Part 7 of 7 · Home Assistant Energy Build
The dashboard
The human interface to everything built so far: a five-tab "My Energy" dashboard covering battery, live power, hot water and the Octopus tariff — shown here with the complete Lovelace config, genericised.
A system that automates itself still needs to be readable at a glance — both to trust it and to catch when something is off. The "My Energy" dashboard is the human interface to everything built in the previous six parts. It is a five-tab (five-view) Lovelace dashboard using the modern sections layout, set as the default view on the phone so a single tap shows the whole state of the house.
What the dashboard is for
The design brief is narrow on purpose: show state of charge, show where power is flowing right now, show today's energy and money, and expose just the handful of controls that arm the overnight routines. Everything else lives in the automations. The dashboard is a window, not a cockpit — with a few clearly-labelled switches. The five tabs are:
| Tab | What it shows |
|---|---|
| Home | Battery gauge, live power flow, quick controls, today's totals and costs, 24-hour history. |
| Timed Charge | The overnight grid-charge slot and AC charge rate. |
| Discharge Schedule | The discharge window that locks the battery overnight. |
| Eddi & Hot Water | Tonight's plan, Eddi mode, a manual boost button and energy stats. |
| Octopus | Live tariff status, costs, cheap-rate window, greenness forecast and Octoplus. |
The Home tab
The Home tab is the one that opens by default. Its header is a plain markdown title, ✨ My Energy, and it carries three badges across the top for the numbers worth seeing without scrolling: battery state of charge, a battery discharge-status sensor, and a Cheap Rate badge wired to the Octopus off-peak binary sensor.
Below the badges the sections run top to bottom:
- Battery — a single
gaugeof state of charge with severity colours (green from 50%, yellow from 20%, red at 0). - Live Power — the Power Flow Card Plus animating solar, battery, home and grid. As covered in Part 3, GivTCP's grid sign is inverted relative to the card, so the grid entity carries
invert_state: trueor import and export show the wrong way round. - Quick Controls — Eddi mode and Eddi power as tiles, with a markdown note explaining that
Stoppedmeans maximum solar export andNormallets the Eddi divert surplus solar to hot water. - Battery Control — battery mode, plus temporary Pause Charge and Pause Discharge tiles, with a note explaining Eco / Eco (Paused) / Timed Demand / Timed Export.
- Today's Totals — solar generated, grid in, grid out and battery charged, as coloured tiles from the GivTCP daily energy sensors.
- Today's Costs — export revenue, import cost and net position, with a note on the assumed export and import prices.
- History — two
history-graphcards (SOC over 24 hours, and power flows) withsun.sunoverlaid so day/night lines up with generation.
The power-flow card is the centrepiece, and the one card with a real gotcha worth isolating:
type: custom:power-flow-card-plus
title: Live Power Flow
entities:
battery:
entity: sensor.givtcp_gwXXXXXXXX_battery_power

invert_state: true # GivTCP sign is inverted vs the card
solar:
entity: sensor.givtcp_gwXXXXXXXX_pv_power
home:
entity: sensor.givtcp_gwXXXXXXXX_load_powerTimed Charge & Discharge tabs
Two tabs expose the raw GivTCP schedule entities behind the overnight routine. They exist so the schedule can be inspected and, if needed, nudged by hand — but the day-to-day management is the automations' job.
The Timed Charge tab is an entities card for the slot-1 charge schedule: schedule enable switch, start and end times, target SOC, AC charge rate, and battery mode. A markdown note spells out that it is managed automatically — the battery charges 01:00–02:00 at 48% (5.7kW) to protect the 32A breaker — and warns that externally-made manual changes will be reverted by the Settings Guardian from Part 6.
Why the discharge tab matters — The Discharge Schedule tab controls the window in which the battery is allowed to discharge. Outside that window the battery is locked — which is what stops it powering the Eddi during the overnight boost. The schedule is set automatically at 20:59/21:00 and disabled at 06:30, and the 🔒 badge on Home reflects whether the battery is currently locked.
The Eddi & Hot Water tab
This tab is where a human interacts with the hot-water side. It has four sections:
- Tonight's Plan — the opt-out toggles (
charge_battery_tonight,boost_hot_water_tonight) plus the boost start time and duration helpers. A note reminds that both auto-enable each evening and that start/duration are auto-adjusted to avoid overlap. - Eddi Control — Eddi operating mode and the active heater.
