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.

With world trade uncertainty these days. We have no idea on when the new PLM maybe seen, if ever. I just went to the Insteon sales site and no mention of it. Also the 2413U USB PLM is out of stock with an expected receiving more date is October 2025.

Can not say what they have in development. There was some information on the Insteon.com. By the present owners on a new PLM was in the works. I can say the one developed by the previous owners and was in the FCC Database. 2234-222 USB,2234-223 Serial. Are not anywhere close to the present 2413S/U PLM. Completely different case closer to what the 2457D3 is in size, more universal power, more faster and sized link database. The back side has a separate AC connector panel that looked like it could be changed to other countries power standards.

My NVG448BQ installed by Frontier. Was laying on its side and was getting very warm and even smelled hot. The information on the ARRIS web site said it should not be laying on it side as it has ventilation slots on both side. I mounted mine vertically as the installation sheet said. It it is now just slightly warm.

Some brand and model LED lights don't work well on Insteon dimmers. Some here have found certain bulb models work better. Quick test only. If you still have an incandescent bulb around. Try replacing one of the bulbs and see if they work better. Some information from Insteon that may assist you. https://www.insteon.com/products/led-flicker-glow-eliminator https://support.insteon.com/support-knowledgebase/get-started-led-filter Those networks are also available from other sources and the manufacturers data is easily seen on the page in the link.

I was fortunate. During the period when the USY994i was supported and you could still add plugin modules. I add the ones in my original ISY994i to a a spare base ISY994i. They are linked to the UUID.

The LED observation. Was the original power supply and the replacement fixed it? If so my supply on the ISY994i did act similar when it started dying.

I agree. I have had a few myself. From old ISY44i and ISY994i. With one. The ISY994i was OK until I did a power cycle on it. Then all it did was start to reboot and the supply shut down and the cycle repeated. One nice thing was the ISY994i has a wide power input range, Mine where originally 5V 500ma and 5 volt 1 amp. Now I have 12V one amp.

Pro was an ISY994i add on. It added more link database size and the ability to disable automatic update wries to modules or just wireless devices so you could wake them up individually. So they didn't possibly interfere with each other. I believe that feature is standard in the eisy with no add on needed.

Yes. The pro add on. Let you delay writes completely or just to RF only devices. That allowed you to wake up each device and then write the updates to that device alone.

It also has to be a USB 2413U or the 2413S from the ISY9941 and the USB to serial adapter cable. With the special wiring sold by UDI.

Is the old one a 2413S or 2413U? Not well up on the Polisy I vaguely remember it could also use a 2413S serial. The eisy is USB so you need a 2413U or the specially made USB to serial UDI cable UDI has available.

Glad you found it and it is not an uncommon thing to happen. Some stickers where harder than others.
