Missing Power Data
alexandergeiler opened this issue · 11 comments
Hi,
I used your python scripts to get data from an Tuya Smart Meter ZMAi-90.
see:
https://www.aliexpress.com/item/1005001992720359.html?spm=a2g0o.productlist.0.0.2fa2390aiu3hRi&algo_pvid=5cf56e5a-8bd7-4397-a57c-5a7a4deb7086&algo_expid=5cf56e5a-8bd7-4397-a57c-5a7a4deb7086-0&btsid=2100bb5116157546307118257ea49c&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
I can find it
python tuyapower

But I can not get the data from it:

Could I somehow get the RAW JSON data?

Hi @alexandergeiler - all 3.3 devices will require that you have a valid device KEY. If you don't have that yet, you can get the key using the setup wizard in tinytuya (see here).
If you already have a valid device KEY, I recommend you turn on debugging and it will show you the raw payloads. Try this from inside python:
import tinytuya
tinytuya.set_debug(True) # Turn on Debug - for non-ANSI color use tinytuya.set_debug(True, False)
a = tinytuya.OutletDevice('bf3941cb7c91ced1a3mgyx', '192.168.185.32', DEVICEKEY)
a.set_version(3.3)
data = a.status()
print(data)I notice the device has 22 characters. There are some devices that require different command. TinyTuya which TuyaPower uses, should auto-detect device22 but it may not be working correctly. You can try this:
import tinytuya
tinytuya.set_debug(True) # Turn on Debug - for non-ANSI color use tinytuya.set_debug(True, False)
a = tinytuya.OutletDevice('bf3941cb7c91ced1a3mgyx', '192.168.185.32', DEVICEKEY, 'device22')
a.set_version(3.3)
a.set_dpsUsed({"1": None}) # This needs to be a valid datapoint on the device - 1 usually safe
data = a.status()
print(data)Hi,
I got the data with both commands:

It is behaving like the DEVICEKEY is not valid.
What do you see with:
python -m tinytuya wizard
Hi,
I see the following:
python -m tinytuya wizard

I have copied the deviceID and API details from the Tuya web page at https://iot.tuya.com/
see picture:
From what I can tell, you are successful in getting an OAuth token based on the secret. However it is getting an empty result when trying to pull the device list based on the sample bf3941cb7c91ced1a3mgyx device ID you provided.
This is the area getting a no 'result' response:
# Get UID from sample Device ID
uri = 'devices/%s' % DEVICEID
response_dict = tuyaPlatform(REGION, KEY, SECRET, uri, token)
uid = response_dict['result']['uid']Can you confirm that you see your device ID bf3941cb7c91ced1a3mgyx in the iot.tuya.com portal?
Under your Test project you should see Device Management section and a "Details >" link. If you click on that and select the region ("eu") it should show your list of devices.
If this doesn't help, I'll upload additional debugging code to wizard.py to help troubleshoot (it is on my list anyway).
Possibly better... just got this: jasonacox/tinytuya#38
I updated the instructions based on this...
- Set up a Tuya Account:
- Create a Tuya Developer account on iot.tuya.com and log in.
- Click on "Cloud" icon -> Create a project (remember the Authorization Key: API ID and Secret for below)
- Click on "Cloud" icon -> select your project -> Project Overview -> Linked Device -> Link devices by App Account (tab)
- Click 'Add App Account' and it will display a QR code. Scan the QR code with the Smart Life app on your Phone (see step 1 above) by going to the "Me" tab in the Smart Life app and clicking on the QR code button [..] in the upper right hand corner of the app. When you scan the QR code, it will link all of the devices registered in your "Smart Life" app into your Tuya IoT project.
- IMPORTANT Under "API Management" -> "API Products" and ensure the API groups have status "Subscribed": Smart Home Devices Management, Authorization and Smart Home Family Management (see screenshot here) - Make sure you authorize your Project to use these 3 API groups:
- Click each of the API boxes
- Click "Projects" tab
- Click "New Authorization" button
- Select your Project from the dropdown and click OK (see screenshot here)
@jasonacox , thank you for your hint. I haven´t authorizied my API!
I changed this already an hour ago, but it is still not working.

I added some more picture from the iot.tuya.com webpage.
I saw, that I am not able to test the API via the API explorer. May be that could explain the issue.
If I test the API via the DataCenter at China I am getting a "permission deny" error.
If I test the same API via the DataCenter at EU I see nothing... (Response is emtpy)
Thanks!
I think I may see the problem. Your device key is too long. It should be 16 characters, at least I have never seen anything longer than that.
Are you able to get information from the device using the SmartLife app?
If you run the wizard, it should create a devices.json file that has the ID and KEY:
python -m tinytuya wizard
examples devices.json
[
{
"name": "Living Room",
"id": "01234567891234567890",
"key": "0123456789abcdef"
}
]hi,
you are right, I was stupid. I used the Access Secret/Client Secret instead of the Device KEYs.
Sorry for that and thank you for you help!!!
