It probably won’t work with the space heater, but it will depend on the brand and model of the space heater.
As far as Wi-Fi devices in general…
Smartthings has always had a few official integrations with Wi-Fi devices, such as the ecobee thermostat, Amazon Echo, the Ring Doorbell, and the Phillips hue bridge.
With the development of the new platform and the new V3 app, there are now a number of manufacturers of Wi-Fi devices who have created their own cloud to cloud integrations which you can access through the smartthings app. That includes TP Link Kasa. See the following review thread:
If you are still using the classic app, you cannot use that integration. Instead, you need to try one of the methods in the following FAQ:
The HS-105 will work, as stated by JDRoberts. It does support 15 amps at 110 VAC. Your space heater would have to be 110 V and < 15 amp MAX. Whatever solution you select, it must not only work with Smart Things but support the current draw of your heater and your house wiring must be at least 15 amp on the circuit. Blowing the fuse is not the plug, it is the total load on your house circuit (space heater and other devices!
Note: a smart plug does not regulate power output, it merely switches it on or off. If the current demand is greater than your house circuit, the BEST case is a blown fuse. Worst case is a fire.
Maybe you can help me figure out. I actually already own the ST branded smart plug. But the fuse ended up blowing in it. I just assumed it was because it was rated to low for the heater. But the fuse it takes is 15 Amp. And if I’m reading you correctly that should work with the heater as well?
It’s the one from Lowe’s, it should not be used with any plug-in pocket socket. You need a heavy duty device for it.
Always plug heaters directly into a wall outlet/receptacle. Never use with an extension cord or relocatable power tap (outlet/power strip) because of the risk of overheating the cord and the risk of fire. Extension cords are for temporary use only. If an extension cord must be used, it must be UL/CSA certified, rated at 15A (1,875W), 125V maximum with 14 AWG minimum and constructed of two current carrying conductors with ground. A heavy duty extension cord with the shortest length possible for the connection is recommended and must not be longer than 50 ft. (15.2 m). Do not coil or cover the extension cord.
It’s in the user manual that I linked to. They are concerned about The intermediate device catching fire. Heavy duty is defined in the part that I quoted. It’s a technical specification in this context.
There have been some people who were trying to get those Wi-Fi switches to work with other platforms, but I don’t know how far they are in the project. There’s a small chance that you might be able to give the switch to somebody else who could use it, but hopefully somebody will chime in here if they know. Nobody has them working with smartthings, though, that I’ve heard of.
