboard is added to your sidebar automatically — live energy flow, forecast vs. actual power, optimal usage, cost estimates, and bill projections for each plan over any date range you choose. No cards to configure, no YAML.
Everything automated is opt-in and off by default. Turn on battery control, or control for an individual appliance, whenever you're ready — and take it back with one switch.
