The EZIO8SA should report status changes when an input is tripped such that query’s are not needed.
If you’re looking to trigger a relay on the same EZIO8SA as the input that is triggered, you’ll need to use the Utility Suite and look for the “Insteon All_Link Group Commands Settings:” box under the “Inputs Settings and Monitor” tab. You’ll select the input you want to trigger the corresponding output, click in the check box for the “Actuate Output”, and then click the “Write” button in that section.
The EZIO8SA works in one of two ways when linking for scenes. You can have a controller link to a single output or can link to the EZIO with the “Snapshot” method. Both methods are described in detail in the Quick Start Guide.
I hope that helps.
