Yes. The old 2456S3 ApplianceLinc was a single band power line only module. I have see two major versions of them. V1.3 was the original ones and v4.? (seen a few revisions) a slightly better design. V1.2 was a recalled revision as switching certain loads would cause the magic smoke to come out. 😀

You may have an intermittent power line noise or signal sucker issue. The range extender or any other dual band module. Will receive the sensors RF signals and pass them on over the power lines back to the main setup. If the sensors RF signal is not getting back to the main setup alone. If it starts again. Try and make a note of what maybe running when the issue stares again.

It does sound like a range issue, interference, power line noise. As it worked in the office and could be added closer to the PLM. That is probably the device receiving and sending the sensors RF signals. You are having problems adding the sensor not trying to add the range extender. That I believe is not possible to add the the system. If you have an LED type light in the opener try temporarily removing it. I have seen report of some causing problems. If you unplug the opener itself. Can you then talk to the sensor? I have seen some openers electronics. Reported to cause issue and having to be on a FilterLinc to isolate it.

Another point. The I/OLinc besides being power line only. Also has a small switching power supply in it and the old Smarthome did the different sized capacitors trick. The early revision 1.0 has what I would call too low a sized capacitor in it and when the relay is on. The power supply voltage sages. That may or may not effect your setup. If the unit is older and has aged.

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.

Could also depend on the KeyPadLinc's age. The early ones where also power line only.

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.

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?
