The same as one ends up with 3 Lamborghinis one day I guess 
I purchased a used Pro 2019 in 2020;
Next, after certain whiles I:
Purchased a very old thin client to start with Home Assistant;
Purchased Homey Advanced Flow “add-on”;
I ran out of RAM (1GB) or I love too many apps:
Purchased another used Pro 2019 incl. Adv Flow. to run more apps;
Last year I won a Pro 2026 
Now both 2019s mostly serve as 433MHz antennas because the 2026 has, well, NOT got a wider range 
They also serve as solar surplus indicators (green & red LED ring) @ daytime, and candles @ night using the “Sparkle - Orange” screensaver animation, available per
LED Ring collection app
I also use these 2019s as test Homey for playing around with new apps.
Why not ditch 'em?
I think their value is low to zero these days, and they’re still lovely toys.
