Controlling multiple devices at once

Hi!

If I want to control multiple devices, should I wait some time between sending new parameters to all the devices? Or can the parameters be sent in bulk?

ie. when closing all rollershutters for the complete house from openhab, should I just send DOWN to all rollershutters at once (ie. by using openhab’s grouping feature) or should I manually loop over all rollershutters and wait 1s between each sendCommand() ?

What is your experience with this?

Thanks for any clarification.

Hey,

it should cause no problems to send all parameters at once. When the devices use “wake on radio” there might be problems, but probably it will work, too. “Wake on radio” is used by the new valve drive and wall thermostat for example. But for both I would disable it anyway to increase the battery life. Other than that I think only the 19 key remote and the smoke detectors use it.
