I'd verify that your scenes are set up correctly. More detailed information about your setup would help.

Create a scene where you want all devices to be when fast on command is issued (all devices should be responders) Create program that triggers that scene upon a fast on command.

Many folks on here talk about and use hue. I used to use hue when I used my polisy. I believe it works natively with it now

Go with what Tazman said. You must operate the scene when using the admin console. Using the device itself will only operate that device. What you are experiencing is proper behavior.

Tazman is correct. I didnt read his message close enough. He's activating the secondary switch of a 3way (non-load) instead of the scene itself. Since he's activating the device, he's only controlling that device.

Have you tried File>restore PLM, then File>Restore Devices?

As long as the signal reaches it will work. Just remove the photocell, wire the module in place, and program. I recommend adding the module to your system prior to installing.

Isy or eisy? Isy integration would be zero chance since it's obsolete and no more updates are coming for it. Eisy would be based on a developers interest. While wiz may be big for you, it may not be big enough for the eisy community (developer or udi) to justify the time and effort to develop, maintain, and support a node server for it.

The only benefit would be not needing a plm. It would require a rewrite of insteon code since insteon is not zigbee based. Since you're wanting to use the eisy anyway, there wouldn't be a noticeable difference in performance.

As others have said (and linked to), 5.3.4 is the latest (and last) update for the isy994 due to it being eol.

Insteon doesnt have to support Matter if the eisy supports it. Your devices would talk to other matter devices via the eisy.

You need to decide on 1 controller and 1 method for that controller otherwise you will continue to face the issues you are having. It's akin to having multiple bosses at a job that issuing commands but none of the bosses know about each other and what each other are doing. If your software is doing what you need, then you should stick with that and code for everything else that you want. Otherwise, I'd look at the eisy and portal subscription as an investment that allows you to grow your system exactly the way you want it to be.

Firmware and UI?

Only udi would have that info
