scale.set_zero() about hx711

are you looking for the scale.tare() function? this will "reset" the scale to 0 (the function is present on all kitchen scales, so you know what i mean).

sorry, I just found your answer marked as spam email.
No, scale.tare() is nice. I'm looking fore a a function that reads the internal tare set weight similar to the set_scale() function. set_scale sets the max known weight. Something like set_zero() could only read the internal zero weight point which is calculated with scale.tare. Probably is already there but I don't see it.

I'm only asking for a possiblilty turn off the scale and on again with no new scale.tare(). Turning on again should read the "old" tare weight for the situation that the "old" weight is still on the weight.

i'm not sure i understand what you mean. you could use read_average() instead, without using tare(), store the returned value and pass it to set_offset() whenever you need to. set_scale doesn't set the maximum known weight.

ok, you got me right. I can use set_offset() to get what I want. I've tried it and it works. Great thanks for your answer.
