⚡ Track What Energy Actually Costs You

My energy bill goes up and I have no idea what is causing it. Build me an energy cost calculator. Keep tariff rates as editable records including standing charge and any day or night unit rates. Let me log meter readings by date, and separately list appliances or areas with their rated power and estimated hours of use, so I get an estimated cost per item as well as an actual cost from the readings. Show cost per month, the trend across the last twelve months, and the same month a year ago for comparison. Rank items by cost rather than by consumption. Add an AI agent that reads the last few months and tells me plainly which one or two things are driving my bill and what a realistic reduction would be worth in money. Automate a scheduled monthly reminder to take readings, and an alert when a month is materially above the same month last year. Two logins: an owner who sees all sites, and a site user who logs only their own readings.
