Like many of you I’m trying identify devices that make up the Always On mystery bucket and looking for help from the group.
On a typical summer day, with two IT professionals working from home, our typical power usage is 800 to 1,200 watts or 40 to 55 kWh per day. What’s driving me nuts is the 625 to 700 watts of Always On, of which 220 watts is identified (freezer, cable modem, wi-fi router, multiple computers and monitors).
According to my wife, I may have over done the smart plug installations with 6 Kasa HS300 power strips and 5 Kasa HS110 single plugs. Did you know a CPAP machine draws 3 watts, a Sleep Number bed draws 6 watts, a wireless headset charger draws 1 watt, and an Amazon Alexa Echo Dot draws 2 watts all day long? Lots of gadgets have been donated after realizing how much power they consumed and the rest put on switch power strips.
In the pursuit of knowledge (aka driving my wife nuts), I’ve turned off most of the circuits in my house, unplugged just about everything else and still had a phantom 400+ watts of Always On usage that I cannot identify.
Here’s what Sense or my smart plugs have identified:
- All TVs, Blu-ray players, Apple TVs, etc.
- All computers, monitors and printers
- Air conditioner, furnace, air exchanger, sump pump, sewage lift pump
- Fridge, freezer, dishwasher, stove, oven, microwave, garbage disposal, coffee maker, Instant Pot
- Washer and dryer
- Garage door, garage ceiling porcelain fixture LED lights, garage fluorescent lights
- Tools in my shop, even the 240V cast iron beasts
Here’s what Sense has not identified, there has to be more:
- Natural gas water heater exhaust fan – only runs when water is being heated
- Water softener – runs once a week
- Furnace continuous fan (~20-25 watts when the circuit is turned off) – hard wired
- Smoke & carbon monoxide detectors – hard wired
- Motion activated exterior security lights – hard wired
- Doorbell chime – hard wired
- Ceiling lights – all but 2 seldom used vaulted ceiling can lights have been switched to LED bulbs
- Ceiling fans – hard wired
Has anyone found odd always on devices that I should look for? Any suggestions for identify what makes up the 400 watts of unknown always on?
