I use a smart outlet to monitor an automatic pump I have in my basement stairwell's "covered drain that is actually just a hole". I get an alert when the power hits a certain level or drops.
@mike Has a pretty cool use for this, I gather 
Personally, I use energy monitoring to see what devices are being used and create events based off of that --- our treadmill, kitchen appliances (I get a notification if pizza is done being made, or if someone made popcorn --- different gadgets that use power in certain ranges that are easy to detect). That's part of making all of this fun: "Hey, enjoy the pizza!", or not letting me turn off the lights in the morning if I don't work out on the treadmill.
I have an energy meter that tracks a Philips wakeup alarm for our roommate. When her alarm goes off, the lights in her room fade up as the light on her alarm fades up.
I use energy meters to detect when laundry is being done, as well.
I've yet to set up home-energy monitoring. I intend to use it to get a good idea of when our power is being consumed, though, and create an energy plan around that.
Wow, do you use point of use energy meters to achieve all of this monitoring? I have a whole home energy monitor and would like to set something up to monitor similar to this. There was a website called Biglee that attempted to do this but they went commercial only.
Most of my meters are Iris V2 Smart Plugs. They work well enough. I suppose my Inovellis support energy monitoring, but I'm not using that. I also have an Aeon whole-home monitor ... but I don't think that's operational, right now.
For each of those devices, I'm using RM. I intend to write an app (Which device is running) after I transition to a new hub, though.
I have a sense energy monitor that I use to track this data. It's nice to see my power hogs, but I still have a number of unidentified devices that are still pulling power after about 10 months. Would love to figure out how to integrate this more into my smart home.
I also have some newer Zooz/inovelli switches that I believe monitor energy usage, but haven't seen that field yet in devices in hubitat, unless I'm missing it
Is there a energy monitor that plugs into a wall outlet -- that hubitat can monitor -- and turn something on/off based on the energy monitor's reading?
I think what you’re looking for is power sensing. Very few available that can do this. Some Z-Wave (cannot recall which ones) and some Insteon outlets can do this. It’s rare
I use a Aeon HEM v5 to monitor whole house power usage and display it in a Grafana dashboard.
I like to look at it in the morning just to see if anything is abnormal. Lots of lights left on, compressor left on in the garage, etc. You can also get a feel for how much power your home is using at rest. In bed, nobody home, etc. From 22:00 to 06:00 you can see 450-470 watts. The smaller bumps in that time period are the chest freezer cycling. The bigger bumps are the refrigerator cycling.
I also have another dashboard with daily/weekly/monthly bar graphs of power/water/gas usage so you can compare previous usage.
For geek factor I'm also recording water and gas usage. For that I have a Raspberry PI with a SDR dongle listening for the meters to report.
No data earlier than Feb. That's when I moved from ST to HE and wiped my influx database.
I use z-wave outlets that measure power to detect whether my clothes and dishwasher are running.
Also, on the coffee pot, the light over the coffee station comes on dimmed when brewing is detected.
You can purchase about 9 of these for the price of a Sense whole home meter. I've used these to monthly monitor energy usage. I also used these to determine on replacing older freezers, and refrigerators that were using 2.5x the amount of energy of new ones that are even much larger. 2 years of energy cost difference = Price of New larger freezer. Did the same on televisions.
After a year I reduced my overall monthly kilowatt usage almost 800kw per month and have newer stuff just by replacing older appliances, televisions, etc.
Thank you to everyone who replied to my post. I now have many great ideas to try! Many thanks!
Awesome! Thanks! If this works then THIS is the answer for me!
I've recently decided to purchase a few smart plugs with energy monitoring.
Although this seems like a fairly simply question, I can't seem to find a simple answer.
Essentially, I'd like to know how to use hubitat/webcore/whatever to actually show costs of running an individual appliance (on a daily/weekly basis).
Any tips?
Here's the information for the device, if this makes the question easier to answer:
TIA
I am working right at this moment on adding energy cost calculation in this driver, as per the latest EU directives 
The plan is to add in the driver energyCost and energyDuration attributes (ready to be displayed on HE dashboard), similar to Kevin's "Zooz Power Switch" z-wave driver.

interesting.
I'm also pursuing the webcore forum, as there are some very clever people over there too.
reading all with interest... =)
Probably something more must be done regarding the energy monitoring in Hubitat on platform level, rather than individual and custom solutions. As already done in other platforms.
I'm assuming some sort of app would help.
I've been trawling the webcore forums and have so far not had a great deal of success.
The aim, I'm assuming, would be to remove the reliance on individual drivers, but that's so far out of my realms of understanding I almost can't even see it through a massive telescope =p
I can't see the whole picture of what would be the dreamed Energy Management system in HE (note, not just monitoring, but some kind of management as well), but important part of it should be the energy cost calculation.
For example, in my country, the difference between the electricity daily rates and electricity night rates is 6 (six!) times! After adding 3 additional taxes that do not depend on the rate, the final energy price ratio between the daily and night rates becomes 2:1, but this is still a very big difference. This is because we have a big excess of electricity power capacity during the night hours that can not be consumed by the industrial customers. So a lot of people are planning and doing their high electricity consuming activities during the late evening/night hours. Every modern washing machine for example has a delayed start - something that many people are using.

Bingo.
