Switching between "Program" mode, and "Override" mode

[MachRat]

Hi Andrew,

I just installed this today, and it works great. Thank you for the effort in creating and sharing this integration.

Using the Seely iphone app I can flip between "Program" mode (heating is controlled by the schedule I setup in the wall unit), and "Override" mode (heating is then controlled by my Home Assistant setup).

Quick question as I may be misinterpreting something. Is it possible to switch between "Program" mode and "Override" mode from within Home Assistant?

Thanks again for your innovation and efforts
