Cumulus Support

Hello,

Raspberry Pi 4b
Cumulus 4.3.3 (build 4070)
Data Source: Ecowitt-Cloud

The following problem:
I would like to set up an email alarm that sends me an email if the CPU temperature is above 50 degrees Celsius.
I have entered the following in “User Alarm Settings”:
Enabled: yes
Alarm name: CPU temperature
Web tag: <#CPUTemp rc=y>
Type: Above
Value: 50
Email: yes
Email message: CPU-Temp. above 50°C. CPU-Temp is {0}°C.
Latch: no

Unfortunately this does not work. The error message is displayed:
2025-01-30 12:46:10 - User Alarm (CPU temperature): Error parsing web tag value: <#CPUTemp rc=y>
What am I doing wrong?

I do not think #CPUTemp has any parameters it just returns xxx.x and cannot be formatted.

Indeed it does. I missed that one, I'll get it fixed for the next release.

Interesting. I have a custom log with <#CPUtemp rc=y> and I never noticed but I did wonder why the chart was so jumping around integers iso a smooth curve

Looks like you "fixed it" Hans?

Your page shows the rc=y has not effect...

The original poster: the error message is slightly misleading in the is case. The error is not in parsing the web tag to a value (the rc=y will be ignored), but in parsing the output as floating-point number which is expecting a dot decimal.

Code: Select all

<#CPUTemp rc=y>	33,1 °C

Haha... I did not fix anything. It is a difference in parsing my realtimecustomlog file (an analogue to the CMX realtime file) where javascript splits the line on spaces, while when parsing the datafile of the customlog the C# code for creating the json, splits the logfile data line on the comma.

[EDIT:] Removed nonsense lines

@Mark: but actually, thinking it over, why can't the rc=y not be a property of the numbers systemwide (i.e. a setting to use the culture setting) After all, it is an output qualifier so it has nothing to do with the data acquisition and/or storage of the data. Or am I overlooking something now?

That would affect everything though, including the dashboard and web site data. How many people would want to do that?

Yes, I think I did not think it through to the end. It is confusing. Sorry for the remark.

Hello,

Thank you for your quick answers.

It would be nice if this could be changed in the next Cumulus update.
So that sending an error message when a certain CPU temperature is exceeded works.

I have another question regarding the “User Alarm Settings”. I can't find a solution.
I'll open another post for that.
