This example requires you to avoid having weights on the scale when the sketch will start because here there is the scale.tare(). I need to use the scale in a different way: I can't remove the weight when the sketch starts. Basically, I need to retrieve the value, send it, and after that the Arduino will be switched off. Again, when the Arduino will be switched on, I'll need to take the weight value without removing what I have on the scale. Basically I need to avoid to tare the scale. How can I do this? Obviously, I tried removing the tare line code but this doesn't work.

Scale tarevs zero

I would assume that you aren't going to re-tare every 10 minutes. Maybe once per installation? Once per manual update-tare-button-push? And the every 10 minute power-on would normally be merely reading the tare from EEPROM?

ooh clear For some reason, I thought that you were suggesting using some kind of secret key-code that you enter - and that's it! scale is tared

I calibrated the weight scale, and I also tried the example: Load Cell Amplifier HX711 Breakout Hookup Guide - SparkFun Learn

Tareweight

Hi all, I created a weight scale using 4 load cells and one HX711. Basically I followed these tutorial: I calibrated the weight scale, and I also tried the example: Load Cell Amplifier HX711 Breakout Hookup Guide - SparkFun Learn

From your link, if you don't want to use EEPROM, you could use the calibration code, but also print out and record the offset value and use the production code.

I'll try this approach…but, regarding the EEPROM, I'm not an expert, but, if I'm not wrong, there is the limitation about the maximum number of writes (around 100k) ..assuming that I’ll do one write every 10 minutes... Is this a negible thing?

Digitalscale tare

Also, the the EEPROM.put() routine only writes if there is a difference, so if the tare data isn't actually changing it doesn't actually do the write.

You can't avoid taring at all. But you can to tare scale once, write the tare value to EEPROM and read it when the sketch starts
