What you have is a 4 way switch. It has two 3way and one 4way switch. You just need one 3way switch to control the light with ST and Echo. I use Tp link Kasa Wifi Smart 3way Switch, I can control it with both ST and Echo. Easy to install and setup. Comes in pack of 2.
We don’t recommend using our switches with tube lights since they can draw up to 40 times the power they’re rated for at start-up and that can easily damage the electronics in smart switches. If you had LEDs in the tube fixtures instead and they were under a 100 W, you could use either the ZEN26 or the ZEN21 here.
