[ESPHome] WL-102 Transmitter 433mhz (Solved)

ESPHome
6

@Lainol you’re a legend!

So I ended up flashing the ESP32 with tasmota (using the web flasher) and configured the Rf Receiver on the right pin.

When I pressed the Off button on the remote it returned the following on the tasmota console:

06:26:51.928 MQT: tele/tasmota_FB1A7D/RESULT = {"Time":"2023-11-08T06:26:51","RfReceived":{"Data":"0x452203","Bits":24,"Protocol":1,"Pulse":393}}

I took "Data":"0x452203" and passed it through a hexadecimal to binary converter and the result was 010001010010001000001110 which was the same as the output from ESPHome – so I knew I was on to something. The only difference was Tasmota showed the “Pulse” value and ESPHome did not.

I was able to send the command with Tasmota (from the command line) with this command:
RfSend {"Data":"0x452203","Bits":24,"Protocol":1,"Pulse":393}

Make sure the transmitter pin is configured in Tasmota before trying to send the command.

So I followed the instructions from the post you linked [here] and added the pulse to ESPHome and flashed it to the device. To my surprise, it worked!
