HX711 / I2C

[ljoncz]

Hi,

is there a way to use Gravity I2C 1Kg Weight Sensor Kit - HX711 with EspEasy?
https://www.dfrobot.com/product-2289.html

EspEasy detects the i2c device, but the list of supported devices is empty.
I'm using ESP_Easy_mega_20240414_collection_A_ESP8266_4M1M_VCC binary.

Thanks

We have working support for HX711 using the 'regular' interface board, but not this I2C implementation. And it's not a simple hack to support that, as the regular board has some quite specific handling to support both the A and B channel that's available. Not sure if that's even supported in that I2C board.

If you haven't yet ordered that unit, you'd better order one with the regular HX711 board instead. F.e. this one: https://www.dfrobot.com/product-1031.html
If you want this specific hardware setup, you can replace the I2C board with a regular HX711 board, as the loadcell is a generic device, as shown in the plugin documentation

The Collection builds do not include the list of devices supported to reduce the build size (and fit in more useful stuff/features).

Also you'd better use ESP32 (or some variant of the ESP32) for new projects instead of the ESP8266 as the latter one is really limited in RAM and storage space for the build.
