220-240V remote controlled outlet for NEMA 5-20 possible?

My stereo amplifier is made for 220-240V current so I had an electrician combine 2 brakers like they do for dryers or ovens. The outlet this plugs into is of the NEMA 5-20 type. The amp's power consumption is 400W. Wondering if there's a device I can use between my amp and the outlet to wirelessly power it on or off. It has a mechanical switch that I can leave set to "ON" permanently and the idea would be to use a remote to turn it on/off to prevent needing to kneel down every time to do so (as I have bad knees).

I've used this on a 120V DAC which works perfectly but it's the wrong plug, the wrong voltage, definitely wouldn't be able to handle the load, etc.

Looking for either a device that could do this or any suggestions on how to accomplish this.

The closest I was able to find is this.

My guess is it's terminated with the same North-American NEMA 5-15 so I'd need a 5-15 to 5-20 converter that can withstand the load... and I'm unsure if it's safe to do so and whether there's a smarter/better way of doing this.

You could just use a cheapo Wifi Power strip - https://www.amazon.ca/LINGANZH-Protecto ... 07D57DL9F/ - works with both 110 & 220v
This strip uses the wrong NEMA type so I couldn't use it, hence the challenge in finding something for the appropriate type. I nevertheless thank you for your suggestion.

In that case i’d suggest swapping out the plug. Its safer than using an adapter imo

other option if you can't find a wireless one is to buy a extension cord with a mechanical switch and mounting it higher.
