d.status() not working

[TheConfax]

The outlet is correctly turning on and off, but d.status() is raising a JSONDecodeError

Traceback (most recent call last): File "C:/Users/theco/Desktop/AA.py", line 11, in <module> data= d.status() File "C:\Users\theco\AppData\Local\Programs\Python\Python39\lib\site-packages\tinytuya\__init__.py", line 502, in status result = json.loads(result) File "C:\Users\theco\AppData\Local\Programs\Python\Python39\lib\json\__init__.py", line 346, in loads return _default_decoder.decode(s) File "C:\Users\theco\AppData\Local\Programs\Python\Python39\lib\json\decoder.py", line 337, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Users\theco\AppData\Local\Programs\Python\Python39\lib\json\decoder.py", line 355, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Any help on this?

Can you paste the code you are using (AA.py)? Based on the error trace, it is getting a null response (None).

Also are you seeing the outlet when you do a scan?:

python -m tinytuya scan

The code is just a simple test:

import tinytuya
LOC_KEY = "local key string"
DEV_ID = "device id string"
IP_ADDR = "192.168.1.9"

d = tinytuya.OutletDevice(DEV_ID,IP_ADDR,LOC_KEY)
d.set_version(3.3)
d.status()

d.turn_off() // d.turn_on() are working regularly.

This is the result of scan in Windows:

Thanks for the tests!

There seems to be some strange behavior with some devices that have a 22 character IDs. I don't know if that is your case. Try adding device22 to the initialization for dev_type:

a = tinytuya.OutletDevice('here_is_my_key', '192.168.1.9', 'secret_key_here', 'device22')
a.set_version(3.3)
data =  a.status()
print(data)

Also, in case it helps, I see you are using a Windows command window instead of a powershell terminal. Tinytuya sends terminal color codes that don't show up in command windows, but you can disable color codes:

python -m tinytuya scan -nocolor      

If you can, I would also recommend pulling the local key again and let tinytuya run a scan on the device as well:

python -m tinytuya wizard -nocolor      

Finally, if none of that helps, make sure there isn't a firmware update for the device (I have seem some odd tuya behavior on early 3.3 devices).

The wizard produced the same local key as before, but my device has indeed a 22 character id. By using "device22" the error changed into this:

Traceback (most recent call last):
  File "C:\Users\theco\Desktop\SS Off.pyw", line 10, in <module>
    data =  d.status()
  File "C:\Users\theco\AppData\Local\Programs\Python\Python39\lib\site-packages\tinytuya\__init__.py", line 467, in status
    payload = self.generate_payload(DP_QUERY)
  File "C:\Users\theco\AppData\Local\Programs\Python\Python39\lib\site-packages\tinytuya\__init__.py", line 410, in generate_payload
    json_data['dps'] = self.dpsUsed
AttributeError: 'OutletDevice' object has no attribute 'dpsUsed'

I don't know if could be useful to you, but by using the tuyapy module I am able to retrieve the on/off status correctly (that module is using the cloud based approach though).

[jasonacox]

Ah! That's encouraging result. I left out a line, try this (notice set_dpsUsed):

a = tinytuya.OutletDevice('here_is_my_key', '192.168.1.9', 'secret_key_here', 'device22')
a.set_version(3.3)
a.set_dpsUsed({"1": None})
data =  a.status()
print(data)

I need to add code to the library to automatically try device22 specifics for those edge-case devices. It's on my list. ;)

Solved! 🎉🎉
Thank you for your help Jason, I'm really a beginner at Python but maybe you could add remarks to 22 characters id and dps & 22 edits to the main guide, that could have been useful!
