Shelly Plug S Gen3
Up to 12A / 2,500W resistive load · AC voltage, current, power and energy. 220–230V · Type E/F sockets. Confirm the exact regional electrical rating and local delivery terms.
Measurement profile
AC meter; region per source record: 220–230V · Type E/F sockets; measures AC voltage, current, power and energy; range Up to 12A / 2,500W resistive load.
What it is for
Measuring the running watts and watt-hours of European plug-in appliances over a realistic cycle.
Practical caution
The published 2,500W ceiling applies to resistive loads. Do not assume the same limit for motors, compressors or other inductive loads.
Working method
1. Confirm the appliance plug and supply voltage match 2. Keep the load below the documented rating 3. Record running watts and energy over a complete cycle 4. Use the measured average in Runtime Lab

Buying checks for the United Kingdom
Measurement path: Choose a meter made for the exact AC, DC, USB or battery path. Do not insert a low-voltage meter into a mains circuit. Safety rating: Confirm voltage, current, connector and measurement-category ratings from the exact manual before connecting a live circuit. Data you need: Make sure the meter captures the required value: running watts, startup event, accumulated Wh or battery current over time. Regional version: Socket meters and electrical accessories vary by outlet standard and certification. Verify the exact model sold for your country.