- Manual Boost — a duration input and a Boost Now button that calls a
script.manual_eddi_boost. It works even if the Eddi is Stopped (it switches to Normal first), and battery-drain protection stays active during a manual boost. - Energy Stats — hot water used today, the current session, and total diverted today.
The manual boost is the only place the dashboard does more than toggle a helper — it fires a script, via a button card:
type: button
entity: script.manual_eddi_boost
name: Boost Now
icon: mdi:water-boiler-alert
tap_action:
action: perform-action
perform_action: script.turn_on
target:
entity_id: script.manual_eddi_boost
show_state: falseThe Octopus tab
The richest tab, and purely informational — nothing here writes to a device. It turns the Octopus integration from Part 5 into something glanceable:
- Current Status — a markdown card with a Jinja template that reads the off-peak sensor and the current rate and prints a big green CHEAP RATE or red PEAK RATE banner with the live price.
- Live Now — import today, cost today, net demand ("Drawing Now", negative when exporting) and the current rate.
- Cheap Rate Window — the off-peak binary sensor and the next rate transition.
- Eddi Cost Tracker — today / this week / this month, from an Octopus cost-tracker sensor pointed at the Eddi.
- Yesterday Actuals — the bill-accurate import and export figures the smart meter reports (these land by mid-morning).
- Tariff Info — standing charges and export rates, current and next.
- Greenness Forecast — the custom card predicting how clean the grid will be over the coming nights.
- Octoplus — a conditional saving-session banner, points, wheel-of-fortune spins and the saving-session sensor.
The status banner is the neatest bit — a self-contained template card that colours itself by tariff period:
type: markdown
content: >-
{% set off_peak =
is_state('binary_sensor.octopus_energy_electricity_xxxxxxxxxx_XXXXXXXXXXXXX_off_peak',
'on') %} {% set rate =
(states('sensor.octopus_energy_electricity_xxxxxxxxxx_XXXXXXXXXXXXX_current_rate')
| float(0) * 100) | round(1) %} {% if off_peak %}
## 🟢 CHEAP RATE — {{ rate }}p/kWh
Cheap window active. Run heavy loads now — dishwasher, washing
machine, anything deferrable. {% else %}
## 🔴 PEAK RATE — {{ rate }}p/kWh
Peak pricing. Defer non-urgent loads if possible. {% endif %}The read-only Solar dashboard
The second user created back in Part 2 — the non-admin "Solar" account for a colleague — gets a duplicate of the Home view with the control cards removed. It keeps the SOC gauge, power flow, totals and history, but drops Quick Controls and Battery Control, so a guest can watch generation and battery state without being able to change charge schedules or operating modes.
Design note — Home Assistant doesn't enforce per-card permissions, so "read-only" here means a purpose-built view that simply never surfaces a writable control, shown to a non-admin account. It is the account model and the dashboard design working together — set up early in Part 2 precisely so it slots in cleanly here.
The full dashboard config
Here is the complete Lovelace YAML for all five tabs, exactly as it runs — with device serials, meter numbers and the account ID replaced by placeholders. Everything else (entity naming patterns, card options, the template cards) is verbatim, so it reads as a working reference for how a dashboard like this is wired.
Placeholders — gwXXXXXXXX is the GivEnergy Gateway serial, XXXXXXXX the Eddi serial, xxxxxxxxxx the Octopus electricity meter serial, XXXXXXXXXXXXX the import/export MPANs, and a_xxxxxxxx the Octopus account ID. Swap in your own values.

cards: []That completes the series. The system now runs its whole cheap-rate routine locally: capping charge to a breaker-safe rate, filling the battery and heating the tank overnight on ~7p energy, verifying the cloud-backed devices actually did as they were told, defending against cloud interference, and presenting the whole thing on a single glanceable dashboard — with a read-only view for a second pair of eyes.
Outstanding threads, kept honest: re-basing the dashboard totals onto Octopus meter data (Part 5), and the still-planned Alexa / Echo Show display. The build is a living system, and this log will track it as those land.
A personal home-energy project, shared as-is and not affiliated with any vendor mentioned. The dashboard config is shared as a reference — entity naming patterns are specific to this installation, and serials, meter numbers and the account ID have been replaced with placeholders.
