I switch various lamps with the sockets. Five results are displayed in the daily view under "Energy": Today (kWh), current (amps), potential (watts), voltage (volts) and total (kWh) In addition to the daily view, the kWh consumed per month over the past 12 months is also shown.
Yes, consumption can be viewed by day/month/year. There is also an on/off log (for example for a heating system connected to a thermostat). I started in 2024 and I can go back to the beginning.
