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

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.

Solis
Connect supported Solis hybrid inverter homes to 1app.energy so live solar, battery, grid, home demand, reports and tariff-aware battery behaviour can sit in one place once connected.
LuxpowerTek
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.
Ohme
Connect supported Ohme chargers so planned charging, charger state and EV demand can sit beside solar, battery and tariff context in 1app.energy.
Hypervolt
Connect Hypervolt chargers supported by 1app.energy through compatible cloud access, so charger state, sessions, EV energy and mode-based start/stop can sit beside solar, battery and tariff context.
Octopus Energy
Connect eligible Octopus tariff data for current rates, cost reporting and tariff-aware battery behaviour where the inverter is supported and Smart Control is customer-enabled.
EDF Energy
Connect eligible EDF tariff data and provider-created smart-charge dispatch context so supported battery behaviour can work around the home's real rate windows.
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 charges when power is cheap, keeps battery back for the home, and can export spare battery power when prices are high.
Home First
A simpler home-first mode. It runs the home from your own solar and battery first and avoids automatic battery export.
Time-based Control
A simple schedule-based mode. Time-based Control charges the battery during your cheaper tariff periods until it reaches the battery target you set.
