HX711 and Home Assistant #229

Hi, Thanks for the great software. I have made a scale using load cells and a HX711 amplifier. No issues with programming the CC2652 module and the integration is also ok. Saved a custom converter, also ok. Th thing is the calibration. My sclae factor switch is not available in HA/Z2M. What am I doing wrong here? See images: afbeelding HA HX711

@epvdvalk Hi, I see the scale factor field in your Z2M. What is wrong, exactly?

epvdvalk commented 1 year ago

Hi ,thanks for the fast reply!

The switch for “enable zero calibration” is not available in Z2M.

Kindest regards, Epko.

It also says “no converter available for state” (undefined)

Hi, I finally got it working and calibrated the scale. I use the scale to measure the amount of salt in my water softener. Measured the salt weight and calibrated the scale. It started at 20 kg's but after a day it started drifting and after a week the scale shows -37kgs. How is this possible? Is there a fix for it? scale

This is the graph for the last week.

@epvdvalk Sorry, but I cannot repeat this problem in one-day test. Can something enable/disable the tare mode automatically?

epvdvalk commented 11 months ago

Hi, It is just not working as expected unfortunately. I have switched to a different type of load cell (the type you are using) but still there is no switch that enables the tare function unless I program a switch in the firmware.

Can I add multiple HX711 modules to 1 CC2652P module?
