Is there an official list of which current production Insteon modules still support X10? Maybe Tfitzpatri8 could get this information directly? I have found that this forum (and others) has in the past sometimes contained incorrect information on this subject. Likewise, the marketing information and manuals on the Smarthome and Insteon websites cannot be trusted to provide accurate up-to-date information as it pertains to this subject. At the very least, the list should include X10 support status for the following modules: 2477D, 2477S, 2334-222, 2334-232, 2475DA1, 2475SDB, 2635-222, 2457D2, 2450, 2442-222, 2443-222, and 2444-222. It would also be beneficial to know for each module whether or not the X10 support includes X10 Scenes. And finally, the list should state for each module the current production version number (Vx.xx).

No list needed as insteon is actively removing x10 from all of their devices. None of the few that still have support is capable of x10 scenes

X10 compatible:
2450 (iolinc)
Micro modules

I don’t have that info, you’d need to contact INSTEON directly to discuss your needs.

Even if they’ve dropped support for that protocol in all production lines, they may still have a supply of new-old stock in the corner of a warehouse to support legacy customers.

The list from lilyoyo1 seems correct, but incomplete, if one goes by what is stated in the manuals.

The latest manual for the 2334-222 and 2334-232 keypads is dated 7/25/2013, and the manual states that X10 and X10 scenes are supported. I have a 2334-222 keypad, V7.8, date code 5115, and it does indeed support X10 and X10 scenes.

The latest manual for the 2477D dimmer switch is dated 2/10/2015, and the manual does not say whether or not X10 is supported. However, I have a 2477D dimmer switch, V7.8, date code 0816, which does indeed support X10 and X10 scenes (contrary to what one might infer from the manual).

So I was hoping someone who has purchased one of these keypads or dimmer switches recently, say in 2018, could confirm whether or not current production versions of these still support X10. Not much of a response yet, it seems as if I am in enemy territory here, this being a Insteon forum, not a X10 forum.

Rev 7.8 came out years ago while they still had x10. The latest revision I am aware of it being removed was 8.2 which was last year. I don't use x10 but my information came from a reliable source so i am comfortable passing on that information. Yes the kpl dimmers did support x10 back in 2013. As many can attest the 2487s stopped supporting x10 years ago but the manual still shows support for it.

You could contact insteon directly for more information.

Back in February I emailed Insteon tech support and asked about X10 support for the Dimmer Keypad 2334-222 and the Dimmer Switch 2477D. At first, James from Insteon tech support told me that the Dimmer Keypads and Dimmer Switches are no longer X10 compatible. But this is contrary to what it still says in the latest manual for the Keypad. I wanted to get this straight, so I questioned Insteon tech support again, asking ... is the Keypad manual incorrect?

Sean (from Insteon tech support) replied: "At this time we have not removed the X10 compatibility out of our devices but we have stopped advertising the X10 functionality. We do expect in the next year or so to completely remove this feature as supporting X10 is not a part of our future road map and we never intended to keep that functionality for the long haul. When the change happens we will make an announcement on the site and remove the X10 references in the manuals. We started giving out the message you received over a year ago to help mitigate the pain when we finally make that move….so it won’t be a surprise… but for now they are still compatible."

So it is difficult to know who or what to believe. Maybe I will just have to order a 2334-222 Keypad and find out for myself.

I just purchased a new 2334-222 Dimmer Keypad and a new 2477D Dimmer Switch from Smarthome. I bench tested both, and both still support X10, as I was able to add an X10 address by following the usual method in the instruction manual. The 2334-222 Dimmer Keypad is Revision 8.0 with date code 4517, and the 2477D Dimmer Switch is Revision 8.2 with date code 3117.

I too am looking to migrate into legacy Insteon products to start.
are there any updates to the products listed in this thread?
I have roughly 100 x10 products installed in my house.
I've been researching how these legacy Insteon products work with x10
and it's been an uphill battle.
at the moment I'm relying on a Monterey Instruments Macro module IR
for all my x10 macros. Hoping to find an a Insteon (or other device)
that can perform macros across multiple x10 house codes from a x10 command. Not interested in tying up a computer or depending on the internet. want to keep my system stand alone.

Few things to consider. With X10 primary addresses in an Insteon module.

Most of the Insteon modules need a Neutral power connection to work. The X10 dimmer switches are two wire and steal power through the Load. Verifying a neutral would be best.

Multi way switches with Insteon or an X10 primary address in an Insteon module do not use a traveler wire between the switches. Each gets linked together to control each other in Insteon and an X10 primary address in them for X10 control. One has the Load wire to the load the other one is capped off. Both need a Line and Neutral power connection.

If you use the local control paddle or toggle button. Unlike X10 it will send a X10 or Insteon command back to the power lines.

X10 dimmers use the standard On Full and dim down or the Extended X10 command to dim.
Insteon modules with an X10 primary address also can use the full On and dim down or a %Dim command. So things like X10s CM15A can not dim an Insteon module with the Extended X10 dim command but should be OK with the older standard dim.

I did a test with an X10 CM15A with AHP and a Smarthome Essentials X10 compatible 1132CU controller. Using the other protocols controller. Some did not work exactly as expected.

Many of the Insteon devices on the list are currently not available because of Covid, or have been discontinued.

Smartlabs now has the new Nokia Smart Lighting product line, so is unknown how long the legacy Insteon products will still be produced.

Might not be very wise at this time to migrate into legacy Insteon.

Over on, member brobin has been recommending the Smartenit Harmony P2 with a bundled Insteon 2412U PLM, cost is only $60. Smartenit also has more capable hubs if you want to spend a little more.

A Smartenit hub is the way to go for those with large X10 installations, it handles X10, Insteon, and Zigbee, along with a smartphone app and voice control via Google Assistant or Amazon Alexa.
