The label should fix the issue definitely... The chart is finally better - the domoticz only ignores the first record, so the number is -1 bucket.

I expect at least something like my ascii art chart :
honza@u2504:~/dev/domiticz-db-backups$ ./chart.sh rain day
Terminal size detected: 125x37 -> Chart size: 115x12

rain.1 (#43) samples=115 range=0.00..0.40 [2025-10-17 08:45:00 -> 2025-10-17 09:19:12]
0.40 ┤ *
0.36 ┤ *
0.33 ┤ *
0.29 ...

The cahrt shows 0.8 mm rain fall instead of 2 mm. Not a mysensors issue.

I propose on the rain chart solve the bug by bold huge res or orange warning on top :

DOMOTICZ DRAW THE RAIN CHART INCORRECTLY BUT BE PATIENT ONE DAY IT WILL DRAW BETTER.

Hi, rain guage issue details. It still fails but not in the mysensors. It is clear the domoticz is the root cause.
I attaching a clear picture of a chart and db list.

- Today hit the sensor twice according to the database.
- The chart does not show the events at all
- it is 9:00 now and the chart ...

The sensor processing (rain volme) seems works for now - still no rain. Sending incremental value solved my issue. I will update this thread asap.

Hello kimnot,

the float is fine.
I have incremental value - that is correct.

I think there is problem with db handling and chart processing.

I have 5 events in the db (now Oct 10, no rain last two days) :
#1 0.2mm - 2025-10-07 15:55:00 (+9 db records of the same value after 5min intervals)
#2 0 ...

Hello waltervl, thank you for the response.

Mysensors are more general framework than sensors standard. I am using the rain gauge as simple as possible - when the bucket is full I send a volume number as S_RAIN / V_RAIN. I do afraid there is issue with mysensors.

Hi because myscontroller is oneman show and full of bugs and egeoffrey dead I test domoticz.
Unfortunately this was short... did someone ever install this under ubuntu?
The install instructions are not up to date - https://wiki.domoticz.com/Linux .

assume ubuntu 25.04 on amd64.
