Solar hot water with myenergi eddi in one home-energy view
See eddi hot-water diversion separately from household and EV demand, understand whether the energy came from solar, battery or grid, and keep boost controls within the supported boundary.
How sign-up works
This already runs in real homes, and supported homes can sign up today.
1app.energy is built around conflicts like this one. Start by choosing your inverter; supported homes create an account straight away.
Start with your inverter
Supported Solis, LuxpowerTek, Sunsynk and SigEnergy homes create an account straight away; other setups join the compatibility list.
Combination creates the value
Whole-home value comes from how devices work together, not from any single device in isolation.
Add your devices during setup
EV chargers, heat pumps, hot water and your tariff are added after sign-up, and each one shows what it supports.
Best fit
For solar homes with a myenergi eddi that want to understand hot-water energy separately from household load, battery movement and EV charging.
Friction today
- Hot-water diversion can disappear inside the home's total demand, making eddi value hard to explain.
- A daily hot-water total does not by itself show whether the energy came from solar, the battery or the grid.
- Homes with zappi and eddi need EV charging and hot water to remain separate even when both use the same myenergi account.
What improves
- See live eddi power and daily hot-water energy as a distinct part of the whole-home picture.
- Review the available solar, battery and grid contribution to hot-water energy without reconstructing it manually.
- Use a bounded manual heater-1 boost only where the installation is separately enabled, while monitoring remains available without control.
Typical workflow
- 1
Connect the myenergi account and let 1app.energy discover the supported eddi linked to that gateway.
- 2
Review eddi diversion beside solar generation, battery movement, grid import and any zappi charging.
- 3
Use the whole-home evidence to understand normal diversion, and use manual boost only where the supported control is enabled.
Related integrations
These device pages are the fastest route from the use case into product-specific details.
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.
myenergi eddi
Connect a supported myenergi eddi to see hot-water diversion separately from household and EV demand, with source-aware solar, battery and grid 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.
