HomeyDuino CO2 sensor

@Lars_Machiels, nice post and thanks for sharing !
Actually interested by this topic, I replied to a copy of your post by an usurper,
Funnily I was asking for more info, and every detail is available here in its original

It is so annoying, I’d like a moderator to check the issue, any idea on how to raise it to moderators ?
@Bram, here is the fraud below (raised it with the flag as spam)

Many thanks

Hi Lars,

Sorry to bump up this topic, but i could not find anything similar with the TTGO ESP32 print in combination with the Senseair S8. Do you still have the code ?

The S8 works with UART (serial). Any device with UART should work with the S8. For reading the CO2 level use:

byte readCO2 = {0xFE, 0X44, 0X00, 0X08, 0X02, 0X9F, 0X25};
