Controlling servos

ESPHome
1

Hey all ESP homies (get it? :slight_smile: )

I’m working on a robot garage for my vacuum. It’s based on this design but I’m having some major issues.

So I reverted just to create Proof-of-concept first, so I followed this guide. However, when I call the service through the developer tools I get this error:

Failed to call service esphome.livingroomgarage_control_servo. Unknown error

It seems to be the same whether or not the controller is on or off. What am I missing here?

Hardware:
JCPower 5v 10A power supply
MG996R servos
NodeMCU

I use this wiring;
