Nedis Power Plug WiFi Signal Strength

Hi. I'm using tinytuya. How can I get WiFi Signal Strength. Tuya Cloud API show that, but is it possible get this info locally too?

```json
{
  "result": {
    "eventTime": 1756837637844,
    "indicatorType": "RSSI",
    "signal": -69,
    "signalLevel": "良"
  },
  "success": true,
  "t": 1756837648501,
  "tid": "7b255722882a11f0805d96c8b66247b7"
}
