Posted July 12, 20178 yr Hello, For multi-way light switches (using Insteon 2477D switches), I'm wondering, what is best? To use the instructions I find here https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Multi-Way_Circuit Or, to use the instructions for setting one as a controller and one as a responder ON THE SWITCHES? I'm 'guessing' that to do this on directly on the switches programs the switch so that it will 'always' work? Like, if the ISY is malfunctioning or unplugged, etc. you'll always have the switches working as expected? Thanks!
July 12, 20178 yr Any manual links you do will not be known to the ISY994i. Eventually it will lead to problems. The ISY994i does the linking between the two 2477D switches. Even if the ISY994i is not working. The links in them will still work. Your Wiki link to the information should work fine. I have an On/Off module as a Responder to an older 2476S as a Controller. Through linking by the iSY994i. Even if off line the switch still controls the On/Off module. Edited July 12, 20178 yr by Brian H

July 12, 20178 yr For a conventional multi-way configuration, all devices should be designated as both a controller and a responder. An ISY controller is also a responder. It cannot be only a controllery. But a responder is a responder only.
