There is a DTH and Smart App out there for the Wemo Crock Pot. Click on the link below. Community created. It works well. I use it. I haven’t tried to integrate with any other apps (CoRE, Rule Machine since I still use that, or SmartTiles)
You can also use IFTTT and work with Virtual Switches in ST if you want (that way you can get different switches on a Smart Tiles dashboard that will do exactly what you want)
If you look at the post below kevin’s in the linked thread, you’ll see everything IFTTT compatibility consists of for the Crock Pot.
So I would definitely recommend the Smart Crock pot. It has some benefits and features that make it worthwhile, even at the $100 or more price point.
You’ll be limited on what you can do with the plug-only method, but if you are looking for basic function, then this will work perfectly fine. For more granular control, you’ll want the Smart Crock pot.
