Can't get LD1125H working with ESPHome and D1 Mini

Has anyone gotten this to work? My config is below

@Hilink-Lucia Any advice?

Not sure what issue you are having, but I was not getting a response from the sensors in HA as they were all showing as ‘Unknown’. It seems I had to reverse the connections of the URX/UTX pins as opposed to what’s listed in the diagram linked below.
