Cant get this flow working
I have a tuya socket device and want to get the usage in domoticz
Cant find the solution maybe someone can help me?
This is the flow:

Code: Select all

What exactly do you want?
To send some data in Domoticz?

Do you have mqtt broker installed?

More information please

Posted: **Sunday 12 October 2025 13:04**

I want the kwh from that socket and maybe later some more values
Yes i have a mqtt broker
And want to do it with node red

Hello @edwin1234,

I have loaded your flow from your first post in my test system.

I do not have any Tuya devices, so I can´t get the Tuya-local node connected to a device.

First question:

Why do you use

node-red-contrib-tuya-local

This node has been last updated 5 years and 5 month ago?
See: https://flows.nodered.org/node/node-red ... 3cYxQ0budG

I think: https://flows.nodered.org/node/node-red ... ya-devices, is newer and so more up to date.

If I look to your picture of the debug pane, I see that the data has been presented in e.g the key

Code: Select all

msg.payload.dps.1

However in your "Switch" node, I see that you split your objects, based on the key:

Code: Select all

msg.payload.data.dps

That does not match, with your picture. Where does "data" come from?

You use this in the Function node as well.

Have a look

Regards

Hi firewizard,
The data is a debug node connected to the tuya socket. Where alle .dps is written. See photo

Hello @edwin1234,

The data is a debug node connected to the tuya socket. Where alle .dps is written. See photo

I know, but I mean that you have an object, called data

Open the "Switch" node:

: Screenshot_switch_node_edwin.png (40.82 KiB) Viewed 319 times

Your selection property is: msg.payload.data.dps.
"data" is not shown in the debug pane.

Heve a check

viewtopic.php?p=323545#p323545

There you can find two different solutions - to use http or mqtt

Posted: **Sunday 12 October 2025 16:06**

@habahabahaba,

In the picture, you can see that Edwin has chosen for MQTT and not HTTP.

@FireWizard , hi.

No i dont see that he chosen mqtt... Where did you see that?

Anyway, its better to have a choice.

Hi firewizard i copied the switch node from another tuya device (not a socket)and that flow is working and there is no data.dps as far as i can see.
But im still a noob at this so i dont understand why “ koelkast “ is not working.

And where do you see : msg.payload.dps.1

You sad: I look to your picture of the debug pane, I see that the data has been presented in e.g the key
CODE: SELECT ALL
msg.payload.dps.1

What should the property line be to make it working?

Posted: **Monday 13 October 2025 19:07**

Hi,

@habahabahaba,

You asked:

No i don't see that he chosen mqtt... Where did you see that?

If you go to the picture of the flow, you will see, at the far right side, a purple node, called "To Domoticz"
If you are a little familiar with Node-RED, you recognize the type of the node.
The MQTT nodes, looks like:

: Screenshot_MQTT_In_Out_node.png (2.47 KiB) Viewed 276 times

Honestly said, @edwin1234 copied this from another flow. With that other flow, I supported him.
So I recognized this flow.

Alright

@edwin1234

You asked:

And where do you see : msg.payload.dps.1

This is a combination of observations in your debug node.

: Screenshot_debug_Tuya.png (94.53 KiB) Viewed 276 times

Node-RED sends always an object to the next node and mostly this object is in msg.payload
This is also here. msg.payload is an object.
If you press the "triangle", it will show you the contents of the object. In this case it is devId and dps.
The devId you can safely ignore. The other part is dps, which is also an object.
Press the "triangle" and it will show the contents.
In this case a number of keys (1, 9,18,19,20, etc)

The Tuya protocol works with dps, which stands for DataPointS.
To find the Tuya data-points, look at: https://developer.tuya.com/en/docs/iot/ ... g4x1dt7a6j
or for Local Tuya: https://github.com/dulfer/localtuya-device-datapoints

So at the end the key is : msg.payload.dps.1 or msg.payload.dps.9, etc

You can find that path very easily, by hovering with your mouse over the buttons after each line.
See: https://nodered.org/docs/user-guide/messages

So to solve your issue:

In the Switch node: Change the property msg.payload.data.dps into msg.payload.dps
Do the same in "Function 4"node. Change msg.payload = { "command": "udevice", "idx": 2710, "nvalue": parseInt (msg.payload.data.dps["20"]/10)} into
msg.payload = { "command": "udevice", "idx": 2710, "nvalue": parseInt (msg.payload.dps["20"]/10)}

But I do not expect this to work. Which data (dps) do you want from your "Koelkast" to send to Domoticz?
Which type of sensor are you going to use?

Let us know and we can help you.

Regards

@FireWizard , yes, you are right.
I missed it

Posted: **Monday 13 October 2025 19:21**

Thank you firewizard,
I want the power to send to domoticz and i think its dps 20 and send it to a general kwh device.

Posted: **Monday 13 October 2025 19:37**

Hi @edwin1234,

You said:

I want the power to send to domoticz and i think its dps 20 and send it to a general kwh device.

Is that the only data, you want from the "Koelkast"
You think, it is 20, are you sure? Could it be 19?

In the links, I included in my previous post, 19 = power and 20 = voltage.
Can you check that?

Regards

Posted: **Monday 13 October 2025 19:54**

I think youre right it is 19

Posted: **Tuesday 14 October 2025 12:33**

Hello @edwin1234,

I have created a simulation for the Tuya node and tested the complete flow with Domoticz.

I assume that for "Power" the DataPoint is 19 and that the value has to be divided by 10.
At least that make sense, so the power usage of your refrigerator is 101.2 W.

: Screenshot_Refrigerator_Power.png (43.14 KiB) Viewed 252 times

The most simple flow is as follows:

: Screenshot_Tuya_flow.png (13.94 KiB) Viewed 252 times

Do as follows:

1. Create a virtual device, type Electric (Usage + Counter) in Domoticz
2. Click "Edit" and set "Energy read" to "Computed"
3. Replace the "inject" node, with your Tuya node.
4. Replace the MQTT output node with your own MQTT output node
4. If everything is working fine, remove the debug nodes. I assumed that the index of your device in Domoticz is 2710.

The flow:
