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

Like the Access Point devices. You do not physically link them into your ISY994i. They just process Insteon messages and resend them back into the system. You can use the built in Communications aka the 4 Tap. To see how it is working with modules.

I also have an ELK ESM1 that shows thing like noise. Also a JV Digital XTBM X10 meter that shows noise and Insteon shows as a corrupt X10 Message. Also built a Oscilloscope adapter ELA posted here. Used an X10 phase coupler with Isolated winding. One was on 120VAC input and the other side was used to output to a scope.

Thank you for doing the tests and reporting the findings. I did something similar on a 2412S power line only PLM. The noise making device is not too uncommon. I started with X10 and we saw similar things there too. The Config File missing has been reported here. The new PLM is probably fine but there is an error in one of the configuration file entries. Maybe helpful to you at sometime. The Access Points where made using two different base boards. Any of the V1 where on the Powerlinc board and worked well. The V2 that also worked well but where built using the same base board as in the 2413 PLM and subject to the same capacitor failures. I had to rebuild both of my V2 Access Points with better replacement capacitors.

I have information on a V2.75 (417 Links) and a V2.9 (2016 Links). I do not have any V2.8 unit to look at. So I can not say if it is the small or large Link Memory.

Yes the 2412S did have a DB9 to RJ45 cable. In the packing material and many tossed it not knowing it was in the box. You would have to convert the DB9 end to USB and double check you got the correct connections. On a USB converter as the serial pins are not the typical DB9 pin out. The eisy serial cable is still the safest. May be the user can give us the revision number on the 2412S. So we maybe able to find out if is the original 417 link database or the 2000 link database. On the ISY994i the 2000 link database would start to miss link at ~ 800 links. Theory was memory too slow and the ISY994i timed out.

No do not use a 2412S. It has a slower speed Link Database and depending on age a 417 Link Database size. It also has a unregulated +12VDC usually close to +18VDC on one of the PLM interface connector.

Near the bottom of the announcement page. It says due to the limited memory space in a Polisy. It is not known if it will be available for that model. Still being evaluated. Hopefully they can get it working for Polisy owners also.

I would second try a power supply. They are known to be a failure for some of us.

You said you factory reset the PLM. So it was cleaned out of all information and you had to restore all the data.

If your system has Insteon modules. The eisy requires a USB 2413U or the serial PLM you are now using for your ISY994i with the UDI custom serial interface cable. I don't use ZWave but I believe you need an added device connected to the eisy.
