Smart lock Tuya X7

The Smart lock Tuya X7: unboxing, installation and configuration. Fingerprint, code, card and key access.

The Wi-Fi door lock put to the test

Everything you need to know about features, reliability and little tricks. Home Assistant is not supported – but it’s not really needed either. If you have Home Assistant connected to Google Home, for example, you can also control the lock via Google Home. It also works with Alexa and others.

This article on the Tuya X7 door lock is deliberately short. It would be pointless to repeat in detail here what is shown in the video. So, it’s best to watch the video directly 👍
