If you have not used the UDI Wiki yet. It is a wealth of good information. Tutorials and things like the ISY Cookbook. https://wiki.universal-devices.com/index.php?title=Main_Page

C2 on the serial daughter board. Is the DC filter capacitor for the 5V DC logic supply for its electronics. Probably OK as it is only the ripple of the supply. Could not hurt to change it if you want to. As an extra measure. Note as mentioned. V2.4 and above have a new serial daughter board. Its markings for that capacitor may not still be C2. Starting with V2.3 the two main power supply capacitors C7&C13 where changed to a different series capacitor. Made for switching power supplies. Starting with V2.4 the serial daughter card was updated. With a serial interface chip with better ESD ratings and the serial I/O lines to the outside world have protective components on them.

4.7.3 is not going to be updated further. 5.x was to be the next revision. 5.0.16 (RC1) is the one now being used and will have the updates as needed. Their RC releases are what will be official unless a very hidden problematic thing is found. I held off on a 5.x from 4.7.3 . I now have 5.0.16 and have had no issues and can now use the later Insteon modules 4.7.3 did not support. Like the Siren and short lived Alert Modules.

If the module in question has a internal Beeper. Many want you to hold the Set Button and plug it in. When the beeper starts sounding. Keep holding the Set Button until the beeper stops before releasing the Set Button. The module may then beep twice. I have seen a few modules that use a sequence of Set Button pushes and LED flashing patterns to do things. That information would be in the full users manual as a flow chart of actions. Though the hold set button while powering up seems to work with them also.

I personally would get it from UDI directly. Some of my Amazon purchases have been an older version. Especially from an Amazon Merchant. If Amazon gets them sent to you directly from Smarthome. They don't have any version ISY994i models in stock. That model number is a ZWave and IR PRO ISY994i https://www.universal-devices.com/product/isy994i-zw-ir-pro/

If you had to move the PLM a few times. That can be an indication you have power line issues. You don't have the PLM normally on the same circuit as the computing equipment or an UPS? Have you tested some of the communications with the built in communications tests {some manuals say Beacon Test others a 4 Tap Test} in most Dual Band Modules? 4 Tap is what I have seen. Where you tap the Set Button 4 times and it starts beeping or the modules LED flashes. Then you look at other Dual Band modules LED. Looking for a flash and color sequence. Some have to go through a Flow Cart of of Set Button pushes and LED flash patterns.

Before the new system was implemented. UDI use to manually transfer the module if you contacted them. . With the original units UUID and the replacement units UUID. Can't say about the old model ISY99i. As it has been gone since, I believe sometime in 2013.

Thank you for the very helpful information.

Not sure if this can apply to the older ISY99i or if the present method. Lets you transfer the purchased modules to another ISY controller with a different UUID as that is what the purchased module uses to see if it is on the correct controller. The registered owner can purchase modules, activate and deactivate registered ISY products they own. https://wiki.universal-devices.com/index.php?title=Main_Page#Instructions_for_Purchase.2FActivation.2FDeactivation As for the ISY99i being discontinued years ago. One of the reasons was. To support the latest Insteon Modules and their new features. The firmware to add them got too large for the ISY99i to hold and process correctly. That is why 3.3.10 was the last update for an ISY99i and eventually you will have a new module and no firmware support for it. UDI bent over backwards to help the ISY99i users for a long time and maybe it was time to let it go. https://forum.universal-devices.com/topic/10001-isy99i-series-3310-is-last-firmware-version/

PoliSY now has a section in the main forum section.

Thanks for the information. My Insteon use started well before the ISY line of products where designed. So I got use to my old fashioned notebook. I also don't use more than maybe 20% of the features, I could get use in my ISSY994i. I never even have used Topology. Basically I have been doing on added automation in many years.

I have bought some items from Supplyhouse. They are very reasonable prices and fast shipping if item is in stock. Just looked they have the T7900 in stock.

Unfortunately it is true. Along with many other items. If you search for the 2401L Kit. One of the hits is for the Smarthome page. It says Discontinued by manufacturer and no longer available. Same thing for the 2400L Kit for the Switchlinc Switches.

I put each of my Insteon Modules six digit ID numbers. In a notebook along with its location in the home.

The MSII when using the battery. Go into a power saving mode. You have to wake them up with its Set Button before you can access it. With the optional wall power supply it should stay awake.

The sales page shows. The ISY994i has Max Nodes 254, Max Programs 300. Pro models Max Nodes 1023, Max Programs 1024. Not sure if Error 1 is the message limits hit.

It does sound like you may have hit the limit. If you have a model that is not a PRO version. If you do not have a PRO model. You can purchase the add on module. https://wiki.universal-devices.com/index.php?title=Main_Page#Instructions_for_Purchase.2FActivation.2FDeactivation

Steve Lee at one of the Spring Electronic shows. Said new things are on the way but an NDA prevented comments on what was in the works. That said. It was maybe six months ago and I have seen no announcement or preorder offers. Gee maybe by the Holiday this winter. ?

Depending on its age. The EZFlora may have been using the base 2413 PLM main board and subject the same issues we have with the 2413 PLM power supplies. Early ones and what looks like present ones. Are on the older 2412 base main board with a real power transformer power supply not a switcher.

Actually. The ISY26 was replaced with the ISY99i. That was replaced by the ISY994i. I have both an ISY26 and ISY99i in a storage bin.

The NICOR catalog shows the DGD LED Lights use a remote driver box. So if you use a bulb for a test. It will have to be added to the 120 volt AC input of the remote driver box not directly across the LED assembly itself.

The Z Wave board and IR Board can be added to your ISY994i PRO You don't have to get a whole new one to get Z Wave and IR. The IR board can also be added to your present model. https://wiki.universal-devices.com/index.php?title=Z-Wave:_Ordering/Assembly_Instructions https://wiki.universal-devices.com/index.php?title=Main_Page#Upgrade_to_IR

The 2476D and 2477D are both three wire dimmers. I would also suspect a minimum load needed. Dummy load may help but it would add watts being wasted as heat. Have you an added incandescent bulb for one of the LEDs to see if things changed. Different brand LED bulbs may also act completely different. Maybe try a different brand.

You mentioned trying the NC and Common relay output. That is like holding the control button all the time and releasing it when the I/OLinc is activated. That maybe contributing to the confusion.

This has been seen by others. Here is one of the threads on the subject. There maybe more. https://forum.universal-devices.com/topic/10516-random-all-on-event/ I don't think this is part of the All On. Your UI is v4.6.2. It should be v4.7.3 to match your Firmware.
