First, for specific complaints, contact the developer. I think that’s the only way to get the app working up to the level of what you paid for your “smart device”.As some others have mentioned, this is not nearly as functional as the app for a Nest or EcoBee. Those dedicated apps are focused on a single product, whereas the Nexia app is scattershot across a diverse line of products. The only commonality between the products is the technology employed to allow it to communicate. Therefore the app lacks focus and control for an advanced item, such as a Trane thermostat.On the positive side, it does the very basics - change temperature, set schedules, etc. But for what we paid for the thermostat (or insert your Z-Wave device here), I would expect the app to closely match the presentation and functionality of the thermostat. Go to your Account on Nexia’s website, and you will see a nice colorful display that resembles what you see on the thermostat. It doesn’t fully replicate to actual unit, but it comes closer than the app, and is easier on the eyes.The unit is “smart”. There are tons of information available on the unit that can be accessed online - why is it not available for the user/owner? And why does the display have to be so Spartan?Ask the developers.
