115v appliance on Smarthings outlet?

(Capitola Anderson) #1

I am fairly new to SmartThings, having received a hub etc for my wedding. I have one of the plug-in outlets (all my stuff is plug in and go as I can’t make wiring changes in my apartment). Will that plug be safe with a 115V window AC unit? The unit is currently plugged into the wall on a 120V circuit, and I’d love to be able to access it remotely.



You need to check the specific model. The specs will be on this site under the shop.

Do not plug the air conditioner into a pocket socket (That’s another name for a plug in outlet) that is dimmable. Only one that is labeled as “an appliance module” or possibly just a smart plug.

For the SmartThings branded “smart outlet:”

Maximum Load: 12A 120V AC

So you need to check the amps that the air-conditioner draws as well as the voltage. If it plugs into a regular outlet, it’s probably fine, but do check. Some appliance modules will handle up to 15 A. So there is variation.

You can also always write support@smartthings.com to be sure.

I am running a 12k btu unit off on my smartthings plug and have had no issues for months.


BTUs are telling you how much temperature the unit can move but it doesn’t tell you the power draw. Because you don’t have the efficiency factor. You could have a 12,000 BTU unit that would run fine on 12 A and another one that would require 15. So to match an air conditioner to a power receptacle you need to look at both volts and amps. The BTU in this instance is a consumer indicator showing the amount of cooling you will get, but not the amount of energy it will draw to get that cooling.

Agree however remember all new AC units are required to meet SEER requirements and their current draw must fall into a scale due to this. That being said if he has a 5-8k BTU unit it will draw less amperage than my 12k unit and it gives him a good idea of if the plug can handle the load.

My 12k BTU unit draws a max of 950 watts, real world around 550-650 when compressor is running. It’s a Kenmore something or other. Probably fairly typical of that size unit and it’s probably 10 years old. 12k is a pretty big unit, so I can’t imagine most people would have issues with this, but it is important to check!


Respectfully, it doesn’t.

It’s the specs that matter. The specs for the AC and the specs for the pocket socket. Both should be readily available by checking the manufacturers’ sites on the Internet.

Both pocketsockets and air conditioners can vary significantly in their power specifications. Plug a 15 amp air-conditioner into a 12 amp pocketsocket, and you have a problem.

There’s no reason to guess based on someone else’s sort of similar experience. You can just look up the specifications and get the answer. One of the things the Internet is really good for. :sunglasses:

I found this on the website
Amperage (amps) 4.9
Voltage (volts) 115

So it looks like it should work, yes?

Thanks for the help y’all!

Yes, that should be fine. Just in time for summer. :sunglasses: :sun_with_face:
