[REQUEST] Plugin for Tuya

I'm trying to configure a teckin sp22 plug but I get this message:

I've got some more configured(not this model) and not had had any problems

Any suggest ?

[pipiche]

My understanding is that the tuya devices ( sensors ) or zigbee compliant and have been tested on Zigate.

[tete]

No, these are not zigbee.
It seems as the output was different from what it expected.

Indeed , you are right plug and bulb are not zigbee

And some more time later ...

I've solved the mistery.

I was working with pytuya 7.0.3, but now I've seen that there is a 7.0.4 that includes support for 3.3 protocol while the previous one was just for 3.1.

Now, using that pytuya and adding a device.set_version(3.3) in the get_dps.py just before the device.status call it seems to work fine

{'devId': 'xxxxxxxxxxxxxxxxxx', 'dps': {'2': False, '25': 1300, '21': 1, '10': 0, '20': 2327, '24': 16000, '23': 28250, '1': False, '9': 0, '19': 0, '22': 602, '18': 0}}

Plug DPS List:
2;1

Now I have modified my copy of tixi_sincze plugin to set the protocol of my devices to 3.3.

Now I'll try the plugin, but the right solution would be to include this option as a parameter in Domoticz.

Simw time later ...

I have returned the previous smart plug and I've bought a new one, a double one for 16A.

And I'm having the same problems

So, let's start form the begining.

Is a packet like the one below correct to get the devId and localkey?

Is this a packet that belongs to a tuya device that can be used by this plugin?

Thank you very much indeed

We could look into that integration indeed with a dropdown box 3.1 / 3.3 for now ?

Will you do? Or are you asking me to do it? I can try, but I'm a newbie in git and I'm not sure how to contribute.

Anyway, after solving this issue, now, with the tixi_sincze plugin, after adding a dual plug, I get this error

And in devices, this is what I get

have I configured something wrong in the parameters?

I answer myself. The problem for a dual socket plug is in this code

Spoiler: show

for val in self.__unit2dps_id_list:

if(val <= max_dps): #single socket dps
Domoticz.Device(Name="Tuya SmartPlug (Switch)", Unit=val, TypeName="Switch").Create()
Domoticz.Log("Tuya SmartPlug Device (Switch) #" + str(val) +" created.")
Domoticz.Device(Name="Tuya SmartPlug (A)" , Unit=val+1, TypeName="Current (Single)").Create()
Domoticz.Log("Tuya SmartPlug Device (A) #" + str(val+1) +" created.")
Domoticz.Device(Name="Tuya SmartPlug (kWh)", Unit=val+2, TypeName="kWh").Create()
Domoticz.Log("Tuya SmartPlug Device kWh #" + str(val+2) +" created.")
Domoticz.Device(Name="Tuya SmartPlug (V)", Unit=val+3, TypeName="Voltage").Create()
Domoticz.Log("Tuya SmartPlug Device (V) #" + str(val+3) +" created.")
Domoticz.Device(Name="Tuya SmartPlug (W)", Unit=val+4, TypeName="Usage").Create()
Domoticz.Log("Tuya SmartPlug Device (W) #" + str(val+4) +" created.")

If in the dps_ide_list I have 1 and 2, as it's my case, in the first loop it tries to create Unit 1 to 5, and in the second one 2 to 6.

It should be something like this

for val in self.__unit2dps_id_list:

if(val <= max_dps): #single socket dps
Domoticz.Device(Name="Tuya SmartPlug (Switch)", Unit=val, TypeName="Switch").Create()

if(val == max_dps):
Domoticz.Device(Name="Tuya SmartPlug (A)" , Unit=val+1, TypeName="Current (Single)").Create()
Domoticz.Log("Tuya SmartPlug Device (A) #" + str(val+1) +" created.")
Domoticz.Device(Name="Tuya SmartPlug (kWh)", Unit=val+2, TypeName="kWh").Create()
Domoticz.Log("Tuya SmartPlug Device kWh #" + str(val+2) +" created.")
Domoticz.Device(Name="Tuya SmartPlug (V)", Unit=val+3, TypeName="Voltage").Create()

Domoticz.Device(Name="Tuya SmartPlug (W)", Unit=val+4, TypeName="Usage").Create()
Domoticz.Log("Tuya SmartPlug Device (W) #" + str(val+4) +" created.")

I think that the else statment for the group should also be corrected, but I'm setting to None, so I don't mind

Thank you

Hi merlot,
I don't know what version I am using. How can I find out the version? How can I update it?

[merlot]

Hi merlot,
I don't know what version I am using. How can I find out the version? How can I update it?

sudo pip3 show pytuya

Unfortunately, I couldnn't upgrade using the --upgrade option in pip3 and I had to copy/paste the __init from the project git site.

Anyway, I think the plugin is not working for 3.3 (I get no data in the devices) and I think that it's because the plugin is not using the pytuya methods to get the status

Yesterday, before introducing the version param, I tried to get it working by replicating the pytuya code for 3.3 protocol to extract_status, but without success.

I don't know the reason why the plugin was developed using connection and onMessage strategy, but I'll try a different approach: just using the self.__device.send_receive method when sending a command, in the onCommand cal, and self.__device.status() to get the status on each hearbeat. In the get_dps.py it works this status() method, so I hope it also does in the plugin, and it seems to me a cleaner solution, or at least simpler.

I'll keep you informed

Thank you

Got it



The only problem is that I get this error after switching on or off the plug. But it is turned on or off

I'll keep investigating, but any suggestion is welcome

My modified plugin works fine, with the mentioned errors, for multisocket plug



Some weird problems

You can see that V*A != W. But I have observed that I get the same values in Smart Life app. It's like the W is calculated for 110V not the real one. So, perhaps I'll modify to set the W as a calculation, not from the corresponding DPS.

If I plug something it takes much time (5 or more minutes) to get the right information. I haven't tried with the Smart Life app, but the get_dps.py gets the same zero values for A and W DPS

Comments are welcome

Got it



The only problem is that I get this error after switching on or off the plug. But it is turned on or off

Bon dia Merlot,
I have tested your code and I receive the same error as before.
I am doing something wrong ?
