Many thanks for the reply!!

Just a detail, to activate protocol V3.3 do I only need to edit the tuyapi/index.js file (by replacing 3.1 by 3.3) ?

is that enough?

I've tried to update the index.js with 3.3 instead of 3.1 but din't change anything...

I still have an OSError when launching the get_dps.py

I don't know where I'm wrong then....

As I've mentioned before

"Then you can add device.set_version(3.3) in the get_dps.py after creating the device and the get_dps.py should work"

But you need pytuya 7.0.4

Hello,
Thanks for the help!

So here is the situation :
I have modified the __init__.py in the pytuya directory to change 3.1 to 3.3 in the " class XenonDevice(object): " which results in "self.version = 3.3".

The get_dps.py was still crashing as follow:

Code: Select all

Traceback (most recent call last):
  File "./get_dps.py", line 46, in <module>
    data = device.status()
  File "/home/pi/domoticz/plugins/Domoticz-Tuya-SmartPlug-Plugin/pytuya/__init__.py", line 279, in status
    payload = self.generate_payload('status')
  File "/home/pi/domoticz/plugins/Domoticz-Tuya-SmartPlug-Plugin/pytuya/__init__.py", line 219, in generate_payload
    json_payload = self.cipher.encrypt(json_payload, False)
  File "/home/pi/domoticz/plugins/Domoticz-Tuya-SmartPlug-Plugin/pytuya/__init__.py", line 64, in encrypt
    cipher = AES.new(self.key, mode=AES.MODE_ECB)
  File "/usr/lib/python3/dist-packages/Crypto/Cipher/AES.py", line 94, in new
    return AESCipher(key, *args, **kwargs)
  File "/usr/lib/python3/dist-packages/Crypto/Cipher/AES.py", line 59, in __init__
    blockalgo.BlockAlgo.__init__(self, _AES, key, *args, **kwargs)
  File "/usr/lib/python3/dist-packages/Crypto/Cipher/blockalgo.py", line 141, in __init__
    self._cipher = factory.new(key, *args, **kwargs)
ValueError: Key cannot be the null string
So I hard coded the local key in :

Code: Select all

class Device(XenonDevice):
    def __init__(self, dev_id, address, local_key=None, dev_type=None):
        super(Device, self).__init__(dev_id, address, 'xxxxxxxxxxxxx', dev_type)
Which succed to give me the DPS of both my plugs and the one of the curtain switch.
Socket : 'dps': {'1': False, '2': 0}
Curtain switch : 'dps': {'1': '3'}

I put it back again to "super(Device, self).__init__(dev_id, address, local_key, dev_type)" and my socket are more or les working on domoticz :
The switches created by the pluggin does not update to reflect socket state, so I created a dummy switch to pilot it.
All mesures are out of order (but I don't really care about that).

So I'm pretty happy to be able to pilot the plug even in degraded situation...

Still not able to deal with the curtain switch as I don't knoàw how to handle the " 'dps': {'1': '3'} " through the pluggin ( if it works) or if some modifications are needed...

Any further idea on all this epic tuya story? :)

I finally handled the switch to work :)

But still the pluggin does not handle well status (the domoticz switch is stuck on OFF state)...

Anyway, it works with a dummy that activate the switch created by the pluggin. Fair enough to be functionnal :)

Hello to all and thanks again tixi for the plugin

I could setup the plggin with the guide to catch device id and key

I've got some error in the log and when i run get_dps.py the message "A problem occur please retry..."

In the plugin setting I changes the value of debug to 1 and can read this :
2019-09-20 16:40:24.186 Error: (Tuya) 'onMessage' failed 'KeyError'.
2019-09-20 16:40:24.186 Error: (Tuya) ----> Line 534 in '/home/pi/domoticz/plugins/Domoticz-Tuya-SmartPlug-Plugin/plugin.py', function onMessage

Is it an issue with python, script ?

Thanks for your help

@xavierlp

Which kind of device did you use ? Action One ?

I get a Smart-Plug and a Led Strip from Action and they use v3.3 tuya version (MCUFW 1.1.5 for the Plug and 1.1.6 for the Led Strip)


@merlot
Did you think that it can e possible to choose which version to use on the plugin ? (3.1, 3.2, 3.3)
Can you be more explicit about how to choose version 3.3 using Pytuya 7.0.4 ?

Hello @deennoo

I am using OxaOxe
https://www.amazon.fr/gp/product/B07G2J ... le_o02_s00

I could red your post on github. For my side I don't know how to check the version of tuya.

thanks

Adding Set_Version(3.3) to the get_dps, turnOn and turnOFF scripts made it work*

*) Also had to modify the device generator to contain the key, and add a 3rd argument (key) to get_dps...

My get_dps.py is now:

It's hard to say without having the actual code as you're running it in your environment, but 'KeyError' often refers to missing dictionary items. For instance, the Parameters dictionary only has 6 entries (Mode1 - Mode6), trying to use Mode7 will not work, because it doesn't exist and referring to it (ie Parameters["Mode7"]) would generate a key error.
You'd have to go in to plugin.py and look at line 534 to see what is happening there...

Hello FearNaBoine

The line 534 is
_plugin.onMessage(Connection, Data)
from the
def onMessage(Connection, Data):
global _plugin
_plugin.onMessage(Connection, Data)

So nothning very clear.

so I read your previous message and I updated the get_dps.py

I've got now this message ValueError: Input strings must be a multiple of 16 in length

SO I removed the plugin from smartdevice app on my android and rerun the process but I have the same key and same error message.

Any ideas ?

thanks a lot

What about line 442?

When I run the script I do not get debug output, so I may be doing something wrong there, but I *do* get useful response data:"

Code: Select all

Plug State Information:
{'devId': '70116356840d8e5c3382', 'dps': {'1': False, '9': 0}}

Plug DPS List:

For debugging I uncomment theses lines in __ini__.py

log = logging.getLogger(__name__)
logging.basicConfig() # TODO include function name/line numbers in log
log.setLevel(level=logging.DEBUG) # Debug hack!

I've made these changes and now I can get the plugin working.

Plug State Information:
{'devId': '60417563840d8e68fe98', 'dps': {'22': 626, '19': 1334, '23': 34433, '9': 0, '20': 2358, '18': 634, '1': True, '24': 19774, '21': 1, '25': 1045}}

Plug DPS List:
1

However, when I add the device to domoticz, the values ​​are 0 and neither does work the on / off function.
But it works the on / off by command line (turnON.py, turnOFF.py).

What could be wrong?

Not sure whether that is the 'data format error' referenced in your output...
What is strange for my side is that key and device id are the same !!!!

It's not key and devID, it's devID and gwID... They key is different, but not shown in the debug info...
