Template

Section titled “Template”

First set up the I2C pins: apply your board's template from its board page(the Atom S3 Lite and NanoC6 templates make the GROVE port I2C bus 1), or set I2C bus 1's SDA and SCL pins on the node's Hardware page. 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

Section titled “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 v5.0.0b3 or newer (ESPresense#2555). Older firmware asks for a "chip"; set the values on the Hardware page instead.
  • Publishes ahtx0_temperature and ahtx0_humidity.
