My smarthome life began in 2015 when my brother gave me the original echo dot as a bday gift and apologized to my wife all in the same motion lol.
The very first device I bought was a Logitech Harmony Hub. I've owned Harmony products for two decades. I recall my wife being shocked at the price tag for 'just a remote control' back in 2002 lol.
In six years my entire smart home has received several upgrades. My own joke is that I'm on version 5.2. The one device that stays strong is the Harmony Hub. Unless I'm upgrading an AV device I never think about the Harmony Hub. I rarely ever have to tinker with it. The only time i do is when we lose power it has a habit of connecting to the Velop node furthest away. A quick unplug and reboot always fixes it. It's a terrible device when your wifi SSID changes but it's manageable.
So now with them shutting down and no viable replacement I do get a bit concerned. Sure they say it'll be a long time before they shut down their servers... but we learned with ST app and IDE that a long time is about 3 years. I figure I have 3 years to figure out a decent replacement. Thing is a lot my devices are connected. So like with my big screen and Chromecast with GTV i can likely just integrate them into my own automations. However I still have a PS4, which really doesn't work well with the Harmony either.
I really don't feel like buying a new AVR as I just bought one. I would've searched for one more connected if I knew this was coming.
I really hope someone either offers to buy the Harmony brand and bring it to 2021, putting a new spin on it or someone steps up to fill their shoes.
