Smart tariff EV charging without home energy conflicts
When EV charging is cheap, it can still be operationally expensive if it competes with battery reserve, heating demand or export value elsewhere in the property.
Controlled rollout
This use case already exists in real homes, and onboarding is now underway.
The product foundation is built around conflicts like this one. Customer onboarding is paced carefully, so the next step is to review your exact device and tariff mix.
Best-fit homes onboard first
Homes where multiple devices already interact are reviewed first — rollout is selective and supported.
Combination creates the value
Whole-home value comes from how devices work together, not from any single device in isolation.
Setup review comes first
Tell us what is installed so we can review the safest and most effective rollout path for your specific configuration.
Best fit
For households using off-peak or intelligent EV tariffs who need the charger to work with the rest of the home, not against it.
Friction today
- The charger can consume the same overnight window the battery wanted.
- The car can look cheap to charge while forcing expensive daytime import later.
- Most apps optimise the charger but do not explain the whole-home result.
What improves
- Separate EV load from the rest of the house so its cost and timing are visible.
- Understand overnight charging in the context of battery reserve and next-day solar.
- Reduce hidden charger-versus-battery conflicts in smart tariff homes.
Typical workflow
- 1
Connect the tariff and charger context alongside any battery or solar devices.
- 2
Use daily reporting to compare charger behaviour against total import and net cost.
- 3
Tune the setup around real whole-home outcomes rather than individual device wins.

Connect supported LuxPowerTek hybrid inverters so solar, battery, grid and home-demand context can sit beside tariff and EV charging data in 1app.energy.
myenergi Zappi
Connect your myenergi Zappi charger to see EV charging in context with solar, battery and tariff data instead of guessing whether the car is stealing the cheap window.
Octopus Energy
Connect Octopus tariffs to turn raw device telemetry into cost-aware actions, daily savings reporting and smarter battery decisions.
Smart controls that usually fit this problem
These mode pages explain what battery strategy tends to work best once this use case shows up in a real home.
Autopilot
The best starting mode for most homes. Autopilot balances when to charge, hold, or export by weighing tariff value, later home coverage, forecast solar, and your protected minimum battery SoC so profitable export should not create later high-rate import.
Home First
A simpler home-first mode. It prioritises running the home from your own solar and battery first, minimises grid dependence, and avoids optimiser-led battery export.
Time-based Control
A simple target-based mode. Time-based Control charges the battery during your cheaper tariff periods until it reaches the level you choose, without optimiser-led export.
