Most of the older models that could be made to turn on just with a smart plug have now been withdrawn for all of the safety reasons listed above.The reason that they worked with a smart plug is that they would return to their “on” status after a power cut/restore, and that has a lot of potential dangers.
However, because people really really want to be able to add these devices to Alexa, there are now some made with built-in Alexa integration that have additional safety features.
- Sunbeam makes a WiFi heated electric blanket, but it can be hard to find online

However, Walmart often seems to have the blanket available in store, although not always for shipping:
I’ve been told that some Costco’s carry it, but I’ve never seen it there.
- And Sunbeam also makes a WiFi controlled heated mattress pad:

- Beurer makes one for the UK:
- Eddie Bauer has one, but the Alexa integration may be limited: https://www.amazon.com/Eddie-Bauer-Collection-Electric-Alexa-Enabled/dp/B088KWRYLK?th=1
a friend of mine has this and says that you have to push a button manually and after that you can change the heat settings with Alexa. So probably not what you’re looking for. Some of the reviews say you can turn it on from the app as well, so I’m just not sure what the exact process is for this one. Anyway, it looks like it might be better to choose one of the others above, but I’ll leave this here because it will turn up in searches of Alexa controlled electric blankets.
- And of course if you’re willing to spend about $2000, the eight sleep mattress cover is still available with all kinds of Smart bed features, including heating and cooling and Alexa integration.

Not saying most people will want that one, but some people will. Choice is good.
