I see, I will go with Silver Envi as it has the App which you can access via your smartphone.
like you, i fancy Envi series..
but 3 private co. told me that the maintenance is higher when it is "smarter".
Hence i dropped back my choice to the the normal ones.
My room is abt 4by3 metre, the lady also suggest me, dun take so big BTU, if oversized, will have humidity problems, although their 12k vs 9k btu is only a different of $100 dollars, at the Daikin Proshop at Alexandra.
