WoSensorTHO (Model W3400010) - I get wrong measures

[lorenzopiazzi]

Current Situation

I'm trying retrieving temperature and humidity measures from the Sonoff WoSensorTHO (Model W3400010) using the parameters posted here: https://github.com/OpenWonderLabs/SwitchBotAPI-BLE/blob/latest/devicetypes/meter.md#outdoor-temperaturehumidity-sensor I'm using ESPHome and a ESP32 board. Unfortunately I get wrong values compared to the ones I can read from Switchbot official app in my smartphone. I think it might be because was not able to distinguish advertisments by data type. May you help me? thanks in advance!!
