Turn on smartplug amplifier with REST API

[supersix]

My amplifier is connected to a Shelly Plug smartplug.
I would like to control its power state automatically, according to Wiim mini playing state, just like a "virtual 12V trigger".
Powering on a Shelly Plug is easy: http://192.168.xxx.xxx/relay/0?turn=on
Powering it off is easy too: http://192.168.xxx.xxx/relay/0?turn=off
Authentication with challenge-response is available too.

Thanks

Many amps have their own 12v triggers, could you not use the amp's trigger to connect to the WiiM?

Another option is to connect both the amp and the WiiM to the shelly plug using an adaptor.

It's a vintage amplifier, so no 12v trigger.

That requires to operate the Shelly app, then the music app, then remember to use the shelly app again to power off the amplifier.
Possible, but definitely more inconvenient than virtual trigger managed by Wiim Mini.

If you are running a script to control your Shelly Plug could you use the same device running the script to continuously query the WiiM state and if it is on turn on the Shelly Plug?

WiiM HTTP API - misc items

Main post updated. And something quite interesting, I think. getStatusEx method of http api returns "PCB_version": "3" for the new unit. For the old one it's "PCB_version": "2". Can you be more specific about how to check this?

In your setup, since you can control you vintage amplifier with a smart plug, you should be able to replace the smart plug with an Audiophonics 12V trigger.

AUDIOPHONICS Trigger 12V 230V Slave Power Supply Device - Audiophonics

The Audiophonics Trigger 12V is the simple and effective solution for turning on and off any appliance connected to 230V AC mains with an IEC female mains input

If your amplifier has a captive power cord you'll need to purchase two power adapter cords to complete the setup.

Here's another option for a voltage controlled power outlet.
