Grove SHT31 / SHT40

Unverified

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	SHT31 or SHT40: temperature, humidity
Connection	GROVE I2C (0x44)

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.
• The SHT driver detects either chip on 0x44 or 0x45, so one template covers both versions.
• Publishes temperature and humidity, the same topics as an SCD4x CO2 sensor, so don’t run both on one node.
