Verify you get a V2.5 that was recently reported in the Insteon.com web site. As having improvements. The sales pages have said 2000 Links since at least Memorial day. When I bough mine and it is a 2.4 with the 1000 link database as where some recently reported ones here. Has anyone verified that the ISY994i can actually do 2000 links?

No it is not usual for the TX and RX LEDs to flash in a pattern. If there is no Insteon traffic on the power lines or if the ISY994i is not doing something. The wall wart power supply for the ISY994i is a small switching power supply. So it should not be drawing any large current spikes. Though we have seen some reports of the supply occasionally being flaky. I have my ISY994i and computing gear on an APC Back-UPS-RS1000G with no issues. The UPS AC Input is on a 10 amp FilterLinc to keep its AC power conditioner from absorbing the Insteon signals as noise. With the PLM in the unfiltered outlet on the front of the FilterLinc.

When you are using an ISY994i. Do not use manual linking of modules. Allow the ISY994i to do everything. Also a good idea to do a Factory Reset on all new modules before using them. Test links are sometimes in a module from the factory and it can cause issues.

Ramping On and Off even after a power cycle or factory reset-restore. Sounds like the power supply is failing in the old one. Let us know how the replacement works.

Smartenit makes Insteon compatible modules. With multiple relay outputs or a mixture of multiple outputs and inputs. They would cost more than two 2450 I/OLinc modules.

Thank you for your contribution.

Thank you for the test jig project information. I am sure it will assist others .

If you have any plug in style Insteon Modules. The Factory Reset method is in its full manual. Many you can still hold the Set Button while powering it up. It will start Beeping keep holding the Set Button until the beep stops before releasing it. It will then double beep to indicate reset. Some of the newer ones you have to follow the flow chart of Set Button pushes and LED blink sequences in the full manual. To do the reset and other things. Like the built in communications tests in them.

You may want to look at the wiki itself. There are a few topics relating to the Portal and Alexa. Section 5 Add-On/Optional Modules for the ISY994i https://wiki.universal-devices.com/index.php?title=Main_Page

For the replace choice to be available. The old and new modules have to be the same or similar type. I suspect they will be similar enough. If the 2477D choice does not show up for replacing the 2476D. Then they are not similar enough. I know the 2635-222 On/Off module was not shown as a replacement. When I tried to replace a 2456S ApplianceLinc.

All the X10 two wire dimmer switches and the Insteon two wire switch. Steal power through the load and specified for incandescent loads. The models with Line Load and Neutral don't have to steal power through the load. So LEDs have a much better chance of working. The keeping one incandescent load in the mix frequently does fix the issue.

The X10 section here may not have any recent traffic. The official X10 forums are very well alive and have compatibility with LED bulb questions recently asked. http://forums.x10.com/index.php I would also suspect the bulbs maybe noisy or your X10 signal at the switch is marginal. Any new or moved electronic devices around the same time you changed to LED bulbs? Jeff has a great set of X10 troubleshooting tutorials you may want to look at. http://jvde.us/x10_troubleshooting.htm

What revision firmware is in on your ISY994i?

I don't think the Category and Subcategory are used by the ISY994i. The HouseLinc software read it and uses the proper communications protocol that model PLM or HUB would use.

Wiki page says 16GB. https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Replacing/Formatting_an_SD_Card

If you swapped the Serial Daughter board from the old 2413S in to the new 2413U. It probably should work fine. Only thing is if a program reads the PLM ID. It could see it as a 2413U PLM as the subcategory ID is different between the 2413U and 2413S. If the old PLM was a 2412S then the memory on the daughter board is a slower speed and probably the >2000 link size.

The photo I saw of the new trim plate. Has just the Off and On LED positions. To match the Off and On LEDs in the switch. The unused LED positions go all the way back to the original 2476S. So the relay and dimmers could use the same color change and light pipe kits. Now I wounder if they will have trim color change kits for the new style or if you want a different color. You get the older style and unused positions.

It is possible it didn't have a great demand. I have seen a few other things that maybe not in high demand disappear. Like some of the colors of the wall switch trim kits. IMeter Solo, SynchroLinc. I saw something on the X10 forums. The 2477S switch that can unofficially still accept an X10 address. Is getting a new designed paddle trim next month. Since only the full off and full on positions are used. The new trim has all the intermediate positions removed. For someone that wants to match the trim to their older ones. Can purchase the old trim kit . So that will be another change in the future.

The sales page says. Thirty Feet detection distance. Up to a ninety degree ARC and up to 150 feet RF distance. I suspect they are conservative ratings. So you could get more or less. Depending on the exact installation. Since they use a PIR sensor. I suspect things like bright light, heat sources like radiators, things like walls between the sensor and the module receiving the Insteon RF command. May effect things.

I know at 2.4. The serial port Daughter Board was completely redesigned. RS232 interface chip changed to one with better ESD ratings and both serial signals to the output jack. Now have what looks like some surge protection on them. To get more Link Database size. The memory chip on the Daughter Board would have to be a larger capacity one. Except for the larger {2000} Link Database. The rest of the features look like what they said comparing the old 2412S to the 2413S. Even my original 2413S V1.0 has a beeper, Red/Green LED, is lighter and faster memory over the 2412S. My V2.4 also has the same 24FC64 memory chip in it as the V1.0.

The PCB is double sided and some of the capacitors have a plated through hole. Linking the top and bottom sides. So care has to be used not to tear the plating out. Also the negative connections may connect to a heavy ground plane in the center of the board. A good soldering iron and good solder is needed. Things like a solder sucker or solder wick helps. If you are into electronics a nice desoldering machine is nice. Well I can dream anyway. I don't have one either. ?

When you put it onto the UPS. It filtered out all the Insteon power line signals to and from the PLM. You where using Insteon RF only. Adding the 2443 Access Point for added Rf to power line signaling. Got the Insteon power line signals onto the power lines.

Well even under the old private management. Nothing changed in the model number when the 2412S went from 417 Links to >2000. Just a hardware revision number. That was not posted for reference. It will be interesting if the whole Link Database can be accessed fast enough with the faster memory. The old 2412S slow memory caused errors if there was over about 800 links in it.

Thanks for the confirmation on the latest being a V2.5 My last one during the 25% sale was in fact a V2.4.

The firmware version should be shown in the Administrative Console where it is listed. In another thread here. There is a list of issues UDI has seen of features not working as they should. That they also forwarded to Smarthome for clarification and fixing. From what I saw. UDI got no real information on them and had to reverse engineer how to handle it.
