ESP32 C3 compatibility #3

Hi,

Thanks for this nice project!

i've installed a Wemos C3 Mini on top of the pcb. This compiles and seems to work somewhat with the config below. I can connect it to home assistant, but i don't see any values, only ' unknown'.

D1 dsmr alias d5 = gpio 14 >> gpio1 on C3 D1 uart alias d7 = gpio 13 >> gpio4 on C3

Everything loks good, but no data :). Is there something obvious i might be missing? Or is there a way to validate esphome receives the data correctly from the P1 port?
