Slowly response

[EnricGarrigo]

Hi all.
After some tests with Tuya devices, we have observed that once we have a load connected and powered, the API returns '0' to current values at least during 20-30 seconds. After this period, the 'cur_current' data is received with the right value.

Because that, if the load is powered on for a period less than 20 seconds (for example, in little intervals of 10 seconds), we have an accumulated current consumption of '0'.

Is it possible to accelerate the response time? Is any way to obtain the current values immediatly?

Thanks!

Update: if we enter in SmartLife app to see the values, the API refresh immediately. Any refresh on app provoke an immediately refresh of the values read from the API.

Hi @EnricGarrigo - it sounds like your device needs to the UPDATEDPS command to cause it to update the power metrics:

import tinytuya
import time

d = tinytuya.OutletDevice(DEVICEID, DEVICEIP, DEVICEKEY)
d.set_version(3.1)

data = d.status()
print(data)

print(" > Wait 5 sec < ")
time.sleep(5)

print(" > Request Update < ")
result = d.updatedps()
# some require params that you wish updated
#result = d.updatedps(['18','19','20'])
print(result)

print(" > Fetch Status Again < ")
data2 = d.status()
print(data2)

print("")
print("Before %r" % data)
print("After  %r" % data2)

HI @EnricGarrigo - That code assumes you have the tinytuya.json file already set up via the wizard. If you don't, you will need to provide your credentials like this to run the authentication calls for you:

# Connect to Tuya Cloud
# c = tinytuya.Cloud()  # uses tinytuya.json 
c = tinytuya.Cloud(
        apiRegion="us", 
        apiKey="xxxxxxxxxxxxxxxxxxxx", 
        apiSecret="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", 
        apiDeviceID="xxxxxxxxxxxxxxxxxxID")

Hi.
Following your appropriate advice, I have changed my python code for use tha API calls. For now, this is my part of code that reads the device dps:

while True:
response = openapi.get("/v1.0/iot-03/devices/{}/status".format(DEVICE_ID))
print(response)
time.sleep(1)

When I run this code, the behaviour is the same that with tinytuya library: I'm getting a value of '0' for the 'cur_current' dps. If I switch on the radiator that is behind the smart switch, the value is still '0' during next 30 seconds. Only after this period, I receive a cur_current value of '8834', If I switch off the radiator, I receive a value of '0', five seconds after switch. If I switch on again, I receive a value of '8834' only 30 seconds after switch on.

With this behaviour, if I switch 'on' and 'off' the radiator every 10 seconds, I will obtain an accumulated value of '0' for the current, that is obviously not true.

Yes, that does not seem helpful. It sounds like this device needs a "updateDPS" command. It may be that this is not possible using the cloud, I don't know. However, this can be done locally on your LAN. I believe @uzlonewolf provided this suggestion which I would recommend as well:

Can the PC "see" the device, or is the device behind a firewall? As long as the PC can see the device you can still talk to it directly even if they're not on the same network.

import tinytuya
import time

d = tinytuya.OutletDevice(DEVICEID, DEVICEIP, DEVICEKEY)
d.set_version(3.1)
data = d.status()

print(" > Request Update < ")
result = d.updatedps()
# some require params that you wish updated
#result = d.updatedps(['18','19','20'])
print(result)

print(" > Fetch Status Again < ")
data2 = d.status()

print("")
print("Before %r" % data)
print("After update  %r" % data2)

I don't have any IP for the device:

How can I use the 'local' version of tinytuya in this case?

Thanks

Do you know the network address of the LAN that runs the devices? If it is 192.168.0.x, use something like this:

python3 -m tinytuya scan -force 192.168.0.0/24
