The 2992-222 Range Extender when being sold. Was actually a 2457D2 LampLinc with the dimming parts not installed and a different firmware. Most now use the 2457D2 for both dimmer control and range extending. So that is a possibility. Depending on the exact situation.

Manual for the 2663-222 device attached. Since it has two controlled outlets. It has dual buttons. The 2473 is has a single controlled outlet and I see the quick guide was provided to you. See the full users manual for details. 2663-222-en.pdf

Yes they do basic X10 without the A10/X10 module added. I have it but never used it. As the added goodies where not needed or used. Thank you for jogging my memory.

Depending on the ZWave module installed. You maybe limited to firmware revision you can install. No personal information but you maybe able to remove it and install the last firmware released for the ISY994i The X10 module is gone as Guy pointed out. I got lucky. When the ISY994i was announced being discontinued but still available. I bought the X10 and Pro updates for my spare basic ISY994i.

I have also used an ESM1 to show Insteon power line signals and an RF Explorer budget spectrum analyzer to look at Insteon RF signals. Glad you found the RF problem. In the X10 forums we have seen lost remotes stuck in maybe a couch with a button on or an failing RF device start spewing X10 RF.

Have you tried a power cycle reset on the modules doing the RF conversion? Did you try one of the old transceivers to compare the results? In the Event Viewer is there any constant X10 style messages? Almost sounds like you have some RF interference that is almost over taking all the remotes.

There are some X10 and Insteon users here and I am sure they will assist you. You may also want to post on the X10 Support Forums. For added ideas. https://forums.x10.com/index.php

If you have remote control short distances some new ones have lights that make RF noise. Some makers sell bulbs tested to work with their openers. Since the I/OLink is power line only. If your control of the opener starts getting flaky. Putting its power plug on a Filterlinc may help or a Dual Band module in the I/OLinc's feed through outlet may also help.

One thing to consider. The OLD PLM's six digit ID is in all the modules will not respond to the new PLM' six digit ID. I believe replace modem will go out and write all the needed changes in the modules being controlled.

I had to take the top off mine to get to the SD card. Mine didn't align up well with the slot and when I clicked it to remove it fell into the unit. 😀

With out an SD card it should be impossible to even use it as it is where all the module information and programming is stored. I believe the early versions of the ISY994i had it internally and you have to remove the top.

Sounds like the switch is locked up or failed. Flashing red led usually indicates a communication issue to another module. You can try a power cycle reset by turning the power to it off and back on. Depending on its revision. Pulling the set button out should kill the power to it and then pushing the set button into its normal position. Will restore power to it. Do NOT push it all the way in as that may cause a factory reset. The tact switches under the paddles have been known to fail. Long time ago Smarthome extended the warranty on them in the known production problem time period.

2476ST is a power line only module. A restore as mentioned may do it for you. Locally does the LED bar graph move up and down when the paddle is uses? A factory reset and restore sometimes helps, but depending on its revision. May not have an Air Gap switch used in a factory reset. There is a method for the old ones. I have it if you need it. The information is on the sticker on the front of it. You asked about last firmware version for the 2476ST. It is 5.3.4. Though if everything is OK now you may want to hold off on the upgrade for now.

Looks like they are a V1 version and 1.6 is the exact version.

If your power line only deices. Suddenly start getting poor. The Access Points maybe starting to fail. If they are any Revision2 models. They are using the early revision of the 2413 base PLM main board. With the same capacitor issues. We have seen in the older 2413S PLM. The revision 1 Access Points are on the older base controller with the separate RF daughter board and seem to work better over the long run.
