I`ve designed a little stand for the charger of the Motorola Advisor TPG2200 with space for an Shelly 1 smart switch. You can configure the shelly as an sensor so you can switch on smart devices when the integratet relais.

• You need the following parts extra:
  2 x DC Power Jack-Sockets (5,5 x 2,1mm)

  1 x Shelly 1
  1 x 12v power adapter with DC-Power-Jack (5,5 x 2,1mm)
  1 x DC-Power-Jack (5,5 x 2,1mm) with or without cables
  2 x WAGO 221-413

circuit diagram:

• connect plus from input-dc-socket with one junction box clamp

connect plus from junction box clamp with the shelly (N(+))

• connect minus from input-dc-socket with the other junction box clamp
• connect minus from junction box clamp with the shelly (L(-))

connect minus from junction box clamp with the second dc-socket

• connect the return signal from second dc-socket with the shelly (SW)

shelly/smarthome configuration:
In Shelly-app:

• timer:
  • auto off: I have configured it with 180s (thats enough for me to leave the house. you could configure it in different ways. but this were the easiest way for me)
• settings:
  • eco mode: active
  • power on default: SWITCH
  • Button Type: Activation Switch
• add the shelly device to the assistant. follow the instructions in the app
• then you need to set up two new scenes for you home (not personal)
  • turn on: set the shelly as a trigger. when shelly switches on -> configure you devices / lights to turn on
  • turn off: set the shelly as a trigger. when shelly switches off -> configure you devices / lights to turn off
