That sounds correct. The ISY will not show an X10 address in a module. If there is an X10 command it should show in the log or if active in the Event Viewer.

I saw Alexa was one of the effected servers. It was a problem with the Amazon Web Service and it effected many sites that use the AWS.

Saw this internet outage on the early news this morning. It was also effecting my news casts though my Roku streamers.

Found my 2413UH manual for the Houslinc 2416 Houselinc sales kit. It was from2012. It may work fine but as others have indicated. I know the ISY994i must not have checked the Subcategory as users had used them. With the serial version 2413SH It may have older firmware and components from what is presently sold. The information on the back label would give you some data. Like revision number and production dates.

2413UH is the USB version used by their purchased version Houselinc software. It has a different Subcategory number their software checks. Not sure as the EISY goes as far as checking the Subcategory number. Others here should have more information in using it.

The modules you are controlling. Have their own link databases in them. Including the PLM's six digit id. So messages from it will be processed. Even if the PLM database is empty. Messages sent back may not be seen if the database is empty or does not have the senders ID in it. Power cycling a few times sometimes temporarily let the PLM function again. It will not last for a long time before again stopping to function. 02 69 15 message looks like it was a 15 NAK. Either unrecognized command, end of populated database found. I believe you thought you may have heard a cracking. In my electronics servicing. Sometime a capacitor my crackle as it pops it safety vent as the capacitor is failing. Sometimes even letting out the magic smoke.😀

The ISY9941 does not use the DB9 to network style connector cable in the box. It uses a standard network cable between the units and it has serial signals on it not a typical network signals.

Yes it is different. The 2413S has a Network cable doing Serial communications. I would use the accessory EISY cable. Using some other USB adapter will not have the needed signal pin outs to work. Now if you used a USB serial adapter and the serial cable in the 2413S box. That should work. Though most users never found the cable in the box and accidentally tossed it with the 2413S's box.

Do you have the older 2412S PLM? If you do is your ISY controller powered by a wall wart? The 2412S PLM had power on the cable between the PLM and controller. The presently sold 2413S PLM does not have that power. So it needs a wall wart supply if you do not have one now. Checked the Insteon site and the 2413S is in stock.

You have to wake up motion sensors before you can access them to make changes. As they go into power saving sleep. If you have the motion sensors model number and need the users manuals. Post them and we maybe able to help.

V2.4 has the later capacitors and new serial port board. Including the better serial port interface chip and protection on the two serial interface signals.

Yes as the ISY994i is discontinued. All things like add PRO are no longer available.

From the above thread. With no PRO module added. Your limits are much lower. Posted October 12, 2019 The sales page shows. The ISY994i has Max Nodes 254, Max Programs 300. Pro models Max Nodes 1023, Max Programs 1024. The early 2412S link database is like 417 links later 2412S was ~2000 but 800 was what most found before a time out was caused. 2413S is 1000.

FYI The Range Extender is actually a 2457D3 Lamplinc with the dimmer parts not installed. Just for a quick fun. Look at the FCC Number on the Range Extender and your Lamplinc. It will be the same. It may be a device on the effected electrical box. Making power line noise or is a signal sucker and killing the power line signal but the RF maybe still functioning. https://cache.insteon.com/pdf/2992-222-us.pdf
