Must be http post to /power

webServer.on("/power", HTTP_POST, []() {
    String value = webServer.arg("value");
    setPower(value.toInt());
    sendInt(power);
  });

I do not understand you, what do I need to do?

If you access in browser that url path you perform HTTP GET request. If you want to control the power remotely you need HTTP POST request. Ex: curl -X POST http://esp_ip/power
