I feel a little explanation\reminder of this might be good.
When a bulk change happens in your home, such as groups of lights coming on at sunset, Tile Builder will receive notification of a change from each individual device. If there were 6 lights coming on it would receive 6 individual changes and regenerate the table for each event. This can be desirable in some instances and unnecessery in others.
What this setting does is reduce these group events into single events. It works this way:
When an event comes in Tile Builder sets a timer for the value selected, lets say two seconds (default) then the timer starts counting down. If another change comes in before the 2 second timer expires then the timer is again reset to 2 seconds. Once 2 seconds passes without any new activity then Tile Builder will generate the new table.
There are some tables where you won't care, such as battery or temperature and others where you will care, such as contacts or lights. Set this to the appropriate value for this purpose you have in mind. Even a 250 millisecond delay will reduce mass events into one or two refreshes.
