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

UPS units have a power line conditioner in them. That see Insteon and X10 power line signals as noise and absorb the signals. So another possibility is the UPS is absorbing the signals. Fix is the same a FilterLinc on the UPS AC input. I have a FilterLinc on my UPS and the 2413S PLM on the unfiltered outlet on the front.

Are the effected ones new enough to be Dual Band? The original power line only modules will not respond to a 4 tap or communications test. I too think you may have a new noise source or signal sucker. If only a few or many do not follow commands.

We can't update the firmware. Technically the folks at Insteon could. The PLM has two programming connectors. One for the RF controller and the other main controller. Though you need a programmer used for the model controller chip being used and the Source Code and we know that will probably never be made public.

Here is one I found. It is a common issue with the I/OLinc as it was not updated (as far as I know) to remove the All On response. https://forum.universal-devices.com/topic/42728-garage-door-opens-unexpectedly/page/2/#comment-379116

I have had similar findings with an ISY99i and ISY994i. Bad power supply and flashing power on led.

eiay or a ISY994i? If an ISY994i do you have the PRO model?

I am also using a V572. In my case I used the TW523 port on my XTB-IIR. Jeff's great XTB523 is also well known and works great. Unfortunately WGL has also gone out of business.

Yes like all RF only devices. You have to wake it up first. If you picked with the link management remotelinc2 method. I believe it gives you the method as you try and add it. I believe using the SET button to start it in the linking mode. Full Manual should have given you that. If you had the PRO option. On the top of the administrative console. Would be two added choices. For Automatic updates for RF devices and for Automatic updates for all devises. It also allowed a larger number of devices you could use with the ISY994i. If it didn't come with PRO. You would have to purchase it to add it.
