Home Energy Dashboard with Smart Plugs
Find the appliances that cost you the most with certified energy-monitoring plugs and Home Assistant's Energy dashboard.
You can measure household power safely without touching wall wiring. Certified smart plugs with energy monitoring report watts and kWh, and Home Assistant charts daily cost.
Never exceed the plug's rated load, especially with heaters and AC units. Do not open certified devices or wire anything into the wall yourself.

Questions
Whole-house monitoring?
Clamp-style energy monitors install in the electrical panel and must be installed by a licensed electrician.
