We live in Montreal, Quebec. Family of 5. Hydro -Québec is the energy provider.
We saved almost 2 500$ the first year of using sense, quite easily.
Paid 1000$ CAD for installation, unit, a few smart plugs.
So worth it.
The app is not perfect. Yes, sometimes it detects the wrong thing, but the essential was to monitor energy. Quite easy.
And forget the small vampire things at 10w running all the time. The important stuff is all the big stuff. HVAC, hot water, dryer, etc.
Got the Hydro bill to prove it to anyone, if any doubts
Love the product. Really do.
