How can I communicate wirelessly through my windows with devices outside? Is there a <a href="https://fosstodon.org/tags/transducer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>transducer</span></a> available e.g. radio to <a href="https://fosstodon.org/tags/optical" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>optical</span></a> to <a href="https://fosstodon.org/tags/radio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>radio</span></a> ?
