Just doing some house cleaning on my insteon network and was disappointed to not have the ability do multiple device writes after doing changes to multiple devices. I reverted to the java console. Is this feature there and I'm not finding it?

On the Insteon protocal page, you can turn off "Automatic Writes to Devices" or "Automatic Writes to Battery Devices" similar to the buttons on the top of AC. I didn't find a Write to All Devices command, so I assume that once you turn this back on all of the stale devices will write but I haven't actually used this option either in AC or EISY-UI.
