Care to share the competitors in the power monitoring space? I could really use a solution to this because my home electric bill is crazy high. We moved in to a new house about eight months ago and this electric bill is like 30% higher than my previous home. Not just the raw total of the bill - my consumption is higher in this house.

I know of sense.com but perhaps there are others?



I've used The Energy Detective for a long time, but it is challenging to install the hardware in your breaker box.

For an easier approach, there are a bunch of wifi plugs that can report energy usage: https://www.androidcentral.com/which-smart-plugs-are-best-mo...


A few other folks and I have recently reverse-engineered and built open source firmware for the Emporia Vue 2. Supports 16 + 3 clamps each, works together great with Home Assistant.

If it's an older refrigerator or a dusty house, check the refrigerator coils. In particular if it's set to a pretty cool setting but doesn't seem very cool or is running frequently it may be time for replacement.

You can also get any of a variety of temperature sensors (I like SensorPush) and stick one in the fridge to get a pretty good idea of how much it's running the compressor.

Another thing to look at if there's central forced-air heating/cooling may be whether it's set to have the fan always running. That can be useful in balancing temperatures between floors, but it's still a fan using electricity to move air.


I use Sonoff S31 smart plugs, flashed with Tasmota and connected to Home Assistant. It allows fine-grain monitoring of anything that plugs in to the wall, even if you disable the remote on/on switch (like for the fridge/deep freeze). LED bulbs use basically nothing and so can be removed from the equation, then all that’s left is built-in temp/humidity/air units and car chargers (though most of those have great metrics built in)


Our product was "site sage". Its subscription based and you have to install a current transformer around each circuit coming out of you electric box (you'd install in the circuit breaker box). But you did get circuit by circuit listings. Its also subscription based. The company has moved on to monitoring kitchen equipment, though they still sell them.

I've been out of the space for a while, but the "sense" power monitor was new when I left. It claims to use AI so you can just monitor the mains and it will suss out what is using power.

There were a lot of our home customers who were very obsessed with power use (trying to get to net 0 with solar). There have to be forums for this...

If you are looking for the manual way. getting a kill-o-watt and attaching it to your outlet is one way to see one of the things that takes a lot of power. I have the "Belkin" version which I like because the display isn't near the outlet. I'd suggest fridge... In my case my fridge was a large % of my power bill. Any electric heat.

Yeah, I’ve got one of those on my fridge, also.

When the monthly cost gets up to a certain level, we clean the coils and it drops back down.


Sense just guesses everything wrong. I can strongly recommend Emporia energy, which has per circuit monitors.


That's a good tip, I've been really disappointed in our Sense's ability to detect anything correctly. It's detected 9 heating devices so far. I suspect that our variable speed heat pump is hard for it to figure out reliably.

I ordered the additional sensor that I'll use for the heat pump and one more circuit and see if it does any better, if not, the Emporia seems reasonably priced for as many sensors as it has.


I purchased an Emporia unit and installed last night. Pretty rad so far. Only wish a single unit supported more clamps. My panel has 30+ circuits so it's tempting to install a second Emporia unit :)
