It does sound like some transient or noise. Messing up the KPLs electronic. If you pull the Air Gap Switch on the KPL and wait a few seconds. Then gently push it in to its normal position {too far may reset it}. Does the problem clear up?

The ISY Maximums you listed are for the Pro versions of the 99i and 994i The Standard 99i and 994i maximums are 256 Devices/Scenes and 300 Programs.

Did you use the Start Linking choice when adding the devices and then stop the process after you where through with the Finish Button? Is the LED on the PLM still flashing like it is in the linking mode?

OH well. My manual was a real old one. Smartlabs strikes again.

Yes. That is what the manual says. Battery has to be removed and then reinstalled a few seconds later for the jumper change to happen.

blueman2; V2.4 is more likely the hardware version. That would be the number on a white sticker. What firmware version is reported by My Lighting?

Regular incandescent bulbs being used? The InLineLinc Dimmer isn't powered through another switch is it?

I have seen the internal photos of the 2491T in the FCC Database. It does look like it can take the Humidity Module. You may want to see if the module is installed as I believe it maybe an option. If not the HUM/NO HUM jumper is set to NO HUM.

I have seen some internal photos of the Dual Band wired in devices, in the FCC database. There antennas are not in an ideal place for coverage.

Teken; You just don't have any older hardware 2476S SwitchLinc Relays. They all didn't have an Air Gap Switch and used a 100% different Factory Reset procedure. My thoughts are the 2476ST was also developed from the before Air Gap Switch was added to the relay style Switchlincs. To factory reset a 2476S that has no Air Gap Switch: Hold top paddle for 10 seconds. Then release. Press the set Button and then release. Press the set button again and continue to hold it for 10 seconds before releasing. In a few seconds the load turns On and the Factory reset is complete. The Smarthome wiki also indicates the above procedure works for the 2467ST. http://wiki.smarthome.com/index.php?tit ... t_Settings

You may want to look at the 2411R Manual to see if your TV remote will work with it. It only accepts NEC IR Codes. Page 12 of the Users Manual gives examples. http://www.smarthome.com/manuals/2411R.pdf I believe the unit ships with a remote also. They also make IR Extenders. Where you point the remote at a IR receiver and it sends a RF signal to its mating receiver in another part of the home. It then converts it back to IR that can then activate the IR sensor you added to the 99i.

The 2412N Smartlinc is not compatible. You need a 2412S or 2413S PLM. The RJ45 connector on the 2412S and 2413S may look like a network connector but they have RS232 serial signals on them. Not a network connection like the 2412N has. The 2412S is discontinued and replaced by the 2413S Dual Band PLM. Since the 2413S does not provide power to the ISY99i like the 2412S did. Also get the optional power supply that fits the DC input jack on the ISY99i. http://www.smarthome.com/1223PS/Univers ... ply/p.aspx

Any linking and scene creation should be done through the Administrative Console. The Administrative Console doesn't know the manual links you did and will not show status changes and may eventually over write the devices link database as it doesn't know existing links are in it. Also if the modules are new. They are probably I2CS protocol ones. So ISY firmware 3.2.3 should be used.

Is it the Memory and Error LEDs that are flashing? That is a lost network connection indication. http://www.universal-devices.com/mwiki/ ... Y.27s_LEDs http://www.universal-devices.com/mwiki/ ... =Main_Page

Are the SwitchLinc and TriggerLinc module recently purchased? Did you do the linking and scene creation through the Administrative Console? Devices linked with the Manual Set Button Sequence will not show up in My Lighting.

Event Viewer Level #3 for a Query Insteon Engine for an I2 ApplianceLinc v.38. Dropped back to I1 as it thought all of the I2 features may not be supported as we know some don't.

I believe the wiki said below 2.7.15 only supported 512K or smaller. Someone may have more data for you. From what I see it. When you remove the old SD Card the firmware goes with it and you pick the firmware you want to add to the new one during the procedure.

http://www.universal-devices.com/docs/i ... rguide.pdf Appendix C of the Users Manual The wiki also has a page on SD Card replacement. http://www.universal-devices.com/mwiki/ ... an_SD_Card Mine had a 128K SD Card in it. I replaced mine and after loading the firmware and latest backup. All was restored properly. You can get the size of your present one. In Tools, Diagnostics, System Status. It shows the memory used and total size if memory serves me.

It is the Insteon messaging protocol being used. Between units. The original modules I have are I1 and use a standard message length. Took many messages to do things. I2 was added and used Extended messaging where more data could be sent at a time. I2CS added Check Sum calculations where the message was tested for errors. It also made some I1 and I2 messages not work due to the changes. So the software had to have I2CS features added. To complicate things. Not all I2CS modules have the whole set of added features. Some just refuse to do much while others you maybe able to add to My Lighting but not add to Scenes.

Too bad Smartlabs could not spring for a small label. Saying "This is a I2CS Module"

Installed with no problems.

Glad you found it. I always keep my boxes and packing material. On the off chance I have to return something. My problem is many times the item itself is gone but I forget to trash the packing boxes.

Are the replacements brand new? Latest ones are I2CS and need ISY firmware 3.2.2.

Have you tried the Access Point's built in communications test to see if they are on opposite phases and in RF range of each other. You could also have some power line signal issues. With possible noise makers or signal absorbers. Is the PLM in the same outlet or circuit as your computer equipment? Many computer power supplies can absorb Insteon signals and make them weak. Also if the PLM is in a surge strip. Some have noise filters in them that also absorb Insteon signals as noise. If you look in the Program Tab of the Administrative Console. You will probably see a 3:00 AM query of My Lighting. If any of the modules don't get back to the Query. The next time you open the Console you will see that Error Message. Have you tried the Scene Tests in Diagnostics? Sometimes it can show communications problems for you.

I had a feeling it was I2. As I think I have seen in the Communications Logs I2CS if that was the messaging protocol used.
