I have one and only one Insteon 2477S installed. It beeps when it senses Insteon traffic. In the ISY 994 Admin Console , it said (2477S) Dual Band SwitchLinc On/Off Switch v.45. I did link it to the ISY.
I can turn it on and off. However, I cannot find a way to turn off the beeping. I have done a factory reset (using the air gap, waiiting 5-10 seconds, pushing in and holding, I get the two confirmation beeps) and that did not help. The Admin Console provides settings for On, Beep, and Backlight. For actions I have On, Off, Fast Off, Fast On, Query, Beep, and Write Changes.
Thoughts?
