json obj data unvalid about node-red-contrib-tuya-smart-device HOT 7 CLOSED

I see mispelling of the dps parameter in your code.

dsp: 19

Lets wait for the release of tuyapi with the fix. Once it is ready I will patch this node. 👍

from node-red-contrib-tuya-smart-device.

This is a known issue with some devices to query the exact status codetheweb/tuyapi#77

But you will be able to get the events associated with the device.

I am trying to find some alternatives.

Hope the set command is working fine :)

@AymanFadda Can you please confirm the fimware version of the device ?

Got to Tuya app-> choose the device -> edit -> Select the "Check for firmware update at the bottom"

from node-red-contrib-tuya-smart-device.

Hi. The firmware version is 1.4.2 both for main module and MCU module.
Thanks

This is a know issue with the tuya library on some devices.

More details about the issue can be found at codetheweb/tuyapi#338

Once it is fixed, we can bring the changes here.

Meanwhile i found a trick to resolve this issue partially .

Make the IP of the device static, and block all TCP/UDP connections above 6670 port from this IP. ( You router should support port blocking) . This prevents the cloud communication of the device. the json unvalid error has to do some thing with the communication with the tuya cloud api. so we are blocking it. Now only using the node we will be able to control the device. The app has no use now. You can disable to the port blocking and re connect the device to configure it via the app.

Once getting the response as null , hit a get request for dps 11( in my case it is the timer ) and value as 0. subsequent get calls wont give the json error. But it will return only the status of the 11 dps until some one issues a power on / off command.

Here is the flow for your reference

Closing the issue as this is not a bug with this library

I see mispelling of the dps parameter in your code.

Thank you Juampe. with both dsp or dps it's not working. As vinodsr said, it must be a problem in the API of Tuya.
