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.
