Maybe a glut of these will be on eBay soon.
They're already selling out. I sold a box of old devices for profit this week.
I had removed about 20 of them from my last home and never got around to installing them (in-wall) at my new home so I put them on eBay and already made back most of my investment.
The other good thing about, at least the light switches (which is their core product), is that they work without an internet connection and will continue to function.
However unfortunately the less tech savvy users who set up automations through Insteons service will be left (quite literally) in the dark now.
They've been around way longer than most of the "modern" protocols. It was basically Insteon and Lutron in semi-affordable home lighting control space for years and years and years before cloud-controlled IoT and Alexa entered the picture.
I'm really wondering how this all came to pass... guessing they tried and failed to jump on the app/cloud bandwagon? Their new app was late to the game and in beta for, like, two years?
Their Apps relay through the cloud however to avoid the hassle of local network discovery. So the Apps are completely useless now.
Most/all devices and the hub have a pairing button. You can pair devices to each other or the hub still. It's complicated but works, the App also coordinated pairing and was easier but still kinda janky compared to competitors.
Home Assistant can talk to the hub via it's local API and still manage and paired devices. 3rd party hubs like Isy still work just fine.
Because Insteon is no longer making devices, they are now selling for a premium on eBay because people invested in the ecosystem don't need to change.
People like my mom, who only has a hub is 3 devices, are better off selling for profit now and jumping to a new platform. Those using Isy can just keep going as Insteon devices are well made and will continue to function for years or decades.
