When I turn all of my relays on or off at the same time, there is a slight delay between each of the relays getting to their new state. Echo Room Controllers have a built in delay. When multiple relays are turned on or off at the same time, there will be a slight delay between each relay getting to its new state. The length of time is about 100ms between each relay and the next.
