Thank you, Mr. Bill. Clearing the java cache did the trick. I will use the ISY Launcher going forward.

Hi; My ISY firmware is Insteon_UD994 v.4.9.0 (2020-12-22-11:51:19) My User Interface is Insteon_UD994 v.4.7.3 (2018-07-09-16:44:35) I have a program to turn on my outside lights (a scene) if it is after sunset and IFTTT detects I have entered a geo fence. IFTTT tells Mobilinc to do it. This has worked flawlessly for years. Suddenly, the program now runs twice per day at 6:35 AM and 6:54 PM. There are no schedule settings in the Program, Mobillinc, or IFTTT. I reset the ISY controller and wrote a new program, with the same results. I have attached a screen shot of the program. Any suggestions would be appreciated. Thanks in advance.

Thanks, everyone, for the fast and informative responses. The IOLinc is now working correctly, i.e. triggered by both On and Off commands. Following otteporhis's very useful IOLinc options matrix (linked above), here's what I did: Removed the IOLinc from the ISY Reset the IOLinc to factory settings per Insteon's instructions Linked the IOLinc to the ISY Selected Option Momentary B for the relay (Triggered by both On and Off) Created a new Scene with the Sensor as a Controller and the Relay as a Responder linked to it Added the Scene to Mobilinc on my iPhone Note that this is different than how the Insteon Hub controller works. That controller did not require a scene to control the IOLinc with both On and Off commands.

Thanks for the suggestions. I thought the ISY controller is powerline only so a dual band device would not help. I have a lamplinc relay I can try. The insteon range extender is not supported.

I just switched from an Insteon hub to an ISY 994 (v. 4.7.3). I have Mobilinc HD on my iPhone (iOS 12.2). Everything seems to work as designed except the 2450 IO Link on the garage door. It works OK from the ISY console, but, from MobiLinc HD, only the On command will trigger the relay. The Off command is ignored. If I press the on-screen button twice (Off then On) it will work. Or, I can query the relay when it says it is On and it will cycle to Off and then work OK when pressed to On again. I reset everything (deleted the IO Linc form the ISY, reset the IO Link to factory settings, re-linked it to the ISY) and set the IO Linc Relay to Momentary B (IO Linc should respond to both On and Off). Still no joy. I have tried both settings in the ISY console: Momentary A (Triggered by either On or Off) and Momentary B (Triggered by both On and Off). Those are confusing. My questions: 1. Which ISY setting is correct? Momentary A or Momentary B? 2. What is the difference between the two? 3. What else can I try to get this to work properly? TIA.
