The old ISY99 was mentioned in the question. So I can't remember when my moth balled ISY99 could do. Those are in my ISY994i drop down list.

You may want to check the drop down list in the Administrative Console of the ISY99i. As its last firmware may not have the later Insteon modules in its firmware. So it could be properly controlled. I also think an On Off relay type is the safe way to go. As dimmers frequently don't like any inductive motor loads. There is also a small time in the AC Cycle where there is no current to the motor at the zero crossing of the AC wave.

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.

Looks like a unique setup. Did you by chance measure from the signal wires to the I/OLinc to ground. There is a chance the warmer has a line operated supply and has a potential to ground. Though if insulated well probably would be totally fine.

Well that sounds real scary. Glad you found it and removed it when it finally got cool enough to remove.

The faint slow blink sounds like the modules power supply is failed and there is excessive AC on the DC supply. Sounds like a new module replacement.

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.

Since the old style halogen bulbs flash. It maybe the module starting to fail. Some brand LED bulbs do flash on dimmer style modules and sometimes you had to choose different models to find some that would work. You may want to see that the connections to the module are good and solid. A power cycle may give you some information or a factory reset and reload the information to the module.

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
