With Smart Plugs, what becomes of Always On


Some thoughts:

  1. You could test the data pipeline with a month long export as a POC to make sure things are working.
  2. Instead of removing by subsetting your could rename using the ID value early in the script: e.g. electricity_usage$Name[electricity_usage$Device.ID == “XXXXXX”] <- “New_device_Name#1”
  3. Once the ggplot is computed you can adjust the ggsave line to save the plot as a bigger png/pdf/jpg if you have a bunch of devices WITHOUT recomputing the plot. Handy if everything is squished up and the plot needs to be wider or higher. I believe that ggsave supports a width/height up to 50. I typically go up to 48 if needed. Happy plotting!

Take a look at the your web app Power Meter for the past 48 hours. You should be able to gauge your core home “Aways On” from that. I have found that my Sense environment does subtract smartplug Always On’s from the house Always On, but that smartplug Always On are:

  • Not the same as Idle some of time
  • dropouts and Off (vs. Idle) make smartplug Always On lower, often 0

I have also found a few big power users that I had never identified previously - My 1 yo garage door openers use 9W each, even when not opening, just listening for the click of a remote control.


6 hrs Later… Looks cool. Can you tell:

  • Summer from winter - Hint: AC in orange
  • When Sense stopped identifying our Model S, when I put in the new extension cable fix. Hint: Tesla in hot pink.
  • I have solar - negative energy in purple

Have you worked with Support on your issues with Always On. Those smart plugs should be getting reflected in your Always On figure. I’ll also mention this to the engineering team in the meantime.


Thanks. I did look at my power meter and the lowest value I found in there over the past 48 hours or so was 248W which I guess is still a lot higher then I would expect since before smart plugs I was between 160W - 180W (at least according to Sense). I guess each smart plug does use some power itself as well.

I have not, but I can send them a ticket I guess.


I did an experiment a while back using @duanetiemann 's utility to read HS110’s data. I saw about 2 W difference between two when stacked back to back on my record pump.


Suspect an HS300 would use slightly more.


Remember that Sense also rejiggered the Always On calculation at some point in time. A move from absolute min during a 24 hour period to a 1% statistical min during the past 48 hours could cause a big change in Always On if you have a low point in daily usage that is very short.


My always on went from 153 yesterday to 215 today


I’m gonna post this here though I think I have also posted a similar graph Data Analysis at some point in time. Based on my experience, the Sense Always On computation has moved around a bit over time. I identified 7 different “domains” since Aug 2017 based on my history, but some of the drastic changes may have been due to other factors, though outside of smart plugs, I haven’t drastically changed many things in my household to reduce Always On.

Always-on Ongoing Problems (reading high)

Just checked my always on and now it says 123 W

Also would like to point out that over the past week I’ve been playing around with the app and even looking at it on my computer to see whats been running and my wife keeps asking me what i am doing and i think its helping because she goes to bed after i do and she usually leaves a bunch of things on and I’ve noticed over the past week shes been turning more and more things off each day. I call that winning

I agree with rethinking what the ultimate goal of Always On is. To me, it’s a pseudo device representing all devices of a recognized constant load, but of unknown unidentifiable device/devices, if that makes any sense. I see some thinking of it as a device category. Sense doesn’t use categories, right? With these smart plugs maybe that can be added as device tag or something.

I think Always On should stay as it is. Because once something is identified then it should get its own bubble like normal, and drop off of the Always On. In a perfect world if everything could be identified would you still expect to have an Always On.

Others have mentioned Always On being a good low water mark. I don’t know about that. In addition to Always On you normally have other stuff running at the same time. So your total low point will be Always On + sum of other devices but, that’s only at a single point in time. I’d like to see low power averaged based on current filters Days, Week, Month, etc.


Everyone keeps talking about Always On being a Low Water Mark, so why is it not on the Meter View? Just a dashed line across the bottom saying Nothing (typ.) Gets Below Here

I do like the ideas of changing the shape so people don’t conflate Always On with What is Actively On. I saw the mockup above where the Alway On’s were pie charted. Personally, I would prefer if a bubble w/i a bubble view were made representing identified vs unidentified Always On
