Popp Z-Rain sending values in incriments other than 0,5mm

[calania]

Hello! I have a Popp Z-Rain sensor that I have used for a number of years and has always worked perfectly. It has always sent value in increments of 0,5mm but after I recently reinstalled Domoticz and started from scratch some values are being sent as 0,4 or 0,6 mm instead of 0,5mm. I'm guessing this is some rounding error but I have newer had this issue before. Does anybody know why this might be happening?

I had/have the same problem, even to a point where I replaced my Popp Z-rain sensor for a new one.
After the replacement it went fine for a while, but again now I do sometimes have this problem.
So I don't think it is the Poop Z-rain itself but it has something to do with Domoticz, perhaps some kind of rounding off numbers in the Domoticz program code.


A other problem is that the line graphs are WRONG not representing the truth. Because the Popp zwave does not sent zero on days that it does not rain. It sends no data at all so the graph connects day one (say 5mm rain), with day 30 (say 7mm rain). Then it looks in the graph if it was raining the whole month while in fact it was only raining on day 1 and day 30.

Change presentation to a bar graph and it will represent the true rainfall, for sensors which send zero and no value's on days with no rain......
