MDNS analysis:

not active by default
device starts sending MDNS queries only after one clicks through the myStrom app, device, settings, Apple HomeKit
MDNS is of type hap (Apple Homekit afaik)

Node.js test:

'use strict';
const bonjour = require('bonjour')();

function printObject(o) {
  let out = '';
  Object.getOwnPropertyNames(o).forEach( (name, index) => {
    out += (index > 0 ? ',' : '') + name + '=' + o[name];
  });
  return out;
}

function serviceUpListener(service) {
  if (!service || !service.txt || !service.host) {
    return;
  }
  if (service.host.startsWith('myStrom-Switch')) {
    console.log('MDNS discovered "%s": host=%s, MAC=%s, txt=[%s]', service.name, service.host, service.txt.id, printObject(service.txt));
  }
}

const mdnsBrowser = bonjour.find({ type: 'hap' }, serviceUpListener);
mdnsBrowser.start();

Output (with masked mac addresses):
