Home Assistant Energy dashboard
Home Assistant has a dedicated Energy dashboard for consumption, production and cost over time. ZiggyMeter's cumulative energy sensors are exactly what it wants: monotonically increasing totals, straight from the meter that bills you.
Configure it
Open Settings → Dashboards → Energy, or go to the Energy dashboard and select Configure.
- Under Grid consumption, add the sensor for energy imported from the grid.
- If you export — solar PV, for instance — add the export sensor under Return to grid.
Which sensor to use
| Integration | Grid consumption | Return to grid |
|---|---|---|
| Zigbee | ZiggyMeter Summation delivered | ZiggyMeter Summation received |
| Native (Wi-Fi) | The sensor for OBIS 1-0:1.8.0 | The sensor for OBIS 1-0:2.8.0 |
If your meter uses tariff registers, 1.8.1 and 1.8.2 are day and night sub-totals of 1.8.0. Use the total unless you want to bill the tariffs separately — adding both the total and its parts double-counts.
Give it time
The Energy dashboard aggregates hourly. Nothing appears until at least one full hour has passed with two readings to compare, so:
- On an hourly schedule, expect the first bar after about two hours.
- On a daily schedule, expect a day.
INFO
The dashboard's resolution can never be better than your reading schedule. A device reading once a day produces one data point a day, however the dashboard is configured.
Costs
Home Assistant can attach a tariff to each sensor — a fixed price, or an entity carrying a variable price. Because ZiggyMeter reports the meter's own registers, the totals match what your supplier bills, so the cost figures are directly comparable to your invoice.
