WL-134 Pet Tag Sensor with ESP32 WROOM 32D

ESPHome

Hello,
I’m trying to set up this sensor with ESPHOME for HOME ASSISTANT and an ESP32 WROOM 32D.

So far I’m unable to get any readings from the sensor, even if it appears properly in the Home Assistant Dashboard.

Anyone have already used this sensor and could give me some advice?

This is my current setup:

uart:
  tx_pin: GPIO1
  rx_pin: GPIO3
  baud_rate: 9600
text_sensor:
  - platform: wl_134
    name: Transponder Code

I don’t know your sensor, but to start with:
tx_pin: GPIO17
rx_pin: GPIO16

also, you need to use 3.3V TX pin
