Did you try a replacement or temporary substitute power supply? For the twitchy ISY994i.

Yes they can fail. Most where probably the older designed I1 power line ones but I have seen some of the newer ones also being reported as going bad. Newer ones went to a switching power supply and may have had the capacitor issues we see in the 2413S PLM. I have also seen not working tact switches under KPL buttons reported. I have had some 2456S3 ApplinceLincs fail. One actually started pulsing On and Off at about a 60 cycle rate. Replacing the capacitors in it fixed it. My ISY994i also had a power supply wall wart fail and I did a SD Card swap for good measure.

If trying a new power supply. Did not fix the issue. Checking the SD card and RJ45 jacks for bent or corroded contacts. May give you some added help.

Not too sure as they are not 100% the same. Try the replace with function in the Administrative Console. They maybe close enough to have the replace with do all the needed changes. https://wiki.universal-devices.com/ISY-99i/ISY-26_INSTEON:Replacing_a_Device

One caution. ISY994i powered off. Removing the SD card with power on would probably damage it. https://wiki.universal-devices.com/ISY-99i/ISY-26_INSTEON:Replacing/Formatting_an_SD_Card

I believe the Siren and older Alert Modules. Where two of the module. The Old Smarthome Crew. Didn't supply any programming data to UDI. So it was reverse engineering for both modules and I am not 100% sure it was totally controlled but that is my opinion and not official. I too am using the chime function not siren. It is really not a true Ding Dong for me. More like a cycle of high beeps and lower bops. Not what I would think being called a chime but Smarthme called it that!

Mine Chime is also Very Loud and I left the factory sound limiting sticker over the sound output port. Mine are also very early production and in my case. If I manually set anything with the side buttons. On a power interruption it powers back as Off.

On mine it had to be in a scene to set how it worked. In the main drop down list. I found setting the chime sounding time was not working until it was done in a scene.

I am glad you have the system working again. Thanks for the update.

All the modules in your system. Will presently have the USB PLM's six digit Insteon id in their link database's and will not respond to the six digit Insteon id of the serial PLM and probably would not respond to commands. Best to wait and properly change the PLM through the presently used controller.

Have you compared the links in the module to the ones in the ISY Administrative console? Are you turning on and off each individuate sprinkler output. As only one can be on at a time. If you have set output 8 to optional pump control. Is it turning on when any other output is on? If the outputs are actually going on and off. Have you verified the 24VAC sprinkler valve transformer is working?

After the ISY994i was discontinued. We where given a few months to purchase addon modules. Not sure about a portal modules but all the others are no longer available to be added. Also we had to use the My Account tab on the UDI web site to purchase modules in later years not the purchase module in the administrative console.

If you decide to recap your EZFlora module. Thay used a 2412 base PLM to build their modules but for awhile used the Dual Band 2413 PLM base for their modules. Before going back to the 2412 PLM base when we had the power supply issues with our 2413 PLM's. So yours may have different caps than we see in our 2413 PLM. So my thoughts on your module being power line only may not be correct if your is one of the modules using the Dual Band base assembly.

If it is in the Administrative Console but you can not control the module. Another thought if it is a power line only device. There could be a communication problem between the PLM and the module. You could try as a test. Putting a Dual Band module on the same power circuit and see if things have changed control wise or moving your module to the same circuit as the PLM. As a test.

EZ5010A Smartenit EZFlora. Is most likely a power line only module. As for awhile some did have Dual Band base units used. Is it showing in the Administrative Console. In the drop down list to manually pick the module type or found if you try the add it with the module identifying itself?

Try downloading the full users manual. Requires two users if you can't access the module and its circuit breaker. At the same time. https://www.insteon.com/support-knowledgebase/2014/10/1/outletlinc-2011-owners-manual

Is the standard USB cable. With the A and B connectors.

Jeff at JV Digital also has a great set of tutorials on things like noise. On X10 issues and many apply to Insteon Noise also. https://jvde.us/x10-troubleshooting/

Both of the firmware revisions are in the old 2412S power line only PLM. Comparison to a presently sold and completely different electronics 2413S firmware 9E. May not be a good comparison.

I would also be very interested in the information.

The Developers Guide may also give you some data. Is sort of dated by now but still has good information in it. http://cache.insteon.com/developer/developer-guide-022009-en.pdf

IndyMike covered things. I would second if you have older power line modules and the system is resorted to I1 communications. That takes eight message and acknowledgement for one link database replacement in a module. Noise and communication issues may effect the restore or PLM replacement messages.

Is the 2.6 on the white sticker of the PLM? That is the revision level 2.6 not the firmware. The probably version firmware is 9E. As I know rev 2.5 had the 9E and I don't think they went higher as 9E had been the standard over many revisions. Revision 2.4 and 2.5 have the new serial port board and power supply capacitors. So you should have the better PLM as the replacement.

If you are not in the 4Tap-Beacon-Communications test and your module has the blink LED on traffic and it is enabled. Noise can flash the LED. I have also seen some mention that noise can occasionally fool the polite feature in a module and it waits to send until it thinks it is clear.

The supply in the link. Is 12V 1Amp the converter for the other sized barrel connector adapter is .6A
