LOCAL control of Tuya devices

kap · January 12, 2019, 9:38pm

Anyone doing LOCAL control of Tuya devices in a recent home assistant build, say 0.84 or later? I got the cloud based version working fine, but would prefer not to rely on Tuya servers or allow these devices to have wan access.

I see a number of posts from before the official Tuya component came out, and tried unsuccessfully to use some of those configs. I do have my device IDs and local keys already. Just need (working) hass config info. I also have a copy of tuya.py but no idea if the one I have is the right version if it is still needed at all.

Yes works well here, however, there’s some development in the works to be able to flash tuya stuff to tasmota OTA, if that interests you. A rough version is released but wait a week or so if you can for it to get polished. Somewhere along the way someone had some modifications to their tuya.py that picked up the device without specific IP address.

I’ll be ditching this as fast as possible once I get ESPhome on them without haveing to crack them open.

I did my tuya local like this in config.yaml

switch:
  - platform: tuya
    host: 0.0.0.0
    local_key: ...
    device_id: ....
    switches:
      switch1:
        friendly_name:  Christmas Tree
        id: 1

Yeah if you can hold out I would. It’s not that it’s hard to setup the local control, it’ll just be so much better if we can flash them to tasmota.
If you still want to get it setup this will get you there.

Both methods below require you to install the CLI tool before proceeding.

Install it by running `npm i @tuyapi/cli -g`. If it returns an error, you may need to prefix the command with `sudo`. (Tip: using `sudo` to install global packages is not considered best practice. See [this NPM article](https://docs.npmjs.com/getting-started/fixing-npm-permissions) for some help.)

## Linking a Tuya device with Smart Link

This method requires you to create a developer account on [iot.tuya.com](https://iot.tuya.com).

It doesn't matter if the device(s) are currently registered in the Tuya app or not.

1. After you've created a new account, click "Cloud Development" in the top nav bar and click "Create".  After you've created a new application, click into it.  The access ID and access key are equivalent to the API key and API secret values need.)
2. Go to App Service > App SDK.  Click on "Obtain SDK", select the WiFi option, and enter whatever you want for the package names and channel ID (for the Android package name, you must enter a string begining with `com.`).
3. Take note of the **Channel ID** after saving.  This is equivalent to the `schema` value needed.  Ignore the app key and app secret values.
4. Go back to Cloud Development -> the application you created earlier, and select "Linked Device" on the left. Then click on the "Linked Devices added through app distribution" tab, and select "Add Apps".  Add the app you just created, and click "Ok".
5. Put your devices into linking mode.  This process is specific to each type of device, find instructions in the Tuya Smart app. Usually this consists of turning it on and off several times or holding down a button.
6. On the command line, run something similar to `tuya-cli link --api-key <your api key> --api-secret <your api secret> --schema <your-schema/channel ID> --ssid <your WiFi name> --password <your WiFi password> --region us`.  For the region parameter, choose the two-letter country code from `us`, `eu`, and `cn` that is geographically closest to you.
7. Your devices should link in under a minute and the parameters required to control them will be printed out to the console.

This does work just fine with the Linux subsystem in Windows 10 if you don’t have a Linux box.

Ok, being able to flash to tasmota sounds like a winner to me - I will wait and keep an eye out for developments on that. Thanks.

Could you share a copy of the tuya.py custom component file please. Can’t find it anywhere

Cheers
