Installment 4 - Revisiting ON/OFF with another month’s worth of smartplug data
I wanted to do one more round of analysis with:
- Another month of data - my smartplugs first entered service at the start of November
- Removal of most of my data dropout hours during the smart plug period - 382 partial hours removed.
Always On vs. power consumed by smartplug devices. Maybe not the smartest thing to look hour-by-hour since Always On adjusts over a far longer period, but I though this was interesting. Dropouts likely led to big Always On variances, even with dropout hours removed. But the good news is that Always On seem to be stabilizing again for me (and at a nice low value - 200W or so)
Playroom Cluster - access point and gaming PC. You can see the “ON” hours where the graphics card is engaged !
Washing Machine - our washing machine seems very efficient, seldom using more than 100W, despite pumps and motors.
Family Room Cluster - home AV system. When it’s off, it still uses 25W, 125W when we’re watching (LCD TV not included)
Office Cluster - laptop, monitor, 2 additional drives. 4 modes, from lowest to highest
- Laptop traveling but monitor and drives still in standby
- Laptop docked, running background stuff
- Laptop docked, running simple foreground stuff
- Laptop docked running intensive calculations / graphics (BUT NOT GAMING)
Sonos Units (2x) - High standby but low incremental power usage when playing. Really takes cranking things to go outside of 25W
Hot Water Recirculation Pump - Should be digital (1W-off or 45W-on) due to timer, but that little hump in between is real. Happens every midnight. Must be because the clock on my timer is off by a little bit.
Master Bedroom Cluster - access point, main Tivo, AppleTV and server. Who knows what the lower hump is ? Maybe the TiVo sleeping every once in a while when it can’t find anything to record.
Furnace Up - seems to make sense. Main peak is 5min/hr minimum fan set on my thermostat. Further to the right are longer duty cycles. I need to investigate the lower peak.
Furnace Down - Similar behavior to upstairs furnace, but more frequent duty cycles. Runs for a much longer time daily during the winter.
Service Closet Cluster - cable modem, router, cable amps, main switch, a couple bridges. Each individual component never varies by more than a watt. Pretty much 38-39W all the time.
HP LaserJet - very impressive. 2W most of the the time. Spikes during printing but never more than 12W in an hour.
