How have you arrived at that? I'm a long time Insteon user, but I don't pretend to know everything about them. To write the above post, I took a spare hub that had been factory reset and added devices to it using the methods I posted above. It worked fine.
There's a limitation in that you cannot set the device Ramp Rate (how fast or slow it dims), or the default brightness level from the app as you could conveniently do from the app when their cloud server was still running. But Insteon was designed hardware first, cloud second. It's not actually a cloud dependent system. It's only the development of the 2245-222 hub that started to lean on the cloud more, but as you can see from the example above, there are still workarounds due to the way that Insteon designed their hardware from the beginning, and its X10 roots. You can set Ramp Rate and default dim levels on Insteon devices from each devices, it's just not convenient, especially if it's a buried micro module.
For a more convenient to use way to add devices and adjust each of their custom parameters, I personally have my eye on this solution. I fully intend to keep using my node.js server with Hubitat to control my devices, because it's frankly just better than anything out there. But this Home Assistant panel should give me back the convenient device configuration I'm now lacking (but honestly not desperately in need of right now).
To be frank, there's a lot of unnecessary panic out there right now. I just pulled Insteon from my old home and actually expanded it in my new home, adding three new dimmers to my setup. Insteon rivals the really expensive Lutron RA2 devices on a lot of levels. I'm not saying it's better, but if you already own Insteon devices, you have some really nice equipment that was a fraction of what it would cost to get similar results with Lutron RA2. Yes, Insteon as a company is now gone, but I'm still using lots of devices from other manufactures that are no longer made, or the company is no longer in existence. Many of us here are. If you can still configure it, and it still functions, why would anyone replace it? Honestly the throw it in landfill mentality is wrong and a pointless waste of money, time and resources.
