Tuya WiFi Smart Plug

To talk to the device, you need 3 things:

1. The device IP address
2. UUID / Device ID
3. localKey

You can get this by sniffing the traffic the Android app makes with a SSL Capture app. When adding a new plug, some of the requests should contain something about a 'localKey'. One of the requests should also return all devices as well as their corresponding localKey from their server.

It looks like the plug currently talks with

• mq.gw.tuyaus.com via MQTT
• a1.tuyaus.com via HTTP

The localKey seems to change every time the device is reconnected to the cloud.

The status output from the AWP04L smart plug looks like this. The plug has monitoring features and should return the voltage and amperage (hence the calculated wattage).

{u'devId': u'02200194dc4f22137d7f', u'dps': {
u'1': True,        outlet status
u'2': 0,           ??
u'5': 56,          watts (5.6)
u'4': 73,          amps (0.073 amps)
u'6': 1198         volts
}}

You will probably still need to allow it to connect to the cloud once. If you don't let it completely connect, some features like voltage/wattage are disabled from the output (?). MQTT must be working, or else these features are disabled:

{u'devId': u'02200194dc4f22135606', u'dps': {u'1': True, u'2': 0}}
>>> x.status()
{u'devId': u'02200194dc4f22135606', u'dps': {u'1': True, u'2': 0}}
>>> x.status()
{u'devId': u'02200194dc4f22135606', u'dps': {u'1': True, u'2': 0}}
>>> x.status()
{u'devId': u'02200194dc4f22135606', u'dps': {u'1': True, u'2': 0, u'5': 0, u'4': 0, u'6': 1184}}
>>> x.status()
{u'devId': u'02200194dc4f22135606', u'dps': {u'1': True, u'2': 0, u'5': 0, u'4': 0, u'6': 1184}}
>>> x.status()
{u'devId': u'02200194dc4f22135606', u'dps': {u'1': True, u'2': 0, u'5': 0, u'4': 0, u'6': 1184}}
