These settings follow the sensor datasheets and the built-in drivers but haven’t been checked on this module with the current firmware yet.

Sensors	SGP30: TVOC and eCO2
Connection	GROVE I2C (0x58)

Template

First apply your board's template from its board page, so the I2C pins are set. Then paste this into the Board Template box on the node's Templates page, Preview and Apply. It sets only this add-on's settings and works on any chip. See Add-on templates.

Notes

• Plug it into the GROVE port. The Atom S3 Lite and NanoC6 board templates set GROVE as I2C bus 1. On another board, set I2C bus 1’s SDA and SCL pins on the Hardware page first.
• Applying the template needs firmware newer than v5.0.0b2 (ESPresense#2555). Older firmware asks for a "chip"; set the values on the Hardware page instead.
• Publishes tvoc (ppb) and co2 (ppm). The CO2 value is an estimate from the VOC reading, not a measurement, and it shares the co2 topic with an SCD4x.
• The SGP30 needs a few minutes after power-up before its readings settle.
