Control Holiday lights - Window candles

I have 10 of these Lights in windows around my house for christmass. Right now they are simple dusk/dawn sensor lights. I’d like to be able to control them remotely via HA if possible. If not does anyone know of any similar candle lights with remote on/off that I can control with HA?

Since it has a cord and plug, how about using a sonoff or similar switch?

I was looking at the sonoff switches. I can get them for about 5$ each would would be nice. But they do require some reprogramming to work with HA.
