OTA on local Blynk server

well that explains part of it at least.

Anyway I’ve updated the handler and it ‘works’. ‘Works’ because I do not have the equipment to check whether it actually works as intended, but no errors, so it appears to be going smooth.

void ArduinoOTAClass::handle() {
  if (_state == OTA_RUNUPDATE) {
	Serial.print("OTA RAISES WIFI POWER OUTPUT");
	WiFi.setOutputPower(20);
    _runUpdate();
    _state = OTA_IDLE;
  }
}

note that the default for an esp is 20 and if you change it in the code it will change back to the intended value on boot (which happens automatically after OTA) so you only need to set it high.
