Insteon system replacement

Hi Reddit,

I just moved, and my new house is using Insteon. The most used light switches are Insteon switches, and there are about a dozen of them.

I confirmed with the previous owner, and there is no hub. I confirmed with my searches that the system works on its own without a hub, but without the hub, the configuration can't be changed.

My goal is to replace a few broken switches, and change the programming of others. For that, I would have to buy stuff. I see that the Insteon company suffered instability in 2022, and I'm not comfortable with investing in this technology, for whom the future might be unstable.

I'm looking to replace Insteon with a different solution that would suits my needs. Do you have ideas what could it be ?

Thanks for the help!
