How Do I Set Up the Home Assistant Energy Dashboard?
- Energy sensors not added to the dashboard
- Sensor lacks total_increasing state class
- Wrong unit (W vs kWh)
Problem Description
You're setting up or troubleshooting the Home Assistant Energy dashboard — it isn't showing data, or the numbers look wrong. The Energy dashboard needs energy sensors (grid, solar, battery, individual devices) configured with the right unit and state class, so most issues are sensor setup rather than the dashboard itself.
Why This Happens in Real Homes
The Energy dashboard is only as good as the sensors you feed it — it needs cumulative energy sensors (kWh, with a total_increasing state class), not instantaneous power (W), for grid, solar, battery, and individual devices. Most "no data" cases are the wrong sensor type or none configured.
Start in Settings > Dashboards > Energy and add your grid consumption, solar production, and device sensors, making sure each reports energy in kWh with the correct state class. Set an energy price for cost tracking, and give it time — the dashboard builds long-term statistics hourly, so a fresh setup looks empty at first.
Symptoms
- No data on the energy dashboard
- Numbers look wrong/negative
- Solar/grid not showing
- Device not appearing
- Data gaps
- Cost not calculating
- Sensor rejected by the dashboard
- Only partial data
Recognize these? Here's what usually causes it.
Common Causes
- Energy sensors not added to the dashboard
- Sensor lacks total_increasing state class
- Wrong unit (W vs kWh)
- Solar/return sensors not configured
- No cost/price configured
- Sensor resets confusing statistics
- Integration not providing energy data
- Just set up (needs time to accumulate)
Most fixes happen in the first 3 steps.
Do not factory reset your hub unless absolutely necessary as this removes all paired devices, automations, and settings. You will need to re-pair every single device from scratch which can take hours for a large setup. Always try a simple restart first.

Step-by-Step Solution
Add energy sensors to the dashboard
Go to Settings > Dashboards > Energy (or go to the Energy panel in the sidebar). The energy dashboard needs sensors configured for electricity consumption, solar production, gas usage, or individual device consumption. Click Add Consumption and select a sensor that reports cumulative kWh (total_increasing state class). Common compatible sensors: Emporia Vue, Shelly EM, Sense, P1 Monitor, or any smart plug reporting energy in kWh. Sensors reporting instantaneous watts (W) do not work directly — they need a Riemann Sum integration to convert W to kWh.
Fix missing or incorrect data
If the energy dashboard shows gaps or spikes: check the sensor entity in Developer Tools > States. The state should be a monotonically increasing number (total kWh consumed). If the sensor resets to 0 (after a device reboot), Home Assistant handles this if the state class is set to 'total_increasing.' If you see negative values or huge spikes, the sensor may be reporting incorrectly. Check the integration page for the device and look for firmware updates that fix energy reporting.
Add solar production tracking
If you have solar panels: click Add Solar Production on the energy dashboard. Select the sensor from your solar inverter integration (SolarEdge, Enphase, SMA, Fronius, etc.). The sensor must report cumulative kWh produced. Once added, the dashboard shows daily/monthly production, self-consumption vs. grid return, and cost savings. If your inverter integration does not provide a kWh sensor, use a CT clamp (like Emporia Vue) on the solar feed.
Configure energy tariffs and costs
In the energy dashboard, click the grid consumption sensor and set the cost. You can enter a fixed price per kWh or use a dynamic price sensor (for time-of-use rates or real-time electricity pricing). For fixed rates: enter your electricity rate from your utility bill (e.g., 0.14 per kWh). For variable rates: create a template sensor that returns the current rate based on time of day and connect it as the cost entity. The dashboard then calculates daily and monthly costs automatically.
Track individual device consumption
Click Add Device in the energy dashboard. Select devices that report individual energy consumption — smart plugs with energy monitoring (Eve Energy, TP-Link Kasa EP25, Shelly Plug S), or devices with built-in energy reporting (smart washing machines, EV chargers). Each device appears as a separate entry showing its contribution to total household consumption. This helps identify which appliances use the most energy throughout the day.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Place your hub in a central location in your home, elevated off the floor and away from your WiFi router by at least 3 feet. This provides the best Zigbee and Z-Wave signal coverage to all corners of your house.
Home Assistant issues that only appear after restart are a well-known quirk — triggers that require prior state history simply can't fire until that history rebuilds.
