SwitchBot button pusher is almost half off at Amazon, down to $20.01.
You will need their mini hub for integration with SmartThings. That’s also on sale, at $27.
The buttons are Bluetooth to the mini hub, then the hub is WiFi to the internet and cloud to cloud to ST.
I use these in my own home to retrofit some dumb devices, including a mini blender and the eject button on the DVD player. I wrote a review for this forum in 2020.
