Smart home has low pass rate of turning on multiple devices

[ssoto2]

Currently, have FireTV Cube and Echo. The smart home is connected with TP-Link Kasa App. In my office, there is 3 lights setup. One tp-link plug into a lamp (HS-105) and two tp-link bulbs (LB-130). Amazon Echo is very good turning on these 3 lights individually. When it comes to turning on all the light at once the echo is about 1 in 15. To make it more of a pain, often it will turn all the light on and immediately back off except for 1 of the 3. In the house, there is a google home hub and complete the same task always.
