The app does what it promises. You can see the heater but also start and stop, change settings via SMS by SMS or phone call - so far the price for my taste is quite high. The most important commands you could save as a template in the phone and use them when needed. Who does not, however, want to laboriously re-enter manual setting commands via SMS and is willing to pay for his laziness that comes here at his own expense. 4 stars because of the price.
