Basic and barely functional
I just wish someone at Rinnai could just look at a normal scheduling application like NEST. The schedule process is so basic you have no choice but to us the wall control. The wifi unit will only do 2.4GHz band so is old school, and the app needs to reconnect each time you open it. Zones cannot be renamed, scheduling display is barely 1990 standard and the app just assaults you with flashing icons, fans, flames and warnings. Needs a rewrite.
