That's a very cool device! Currently I can turn my drain and water off and on remotely, but the water heater has been the item that forces me to go to the basement every time I visit my cabin. This could end that trip outside at night!
I don't see much information on how to use this device. 2 questions for me:
1) how do you set the hot temperature point?
2) can you manually operate it if the power is out?
I think I saw some mention of #2 being possible in the reviews on the company's web site.
thanks again for posting this.
