Good alternative for far located vents

The fan is good but bit noisy when at higher speed. I wish in app while setting up schedule it gives option to increase decrease the fan speed as well so that at night we can set lower the speed. During the time one is away it can be scheduled for higher speed to warm/cool down faster. This will make the unit more practical to operate.

Great experience

I’ve had a unit now for over 4 years. Still runs great and has been a game changer for temperature comfort in my main bedroom.

Copy function for Schedule

I just found a new function to clone the schedule, that is great. Is it possible to add feature to store settings for summer and winter?

Terrible, Keyboard Freezes the App

Trying to set this up right now and I have to type the name of the room but the keyboard coming up freezes the app.

This app must be vibe coded.
