Co2 sensor MH-Z19 would be great!

The ESP Easy plugin for MH-Z19 could be used as a basis. Unfortunately I have no clue how to write such module.... I can help debugging though.

Yep, mine arrived a few days ago. The protocol looks quite simple so I hope I can get it into 1.8.0

Is UART used anywhere else, I can't find anything searching around, but it seems like it would be easier to add soft UART https://github.com/plieningerweb/esp8266-software-uart and use then be able to just send and receive things to it.

Done :) it's in 1.8.0
