BLUCONNECT / GUIDE

Electricity bill calculator: which device uses how much?

Last updated: 5 October 2026

When the bill arrives it is hard to know which device cost what. BluConnect's energy screen uses metering devices directly and estimates the rest from wattage and on-time.

Metering devices

  • Smart plugs: Tapo P110, Shelly Plug S, Sonoff POW, Tuya and Xiaomi plugs
  • Whole-home totals with Shelly EM/3EM
  • Air conditioners and appliances that report energy

Your own tariff

Enter the unit price from your bill, any day/peak/night time bands, tiers, distribution fee and taxes. The app shows today's cost, this month so far, the month-end estimate and each device's share. Any currency.

Routines that save

  • Run the dishwasher and washer on the night tariff
  • Turn off AC and lights when the last person leaves
  • Cut standby-hungry plugs overnight

BluConnect is coming soon to the App Store and Google Play. Start free; upgrade to Plus when you need it. See plans ↗
