Cannot set DPS on zeegbe child devices but can read them

[balocon]

I have some TRVs (boiler valves) connected to a zeegbe gateway. I also have some other tuya smart devices but my problem is about child devices when I try to send them a command.

I have a dict with info of all devices (dev_id, cid, local_key, address, ... )

To conect with them I use this:

d = tinytuya.OutletDevice(dev_id=devMetaData['dev_id'],
address=devMetaData['address'],
local_key=devMetaData['local_key'],
dev_type=devMetaData['dev_type'],
version=devMetaData['version'],
persist=devMetaData['persist'],
cid=devMetaData['cid'],
parent=_parent
)
_parent contains a parent OutletDevice Object if device is a child, or just None Object if device it is a parent level device.

.. and then I can read all type of devices, parent and also child using for example this:

d.status()
or
d.status()['dps'][str(_dps)]

But if I try to use this to change state of a valve:

d.set_value(str(_dps),_value,nwait)

only works with parent devices. When I send it to a child devices (using parameter parent=), it say this:

Child devices has not IP address. I send the info to child (reporting its parent), but it seems like parent want respond but not translate the question correctly.

I am quite sure it is my fault, but need some help please.

Hi @balocon , sorry for the late reply.

Can you post a debug output of a successful child d.status()? What is the child device dev_type set to?

Although that response looks like it's from a v3.3 device, I'm wondering if it needs a v3.4 payload...

[balocon]

Thanks uzlonewolf for your answer.

I use 'default' for all my devices. All my valves are 3.4 but their hub, is 3.3, could this be a problem?

Here some log lines after a status() request valve:

I recently try send it command using lines below, but does not works. Always return 'None'.

.....
payload = d.generate_payload(tinytuya.CONTROL, {str(_dps): _value})
result = d.parent._send_receive(payload, 28, True, True, from_child=d)
d.close()

The child devices should be using the version of the parent (3.3) since it is the parent which relays the command. The Device(...) constructor actually ignores the passed version= and automatically sets it to the same version as the parent. What happens if you set all the valves to version 3.3?

[balocon]

You are right. Now it works perfectly, reading and sending command. Thanks a lot.
Just one comment. It is a little confuse, because valves are 3.4 like Tuya Developer Site say and, you can use 3.4 for reading, but not for send command. Fortunately, when use 3.3 for valves, it works for reading also.
Let me show you how I construct "d" object, maybe I do something wrong or not so correctly.

'devMetaData' var, save the values for each Tuya device, collect from Tuya Developer Web Site and other info like room, programing, etc

def get_device_conn(_id):

devMetaData = getDeviceMetaBySome(_id)

if devMetaData:


    if devMetaData['parent_name']:

        _parent_devMetaData = getDeviceMetaBySome(devMetaData['parent_name'])


        if _parent_devMetaData:


            c = tinytuya.OutletDevice(dev_id=_parent_devMetaData['dev_id'],

                            dev_type=_parent_devMetaData['dev_type'],
