How can get statistic from Smart Plug?

[EugeneRymarev]

Hello everyone!
I have many Smart Plugs.
I want to collect statistics from them.
How can this be implemented?
Where can I find an example to work with them?
Preferably via API, but LAN is also possible.

Do I need to connect my Smart Plugs to a Developer Account?

Hi @EugeneRymarev -

• LAN access: To get the statistics (status) of those Tuya smartplugs over LAN you will need the device LocalKey.
• Cloud API access: To get statistics via the Tuya Cloud you will need to set up an IoT account.

For both, that requires that you register them with the Smart Life App or Tuya Smart App and to set up an IoT account with Tuya.. See the setup instructions: https://github.com/jasonacox/tinytuya#tuya-device-preparation

LAN

    import tinytuya

    d = tinytuya.OutletDevice('DEVICE_ID_HERE', 'IP_ADDRESS_HERE', 'LOCAL_KEY_HERE')
    d.set_version(3.3)
    data = d.status() 
    print('set_status() result %r' % data)

CloudAPI

import tinytuya

# Connect to Tuya Cloud
# c = tinytuya.Cloud()  # uses tinytuya.json 
c = tinytuya.Cloud(
        apiRegion="us", 
        apiKey="xxxxxxxxxxxxxxxxxxxx", 
        apiSecret="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", 
        apiDeviceID="xxxxxxxxxxxxxxxxxxID")

# Display list of devices
devices = c.getdevices()
print("Device List: %r" % devices)

# Select a Device ID to Test
id = "xxxxxxxxxxxxxxxxxxID"

# Display Status of Device
result = c.getstatus(id)
print("Status of device:\n", result)

I know you are not manager of Tuya IoT, but i can't download IoT Device Manager APK. Can you upload it here or give me link?
Link from QR code Access Denied

[jasonacox]

Hi @EugeneRymarev - You should not need the Device Manager APK. You should be able to connect your devices and link your IoT account with the "Smart Life" App - Here: https://play.google.com/store/apps/details?id=com.tuya.smartlife

You will use that app to scan the QR code on the iot.tuya.com website per STEP 3 on the instructions which will connect your devices to the IoT account you create.

[EugeneRymarev]

Yes, Smart Life application is now linked.
But how can i link digma smart life - i use this app, because at first setup i install it.
Or maybe you know easy way to transfer devices from digma app to smart life app?
This apps almost same just another design, but works with same protocols.

When i scan QR with Digma App i always receive in Tuya "QR code has expired" in web.

[EugeneRymarev]

Nevermind. For now i can't use Tuya API because it's not free.
I apologize for the disturbance.

[jasonacox]

Hi @EugeneRymarev - what is not free? I haven't paid for anything to use the Tuya API. Are you looking at their commercial offerings instead of the free trial option?

Also, on the screenshot. Thanks for that feedback. What this the process you tried?

[EugeneRymarev]

This QR code is right for Smart Life App.

c.getdevices().devices gives me this error

Device List: {'Error': 'Error Response from Tuya Cloud', 'Err': '913', 'Payload': 'Unable to get device list'}

c.getstatus(id_) gives me this error

Status of device:
 {'code': 28841101, 'msg': 'No permissions. This API is not subscribed.', 'success': False, 't': 1645763611021, 'tid': '15ad2e8195f411ecb018e66f3a529df6'}

To subscribe need to pay.

[jasonacox]

Thanks for the information. When you set it up, did you select the free API option?

I created a PDF of the screenshots to set up... is this similar to what you did?

Tuya IoT API Setup.pdf

[EugeneRymarev]

I create project again and now all works correctly. Thanks.

[jasonacox]

That's great news! Did you follow the PDF steps I sent? If so, should I add a link to the README setup instruction to those slides?

[EugeneRymarev]

Yes, but that same steps, like i do earlier.

Another question:

How can i receive statistics from smart plug? Not see this in Cloud class

[jasonacox]

Thank you!

I updated this slide:

And the PDF:
Tuya IoT API Setup.pdf

The power metrics should show up in the status() or getdps() responses:

# Display Status of Device
result = c.getstatus(id)
print("Status of device: %r\n" % result)

# Display Data Points (DPS)
result = c.getdps(id)
print("DPS: %r\n" % result)

[EugeneRymarev]

The power metrics should show up in the status() or getdps() responses

That's all what i receive. This information does not contain the statistics I need.

[jasonacox]

I'm sorry, I misunderstood. If you are looking for current state, voltage (V), current (amps) and power (W), that data you got from getstatus(id) should work.

If you are wanting to access historical power data (kWh), I'm afraid I haven't figured that out. You can look at https://iot.tuya.com/cloud/explorer to see if you can find the right API call that would have that payload. Let me know if you find it and I can add that to TinyTuya.

i can't get "Electric today (kWh)" from cloud and also not locally.
Add_ele (DPS 17) is something else. I suppose it is energy consumed between 2 updates. not sure.
No any way to get "Electric today (kWh)" as see on APK?
