ioBroker.tuya

Tests: Linux/Mac/Windows: Windows:

ioBroker adapter to connect to several small and cheap Wifi devices that care connected to the Tuya Cloud and mostly use the Smartlife App/Alexa-Skill. The adapter supports reading real time status updates and controlling of those devices once synced with the respective mobile phone app.

Tuya devices are ESP8266MOD WiFi smart devices from Shenzhen Xenon.

Beside devices usable with the Smart Live App the use of the Jinvoo Smart App, Xenon Smart app, eFamilyCloud, io.e (Luminea or such) app should also be possible. Please report back if successfull.

The adapter is proofed to work very well with all devices that are "always in wifi". Devices that only come online when there is an event, send their data and go offline again are not supported.

One adapter instance can handle all devices in one network that routes UDP packages.

How the adapter works

Basic functionality

The adapter monitors the local network for UDP packets of Tuya (old firmware, so unencrypted only) devices. It is needed that the ioBroker host where the adapter runs on is placed in the same network segment as the devices and UDP multicasting needs to be supported by the router!

All detected devices are added to the adapter and as basis functionality the adapter requests data in the defined polling interval. Without a sync with the respective mobile app (see below) NO further functionality like real time updates or controlling is possible.

Newer encrypted devices will NOT show up before you do a device sync (see next ...)

Advanced functionality after device sync

To get the full functionality of the adapter and also support devices with the new encrypted Firmware an encryption key needs to be known by the adapter.

The easiest way to receive this encryption key is to get them from the used mobile app. To do this the adapter provides a proxy to catch the communication of the app with the tuya servers and grab the needed information.

Important Note for iOS Users: The Proxy approach described here is not working anymore. As soon as you have Smart Life App version 3.10 or higher the communication from App is no longer visible to the proxy. But it still works with all Android App versions, so the best approach is an Androis Emulator as roughly described at https://forum.iobroker.net/topic/23431/aufruf-tuya-adapter-tests-verschl%C3%BCsselte-ger%C3%A4te/19

To do this first of all you need to add a custom Root-Certificate on your mobile device. When you click "Start Proxy" in the adapter instance configuration the certificate is created for your system and shows a QR-Code to the download location. Ideally scan the QR Code with your mobile device and follow the process to add and trust this Root-Certificate. If the QR code location is not reachable (may happen when use Docker or such) then open the "Proxy Web Info Port" in your browser and click on "Root-CA" in the navigation and you can download the CA File too.

Now make sure to close/kill the respective Tuya smart app. After that add the Proxy-Port and the ioBroker host as "Manual" Proxy for your WLAN connection on your mobile phone.

Now open the respective Tuya Smart App and/or reload.

The Admin configuration will show a success message if the relevant data packet was received and will then turn the proxy off 10 seconds later. You can now remove the proxy from your phone and also untrust the certificate.

Directly after this the objects should be updated with more meaningful names and receive live updates from then on automatically and should be able to communicate.

The sync is only needed initially or after you added new devices to your App.

Some images for some mobile OS can be found at the Proxy-Page.

Not for Battery powered devices

Battery powered devices are normally NOT supported by this adapter! The reason is that they are not online all the time to save power. Whenever they get a signal, thay go online, send the update to the the Tuya cloud servers and go offline again. They do not emit any UDP packages or are online long enough so that the adapter could connect to them. A soon as someone finds a way to directly fetch data from the Tuya cloud this may change.

The work of the adapter would not had been possible without the great work of @codetheweb, @kueblc and @NorthernMan54 (https://github.com/codetheweb/tuyapi) and https://github.com/clach04/python-tuya and many more.
