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.
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 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.
