Since you tried different cables between the PLM and ISY994i. The contacts in the serial RJ45 connector look good. The PLMs you have worked fine with other software using a PLM. Your ISY994i may have a serial port issue. I am not too sure what you can see if you try to look at the serial signals from the ISY994i. I never tried. the ISY994i signals just the PLM with some PLM Test programs. UDI is very responsive to problems from users. You may want to open a Support Ticket. https://www.universal-devices.com/contact-us Submit a Ticket choice.

Some Insteon modules have Local Control Sensing. Where you can have a lamp plugged into it and if the module is off. Cycling the lamps local switch from on to off and back on. Will turn the module on with out an Insteon command to turn it on. Some loads like LEDs can falsely trigger them back on. Most present modules should default to ignore but you may want to look at the full manual and see how to disable it if enabled. I believe the modules listing in the administrative console. May have an options tab where it maybe controlled.

A smart display. Would have more functions. Like a clock display or electronic control messaging signals and only a single pair of wires between the opener and the controls. Both the power and control information is using the same pair of wires. When you put something like a I/OLinc's relay or a simple push button switch on it. It shorts out the power to the console when activated and resets the console display. What you did in your modification was simulate pushing the control electronics push button to operate the opener and not directly short the power and control signals. Killing the remotes power and probably it did a cold reset.

I agree you should not have to do a reset on it periodically. Mine only gets reset if there is a long power outage and the UPS it is connected to powers down. If I do a firmware update or restore from a backup function. They do a reset as part of the procedure.

My latest 2413S PLM has one large sticker. Insteon six digit ID, model number, revision number and date code . Not sure when they went from two to one large sticker.

Thank you for the clarification. I was not aware of that HA had a way to interface with an ISY994i.

I may have missed something. Are you using an ISY994i and HA maybe to control it or HA and ISY994i both are accessing the PLM?

Older 2412S/U power line only or 2413S/U Dual Band PLM? The 2413S/U has had a bad reputation for its power supplies getting flaky. Causing all kinds of issues. If your is over two years old that could be an issue. The white date code sticker on the back may give you a clue to its age and hardware revision. The latest V2.5 seems to have had improvements in its supplies and has not been in use long enough to have a reliability history.

I don't believe it is a possible option. As I have never seen a reference to a users only log in.

Not sure on the suffix difference on the UI. The latest is 5.0.16C and on mine both are listed as 5.0.16C

Found these. Not sure if any of it would be of help. https://wiki.universal-devices.com/index.php?title=Main_Page#MAC_OSX https://wiki.universal-devices.com/index.php?title=Main_Page#Java_applications_are_blocked_by_your_security_settings

I would still contact UDI. They have the greatest support I have seen in a long time. They maybe able to diagnose the issue remotely or give you a answer here. Do you know what ISY994i firmware you are using and if the UI matches the firmware revision? Are you using the ISY Finder? You may also want to see what they have in the UDI Wiki. I am sure issues like yours have some answers there also. https://wiki.universal-devices.com/index.php?title=Main_Page I have seen some information of adding the ISY994i to a Java exceptions page but don't have any exact information.

The power On LED is driven directly from the power supply. If some of the other functions seem to act and work correctly. You may have a power LED hardware issue. I would contact UDI and start a Trouble Ticket. https://www.universal-devices.com/contact-us Where there any OS or Java updates done, that may have changed things?

My assortment of UDI power supplies. ISY26,ISY99i and two ISY994i controllers. Where 5 volt either 1amp or 500mA. Sounds like you found a good 5 volt replacement. I would imagine they would be fine.

I had a similar thing happen to me. In my case there was an added clue. The Power On LED on the supply was pulsing. The ISY994i has a range of voltages it can use. Right now if you get a replacement supply directly from UDI. It is a 12 Volt 1 Amp wall wart.

Glad you got it working.

When mine went bad. It had the same LED on the supply flashing you are seeing.

Did you use the special process to install the wanted firmware version before trying a restore. As it would not put the firmware on the SD card first? https://forum.universal-devices.com/topic/29346-cannot-restore-to-new-sd-card/

Thanks for the clarification on not being the same or similar. I ran into this when I tried the new Dual Band On/Off modules for the older 2456S3 ApplianceLincs.

Actually some things have changed. The Operational Descriptions and Block Diagrams where in the early Insteon FCC Database files. They where still in the 2413U/S PLM FCC Files. I suspect now that Richmond has taken over they have gotten more restricted on what the public can access. The schematics and parts lists for the 2414U/S PLC and 2412S/U older PLM. Where in the Developers Guides. Us early Developers Group members had access to. When they close the group. For awhile the developers information files where publicly released for all to download.

Did you add the new switch in the ISY994i and then use the replace with function to use the new switch where the older failed one was?

Teken. Don't hold your breath on seeing things like the users manual, internal and external photos. They are listed as available 09/16/2020 on the FCC web page. Things like the schematics will probably never be released to the public. Unless something has changed. They never released schematics publicly in the past and I doubt the new management will change things.

Thank you for the information. I will give it a look when I can. Seems with all the internet being used from home. Unless I try and do something lets say at 5:00 AM. Many of my pages never load or data is lost.

Restore Modem (PLM). Sends a factory reset command to the PLM and then restores the Link Database in the PLM. With all the links the ISY994i knows that should be in it. It also will remove links marked as unused or corrupt in the PLM Link Database. So there are no unused links in the middle of the ones that should be in the PLM.

When you reboot. Is there any message indicating the system is in safe mode? That can be it can't communicate with the 2413S PLM. If you go into Tools, Diagnostics, PLM Info/Status. Does it show connected and the PLM's six digit ID? Have you tried. Powering down the 2413S PLM and the ISY994i and then power up the 2413S before powering the ISY994i up? Is the LED on the side of the 2413S on at about its normal brightness? If the 2413S PLM is over 2 years one. One possibility it has failed. They have a reputation of failing after a few years. The latest ones V2.5 have some updates and should have a better service record.
