Here’s why I wish my Envoy had an app: if I’m in it alone or with my wife late at night, we’re nude and with the lights off. It’d be nice to turn the tub lights on, however, from inside the house so we had some light guiding us to the tub. Our tub is in the lower level patio and we exit our home a little bit away. It isn’t critical, but it’d be another luxurious touch that we’d enjoy.
