Have not done this in a long while. Maybe all the way back to my ISY99i. I too have never seen the "Goodbye"

The older Insteon modules could have an X10 Primary and Secondary address programmed in to them. My older 2476S Insteon switches with an X10 Primary Address also send an X10 On or Off when locally activated by the paddle and respond to my old HR12A Palmpad remotes. My old 2456S3 Appliancelincs also have an X10 Primary Address in them. The removal of the A10/X10 module would not correct your problem. As mentioned UDI can remove it if you want to. I also think one or more of you Insteon switches have an X10 address in them. The factory reset and restore. Will remove any X10 addresses. I have to add them back manually after a Factory Reset-Restore.

Unless something was changed recently. No it can't. It only displays the remote probe temperature on its own display and does not send it to the ISY994i. There is a long thread here. Where the internal sensor was disconnected and the remote sensor was connected. Then the remote probe data was sent to the ISY994i. http://forum.universal-devices.com/topic/9152-how-to-monitor-water-temp-via-isy-and-catch-more-fish/?hl=2441zth

Try the 2457D2 in a different location and see if there is an issue where it was installed. You can also open the Event Viewer in Level 3. And see if it is responding or not. When you try and add it.

The two wire is RF only. Since it gets its power through the load. It is strictly for incandescent or 120 volt power saving halogen incandescent replacements.

The 2413S PLM does not supply power to any model ISY994i or the older ISY99i. You need an external power supply. The older 2412S PLM did supply power to an ISY controller. It had a slower processor and memory. Was also Power Line only not Dual Band.

If the 2477D is not controlling to the humidity fan controller. It is possible the Insteon Power Line commands are triggering it. When you send the level changes to the 2477D. I have seen posts where the Insteon Power Line commands are effecting things like lights on manual dimmers that are not Insteon.

Beep Duration is for the time period an internal modules beeper sounds. If the ISY994i does not show a setting for the EZI04O relay duration. You will have to set it up with the Smartenit Utility Suite linked to in the thread. It needs a Insteon Interface to the power lines to work. Like a PLM {2412S/U or 2413S/U} or older PLC {2414S/U,2814U}. The PLC also need the SDM308 Smarthome Device Manager installed. I have seen things here where the ISY994i's PLM can be used. As it should alter the PLM Link Database. Remember to power down the ISY994i and PLM. Then connect the PLM to the serial port and run the Smartenit Utility Suite. When powering the ISY994i back up. Power the PLM first and allow it to initialize. Then the ISY994i so it can find the PLM during initialization. It will need a Serial Port connection. If you don't have a Serial Port I understand many of the USB to serial adapters will work. The needed Serial Cable is packed in the 2413S or 2412S shipping box.

Well you have to wake them up from their power saving mode. Part of the process is manually activating the Link Push Button.

If the Factory reset didn't cure the strangeness. Another possibility is you got a bad one. This was a new module not one from the recertified list? I have gotten bad ones from the recertified sales. One of the supposed 100% checked On-Off modules. Rattled and the insides where missing all the mounting screws and insulators.

If the PLM is on the UPS. Its power line conditioning will probably kill the Insteon power line signals as noise. Others have had a few Dual Band devices close enough. So the Insteon RF commands from the PLM work fine.

Normal as pointed out. Since battery operated devices go in to a power saving mode and will no respond to a Query. Even if you have Query modules at restart enabled in the ISY Administrative console. It will be blank until it sends a On Off or I believe it also has a heartbeat.

The recommendation to disconnect the I/O Linc for a few days and see if the problem continues. Would help in seeing if it is a Insteon issue.

What hardware revision is your 2450 I/OLinc? I did some snooping in a few revisions. The original 1.0 has a very wimpy power supply. 1.8 was better and 2.3 was beefier. So if yours is an older one it maybe failing hardware wise. http://forum.universal-devices.com/topic/21417-io-linc-hardware-differences-between-revisions/

The 2466S is an older power line only module. So power line noise could effect it being added. Even from a different device.

May not have been similar enough for the direct swap. New one may have added features the older one did not have. I saw the same thing with the new On/Off module. Was not close enough to an old 2456S3 ApplianceLinc for the swap.

Can't comment on your 2466SW specifically but I do know older firmware in many model modules. Act in a similar way. To what you are describing with no long beep. On a Factory Reset. I did find a manual indicating >5.0 and it does indicate the long beep and then two short beeps. It is possible it has failed.

Sorry I misread your last answer. If the PLM Link Count is still 0. That is definitely a problem. Have you tried a support message to UDI. They are fantastic with their customer support. http://www.universal-devices.com/contact-support/

40 maybe low. It may depend on how many devices you have.

At no point in the procedures. Did you use a Delete Modem (PLM) command?

Most of the Insteon modules. Have one or two 5 pin programming connector and need a programmer connected to change the firmware. Most are also power line derived power supplies. Done incorrectly you could end up landing on the place you sit down or worse electrical shock. My 2456S ApplianceLinc modules have the Logic +5 Volt supply directly connected to the 120 volt AC Line Input . One of the programming pad connections.

I looked at the transformers manual. Does yours have an internal timer adjustment triggered by a photocell to determine when the LED light come on? Maybe an option as manual was not 100% clear. I did see the optional output for added mechanical timers. I did see it could be used with an AC dimmer on the AC Line input. Rated to be used with inductive loads.

I have seen with my PLM from Amazon. Depending on when I searched. The default sellers page sometime was different. depending on when I did the search.

If the mechanical timers could be powered from the outlet on the side. 120 volts AC sounds more like it. Where the timers controlling the AC line Input to the transformer or switching the 12 volts to the lights. Controlling the AC input sounds more logical. Before trying a SwitchLinc Dimmer. I would check the transformers specifications ans verify they can be controlled by a dimmer on the 120 volt primary input.
