Sorry not related to this subject but I just can not get it working
Widget step h changes the value decimals 00.10 and I see small size numbers on the corner of the step h widget but the values does not change correctly on value widget or labeled value widget they both round up the values and show 37.000 not like I want it to show 37.10 or 37.1000
Correct… so I moved your issue to your own topic.
How have you setup the display widgets? The Labeled Value widget has more options for the precision ranges.
Can you show us the code you are using to transfer these values?
After you paste it here, please format it accordingly…

And I edited it for the the formatting as requested 
/pin.#/ - displays the value with 1 decimal digit (12.7)
/pin.##/ - displays the value with two decimal places (12.68)
I tried both of them still same
OK, I didn’t see exactly where your commands for the setp widget where, and didn’t feel like reading the whole thing… but logic dictates that if you want decimal precision, then you need your variables as Float… thus this should be what you use:
BLYNK_WRITE(V43) // Step widget set to 0.1 steps
{
float Stepvalue = param.asFloat(); // Get value as float
Blynk.virtualWrite(V44, Stepvalue); // Send to Labeled display with /pin.#/ setting
}
or 0.01 steps with /pin/ setting:
ok ı got it working but it shows for couple of seconds and goes back to 0.00
That will be something in your code then. What Vpins are used for the step and the display?
Thank you so much Gunner you saved my day
