Here is the Wiki information on Purchasing/Activation and deactivation of add on modules. https://wiki.universal-devices.com/index.php?title=Main_Page#Instructions_for_Purchase.2FActivation.2FDeactivation

There have been a few threads here. On not being able to add a module with out removing one already in the system. By adding the Pro option to the ISY994i allowed the module to then be added with out removing a module installed already.

That sounds backwards. You should have clicked on the old KPL and choice the new KPL as the replacement. You probably wrote the old KPLs information into the replacement and now it does not respond at all. I do agree. The new one should have been found as the 2334-232 not a 2486D https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Replacing_a_Device

In the Configuration tab. The ISY994i can be told to Query All Devices and do any missed programs {there is a time period for the missed program} at reboot. If your program uses a motion sensor or open closed sensor. Their state will be unknown until it send a signal like Open or Closed. It is possible the unknown state maybe triggering your chicken coop door program/ If you have a PRO model you will also see the Automatic Write Updates to devices and Battery Devices On even if it was Off before the reboot.

That maybe a normal set of messages. I get the same information with some of my tracked USPS packages. Tells me it is moving in their system but no details where it is going next. I think it may have to do with what type the shipment is being tracked. Others give me every movement it is going through. Like In, sorted , then left that location. Some of my Ebay First Class with tracking are even less helpful. I get the Departed the USPS Regional Facility and the next one is the it was delivered to my mail box.

C7 and C13 are the ones in the switching power supply and the ones I would suspect. They should be a capacitor designed for switching power supplies. The V2.3 and above have a 100uF/50VDC laying sideways and now a Fujicon TY series made for switching power supplies. I have used a 10uF 50V cap in both the C7 and C13 positions with good results. C2 and C5 are they the ones on the serial port daughter board?

I have also seen the fairly uninformative USPS tracking information. In some of my tracking attempts.

One of the features of the Insteon modules is it remembers On level or Off state if power is interrupted and restored. Though always Off at power up could be done in the modules firmware. I know of two hardware revisions {Firmware} of the 2456S ApplainceLinc and two 2856S Icon revisions. Always powering to the Off state. Even if it was On at power loss. Earlier and later revisions went back to remember state at power loss. It would be nice if there was an option to pick Always Off, Always On or Last State after a power loss.

The full users manuals you can download. Have some typical 3 way wiring information. You sometimes have to reuse the Traveler wires between the two modules. So both modules can get a Line and Neutral power connection. Then you cap off the Red load wires in the locations not connected to the Load. Then the ISY994i can do all the needed linking between the two modules. I have also seen the Insteon Module quick and full manuals. They do give the manual linking information you can ignore with the ISY994i in use.

I have installed a few in 5.0.16A myself. It was not in the last official 4.7.3.

I am a retired Electronic Technician and a electronic hardware experimenter. Keep us in the loop on the new switches changes to the problem.

Though X10 related some can be applied to Insteon also. Jeff has a great set of troubleshooting tutorials. A few of them show noise from things like a cheap cell phone charger and some CFL bulbs. You may find some information that is helpful. http://jvde.us/x10_troubleshooting.htm I tried an o scope and as pointed out not much could be seen. I have tried the circuit ELA posted. Using an ACT CP000 Isolating Phase Coupler. I used an X10 XPCP as ACT is out of business. The Insteon power line signal frequency is not that far away from X10. Both are tuned for. It worked fairly well with my low end scope. Have not tried the new one I now have.

Yes the PLM does echo back commands sent to it. Plus any information the command asked for like a database entry. Terminated with an ACK. Some like a reset command may only be the command itself echoed and after the reset is completed an ACK is sent.

Been awhile since I was using Avast. At the time I did have to do a few configuration things to make it work.

From the Quick Start Guide. Pin #7 Common Ground. Both RS232 and TTL use pin #7 Common Ground. The RJ45 to DB9S Serial Cable in the 2413S box. Has a wire on Pin1, Pin 7 and Pin 8.

Thank you for the information. It will probably help others with similar findings. There have been a few other messages about the base ISY994i hitting the limit and adding the Pro feature corrected it.

Maybe the factory didn't put the jumper on one of the two pins for storage if not enabled. If you didn't download the latest manual. It is now on the sales page. It is 8.15.19 revision. Mine also does not say V2. Only place I saw it was on the file name of the latest manual I downloaded. No where on the sensor or box did it say V2. I have seen no indication of when the sensor itself was changed. The jumper was not mentioned in the earlier manual or shown in the internal photos in the FCC Database. It did look like there was two unused solder pads where the jumper is now in the photo.

I got one in the Black Friday sale. Is yours one of the 2844-222 V2 models they are now selling? It has a small two pin jumper below the USB Connector. Manual I just got says. If you put the jumper on. It sets it to Reduced Range. Specifications page. Range 30' with jumper Off. 20' Jumper On. I don't have any experience with the sensitivity setting yet but if you have the jumper you could start with a shorted range, Mine is a R3.3 1019. Reported Firmware in the Administrative Console v.47

A flat cover over the boxes front. Sounds like a good thing to try.

Here is the brackets page. Near the bottom of the page. It says not for mounting over an electrical box. https://www.smarthome.com/mini-remote-wall-mount-bracket.html

One possible failure is the 2413S PLM. It has a reputation of failing with a bad power supply. The latest V2.5 do have improvements in them that may make them more reliable. One symptom was link database was empty or very few entries. Restore would fix for awhile or it may have just been as you suspected a power glitch scrambled something.

If you go with the RemoteLinc2. The bracket is made for a flat surface. If you try and mount it in an electrical box. It will not fit.

One limitation of the 2474 two wire dimmer. Is it is designed for incandescent load only. Others have found that other types like dimmable LED bulbs may not work.

One thought would be an antivirus or firewall was involved. Or maybe one is using Windows 10 and the other one an older version.

Did you follow the part 3 step 2? Where you have to go online and use the link to start the Administrative Console for an SD card with no firmware. To then add the firmware. I don't think trying to write it locally is going to work.
