There's no need to probe the controller for a value that has just been read as we can easily cache it.
Scenario:
Some application reads a given temperature at 3 Hz. The thermostat only makes an update every 30 seconds or every 2 minutes, so there's little gained with the fast polling.
Solution:
For read-only values we should cache it and only request an update from the controller over serial if the cached value is too old.
