tinytuya Can't connect to device AllPetSolutions Pet Feeder F1-C/TA (T21)

Hi,

I am trying to setup my device to use with Home Assistant but was having issues so decided to try tinytuya.

I am also having issues with this for this particular device (Other devices work fine in both).

I have enabled DP instruction and can now control the feeder with all function on Tuya IOT Platform.

However when I try to even get device information with TinyTuya via the wizard I get:

[PetFeeder ] Error: No IP found

I have also noticed that when viewing the device via Tuya it has a different Device_ID compared to when accessing locally via TinyTuya scan where it seems to be broadcasting the UUID as the Device_ID instead.

Output from Scan:

Unknown v3.3 Device Product ID = e800gjvtrn6kjpuv [Valid Broadcast]: Address = 192.168.1.25 Device ID = d**********b9928 (len:16) Local Key = Version = 3.3 Type = default, MAC = No Stats for 192.168.1.25: DEVICE KEY required to poll for status

Output from Wizard:

{ "name": "PetFeeder", "id": "b**********daa27a8fcs7", "key": "**********34eb98", "mac": "::::51:5e", "category": "sp", "product_name": "PetFeeder", "product_id": "e800gjvtrn6kjpuv", "biz_type": 0, "model": "T21", "sub": false, "icon": "https://images.tuyaeu.com/smart/icon/ay1539074879262GYXmu/3c2ac7d0730f7dba50c478f3850c09a0.jpg", "uuid": "d ********** b9928" },

Do you have any idea what I can do next to try and debug further?

Many Thanks for any help you can give.

Here is a link to the device in question.

Hmmm, that's interesting. What happens if you edit devices.json with a text editor and replace the "id" value with the uuid and re-run the scanner?

Mar 05 '23 15:03 uzlonewolf

You can also try a short python script:

import tinytuya

d = tinytuya.OutletDevice(
      dev_id="********** b9928",
      address="192.168.1.25",
      local_key="**********34eb98",
      version=3.3)

print(d)

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

Hi Thanks for your message.

I had tried editing that before posting but if it is any use here is the output of the scan:

PetFeeder Product ID = e800gjvtrn6kjpuv [Valid Broadcast]: Address = 192.168.1.25 Device ID = ********** b9928 (len:16) Local Key = **********34eb98 Version = 3.3 Type = default, MAC = 44:01:bb:71:51:5e Polling 192.168.1.25 Failed: No response

Cheers

You can also try a short python script:

import tinytuya

d = tinytuya.OutletDevice(
      dev_id="********** b9928",
      address="192.168.1.25",
      local_key="**********34eb98",
      version=3.3)

print(d)

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

Hi,

Just tried your script and the response was just:

 > Fetch Status < 
None

Thanks

Can you turn on debug mode?

import tinytuya

tinytuya.set_debug(True)

d = tinytuya.OutletDevice(
      dev_id="********** b9928",
      address="192.168.1.25",
      local_key="**********34eb98",
      version=3.3)

print(d)

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

Try with uuid and id values if you can.

This reminds me a lot of #190. If they're similar devices then this should work:

import tinytuya

tinytuya.set_debug(True)

d = tinytuya.OutletDevice(
      dev_id="********** b9928",
      address="192.168.1.25",
      local_key="**********34eb98",
      dev_type = "device22",
      version=3.3)

d.add_dps_to_request(101)

data = d.status()
print('Device status: %r' % data)

Mar 05 '23 16:03 uzlonewolf

import tinytuya

tinytuya.set_debug(True)

d = tinytuya.OutletDevice(
      dev_id="********** b9928",
      address="192.168.1.25",
      local_key="**********34eb98",
      version=3.3)

print(d)

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

That looks more promising!!?

Thank you both again

That looks more promising!!?

Yep, that's it. So, to summarize the quirks of this device:

In broadcasts packets it sends the UUID instead of the Device ID, but when talking to it you must use the Device ID.
Status requests need a d.add_dps_to_request(N) or d.set_dpsUsed(...) with a valid DP set before the request or they will not return anything.
You can only retrieve the current device state one DP at a time (you will need to call d.set_dpsUsed(...) and then d.status() for every DP).

This is going to be a fun one to implement...

Mar 05 '23 17:03 uzlonewolf

Thanks making some progress :)

I Just ran the following script:

import tinytuya

d = tinytuya.OutletDevice(
      dev_id="***,
      address="192.168.1.25",
      local_key="***",
      dev_type = "device22",
      version=3.3)
d.add_dps_to_request(209)

print(" > Send Request for Status < ")
payload = d.generate_payload(tinytuya.DP_QUERY)
d.send(payload)

print(" > Begin Monitor Loop <")
while(True):
    # See if any data is available
    data = d.receive()
    print('Received Payload: %r' % data)

    # Send keyalive heartbeat
    print(" > Send Heartbeat Ping < ")
    payload = d.generate_payload(tinytuya.HEART_BEAT)
    d.send(payload)

    # NOTE If you are not seeing updates, you can force them - uncomment:
    # print(" > Send Request for Status < ")
    # payload = d.generate_payload(tinytuya.DP_QUERY)
    # d.send(payload)

    # NOTE Some smart plugs require an UPDATEDPS command to update power data
    # print(" > Send DPS Update Request < ")
    # payload = d.generate_payload(tinytuya.UPDATEDPS)
    # d.send(payload)

And interestingly after sending a command via Tuya app for manual feed I got this response:

 > Send Heartbeat Ping < 
Received Payload: {'dps': {'210': 1}, 't': 1678036668}
 > Send Heartbeat Ping < 
Received Payload: {'dps': {'206': 18945}, 't': 1678036668}

I am surprised it picked them up as I only specified 209?

Mar 05 '23 17:03 hijamie32

Yes, it will pick up async updates if you listen for them, you don't need to specify the DPs in that case. If you want to do this then I recommend setting persist=True after the version=3.3 so you don't miss any, otherwise it will close and reopen the connection after every update.
