I checked these out on their website and did a brief Google. I didn't see anything available in the U.S. yet. I wonder how much $$ they want?
My issues are all heaters can and will fail.
Now you have a heater, sensor, app, phone, wifi, that can fail. Another manufacturer introduced a wifi heater not too long ago. Seems a bit too much. How often are people changing their heater settings that they need an app?
That said I do like that fact it logs the temperature inside and outside the tank. You could see the correlation between your room temp and tank temp.
I'll probably just keep it simple and stick with a heater and an Inkbird.
