Turns out it was a couple of rechargeable LED flashlights. Ones that have low-voltage, solid state transformers that plug into the wall. Funny, they worked fine in my previous home. Thanks for all the tips, now back to programming!

Sorry, I meant unswitched outlets. I do have a lot of other devices on the same circuit. I'll start as you suggested by disconnecting everything else and resetting the devices. Thanks!

Yes, I tried switching PLM to different outlets and I have tried the LampLinc in the same outlet. I have also tried Range Extenders throughout the house to no avail. It's a small house (1400 sq/ft). Everything worked fine in my previous 2500sq/ft home. The furthest distance from the PLM is only about 30 ft.

My ISY994i system worked great in my previous home a couple of months ago. We downsized to a home 1/2 the size and now I can't get the ISY/PLM to connect to any PL devices. It reads my motion sensors and water leak sensors, so I know the wifi part is working. But when I try to connect to an Insteon LED bulb or an On/Off Module, it fails with "Cannot Determine Insteon Engine" or "Failed to Add Device, Reason 3". The devices I'm trying to connect are only a few feet away. I was able to connect to a bulb briefly once, but it disconnected and I can't connect to it again. I've tried two Dual Band Serial PLMs that were working before the move. The PLM and devices are plugged into their own switched outlets. I tried to connect to a LampLinc Module which was an existing device in the list and got "Cannot Communicate With XX.XX.XX.1 (XX XX XX 1) Please Check Connections" and the Event Viewer shows ERR 1". This is what the event viewer shows: Mon 06/12/2017 09:27:55 AM : [11 11 11 ] Added to list of devices to link to ISY Mon 06/12/2017 09:28:16 AM : [11 11 11 0 ] Failed to add device, reason 3 Mon 06/12/2017 09:28:17 AM : [All ] Writing 0 bytes to devices Something else that's odd, but probably unrelated, I could no longer connect the ISY with Firefox because I got "Java 2+ Required" error which I never got before, so I had to switch to Safari. Any ideas? Any place to start troubleshooting? Thanks Russ

Thank you for the quick responses! All good suggestions. I'm not sure why (yet), but "oberkc" had the answer. I had a scene relationship between the MS and light. I removed them from a scene and it works as expected.

I'm new to programming the ISY-994i, but I have 40 years or programming experience. Yet and I'm really struggling with a few ISY programming concepts. I'm trying to run this simple program to turn on my porch light when the motion sensor detects motion, but to only do so between sunset and sunrise. My problem: The light turns on when motion is detected, regardless of the time of day. I only want the program to work between sunset and sunrise. Here are the programs used: ------------------------------------------------------------ Rear Porch Light Status - [iD 0003][Parent 0001] If Status 'Rear Porch Motion Sensor-Sens' is On And Status 'Rear Porch Light' is Off Then Run Program 'Rear Motion Sensor Sched' (If) Else - No Actions - (To add one, press 'Action') ------------------------------------------------------------ Rear Motion Sensor Sched - [iD 0005][Parent 0001] If From Sunset To Sunrise (next day) Then Set 'Rear Porch Light' On Else - No Actions - (To add one, press 'Action') ------------------------------------------------------------ What don't I understand? Any advice would be appreciated.
