two, ok three, questions:

https://www.amazon.com/product-reviews/B0B14C719T
1) I found an amazon product review that says that smart plug product draws 0.3W when anything plugged in is "off" and 0.8W when something is plugged in & "on".   

a) is that accurate?

b) which number applies if the end use item (eg. lamp) is switched "on", but the smart switch is interrupting power / turning it off?
 

2) We'd like to be able to turn on a towel warmer and let it run for 2 hours, and have it automatically turn off.  I think I read that this can be done from the app.  Can this "program" be downloaded into the plug so that we can press a little button on the plug and have it run that program locally?

3) Specifications say up to 15A and 1800W.  If a towel warmer is 300 W - 600W, that works with the design specifications, correct?  

Thank you!
