Cannot connect to local device

[wallforfry]

Hi !

I'm trying to connect my Avidsen Homefresh AC but it's never found by the scan command.
I know that it's a v3.3 Tuya API, I've got the right key and deviceId.

I tried to run a custom script calling the find_device function. This gave me some results but idk what to do know. Is this encrypted payload normal ?

I tried with a status() call too, but it always ends with socket unable to connect

Also :

• The device is correctly advertising its MAC (checked in my arp table)
• It's ping-able without any issue

Hi @wallforfry , I would try:

import tinytuya

# Turn on debug
tinytuya.set_debug(True)

# Connect to Device
d = tinytuya.OutletDevice(
    dev_id='DEVICE_ID_HERE',
    address='192.168.1.13',    
    local_key='LOCAL_KEY_HERE', 
    version=3.3)

# Get Status
data = d.status() 
print('set_status() result %r' % data)

Thank's for your fast answer, just tried and got :

Side note: when I used localtuya before, I had to put dp 1 in the reset field:

Setting the 'DPIDs to send in RESET command' is optional. It is used when a device doesn't respond to any Tuya commands after a power cycle, but can be connected to (zombie state). This scenario mostly occurs when the device is blocked from accessing the internet. The DPids will vary between devices, but typically "18,19,20" is used. If the wrong entries are added here, then the device may not come out of the zombie state. Typically only sensor DPIDs entered here.

But I think that your "default" dev_type already handle that

How do you know it's a v3.3 device? That error's looking like it's either a different version or there is already a connection to it open from another program. A lot of devices stop broadcasting discovery packets when a connection is made, which would also explain the "not found by scan" issue.

[wallforfry]

@uzlonewolf I previously connect it with localtuya which totally works with 3.3 version.

Then I reset the device to renew the localkey and stop all others connections (also closed the smartlife mobile app just after pairing). I'll try to do it again multiple times just in case 🤞
