Notes:
A Tuya IoT project must be created for this to work
Tuya device authorization can expire, which will result in errors in Home Assistant (Presumably) the Tuya app on the smart phone needs to be closed for this process to work reliably

Early 2023, adding/configuring Tuya devices in the Home Assistant LocalTuya community add-on is (still) a rather confusing process. Adding a device involves manually configuring the Data Points, which are the properties like relays and power consumption a Tuya device exposes through its local API.

These properties do not advertise themselves as a friendly name or data type, but as numbers. Finding what property these DPs represent is quite cumbersome, hence I created this repo to remind me of this process and also include the DPs for several of my Tuya devices to save future me from having to look them up (again).

2023-01-04: I found and included a table containing known 🔗DPs for Tuya v3.3 devices

1. Login to the Tuya IoT Platform
2. Select 'Cloud' > 'Development' from the menu
3. Select your project
4. Goto 'Devices'
5. Click Debug device in the Operations column
   💡 hidden if viewport is too narrow
6. Select 'Device Logs' tab
7. Open the browser Developer Tools (EDGE:F12) and open the Network tab
8. Select a DP from the 'Select DP ID' dropdown
9. Hit 'Search'

In the background a network request will be done, available as 'list' in the network calls overview.
Select that request and open the 'Payload' tab.

The payload will look similar to this:

{
  "startRowId": "",
  "pageNo": 1,
  "pageSize": 10,
  "code": "2",
  "startTime": 1672692811363,
  "endTime": 1672865611364,
  "projectCode": "*****",
  "sourceId": "*****",
  "sourceType": "4",
  "deviceId": "*****",
  "pageStartRow": "",
  "region": "EU"
}

The "code" value is your DP ID. In this case 2, which translates to the 'Switch 2' the relay for socket #2 of the Blitzwolf SHP7 smart socket.

Once the device has been selected, the flow will be like this:

Some clarification of DPs:
Add Electricity = Power consumption since last report
... coe = ... coefficient

Advertised as SWITCH2

BW-SHP2: Wifi Smart Socket 16A with power monitoring
Also sold as Gosund SP1 and Tecking SP22

BW-SHP5: Wifi Smart Socket 16A with power monitoring, has 2 USB ports that can be switched separate from the main socket.
Also sold as Gosund SP112

List of DPs for Tuya v3.3 devices.
Table contains the DPs that a device may expose. In general it is a useful lookup table to identify the DPs read by LocalTuya.
