Temp Alarm with negativ Temperatur

[andy]

Hi I just started with HG and it's really awesome.
I was looking around for a Temp. alarm, where I can trigger negative values.
I checked with the normal thermostat, but the range is from 5 -35 C.

I would like to monitor a freezer and alarm (by mail and GPIO OUT) when the temp. is higher as -15C.
So it could be an alarm module, where the threshold value and and alarm triggers can be configured.
Is there already something like that available ?

regards
Andy

I haven't looked at the thermostat code, but I'm sure that's simply a value that the author decided was a desirable range.  You have 2 easy options.

1) Modify the thermostat code to change the range you want
2) Duplicate the existing TC code (or just the section you need) and make the changes to the new program.

I'd recommend using option 2 as sometimes updates will replace built-in scripts and your customization will be lost.  If you make a new script based on the original, it won't get overwritten.

Hi bkenobi

Thanks fpr your reply.
This was also my first thought, I have copied the TC program, but couldn't find the part with the value.

I just found the values now in the widget. I think I need to create a new widget for me requirements as well.
