Looking at the Senseair page here: S8 LP | Senseair
On the variations tab, the model Senseair S8 LP matches the number on the sensor.
However when I look at the modbus documentation, it states the function code 0x04 for reading CO2 level.
When I look the AirGradient code, I see that function code 0x44 is being used.
I found that SenseAir LP 8 seems to have this 0x44 function code. (see modbus modbus documentation on the documents tab here: LP8 pin headers | Senseair)
But LP 8 model number does not match 004-0-0053
I am confused. What is the model of the AirGradient Kit SenseAir and what is the right modbus documentation?
