LD-TX->MCU-RX

But all sensors displayed unknown

Please i need HELP

Hi - Have a read of the linked topic - also paying attention to formatting your YAML using preformatted text tags:

Edit your post using the correct tags and someone may be able to help.

Try TX-TX and RX-RX and it should work just fine.

Hello, This is Annie from Hi-Link. I consulted our technicist and got the solution as follows. You could try to power HLK-2410C alone and try RX-RX, TX-TX and Gnd-Gnd.

Hi,

I am having the same issue. Below is my YAML code

I have it working on an esp32dev board, but can’t get it working on nodemcu32-v-3

Any help would be appreciated - Thanks
