DS18B20 Sensors

[codedmind]

The module show temperatureC and TemperatureF, and i would like have some time of datetime stamp to know the last time the values are updated.

For instance if i disable the program (or for some reason stop working) the modules keep show the last values and we will not know if they are current values or not.

All right... there was missing code in the sensor widget. I added it.
To update copy the attacched sensor.json file to the /usr/local/bin/homegenie/html/pages/control/widgets/homegenie/generic/ folder.
Then refresh the browser page and the date should appear like the screenshot.

HG is crash after some time, and the the program reports errors...


"Line 0, Column 0 (Code to Run):
    Input string was not in the correct format"

[Gene]

Does it happen sometime when restarting the program or while it's running?
What do you mean that HG crash? Did you have to restart HG or just the program?

i must start HG because it stops... i try to understand what happen because everything has working... but then when i go try the new *.json file hg has stopped...

I start up and the the one wire program not run anymore, and report errors when i try update the script

[codedmind]

Do this have some type off cache? I remove the modules, i reset all hg and now i can't even run the first hgx you send me... all of them returns the same string error.

[codedmind]

My bad, after chage the script i save and click run and i think that is the problem.. i do back and only then hit save... the script editor reports errors, but it is working again... let see if hg crash or no

[codedmind]

  Gene, the crash still occur, i can't identify why, but after some time homegenie stop working and i must start it again... before onewire program this don't happen

Looks like it is some issue related to mono / IronPython. I'll try updating IronPython libraries but this will require some time since latest IronLanguages release it is only available as source code.
Also I'll get one of these DS18B20 so I can make a real test.
By the way the same program can be written using C# so HG it would not crash.
Do you know how to translate the script code from Python to C#?

Cheers,
g.

[codedmind]

Not really.. i would prefer python

However if you can point me to some examples where i can see how to do c# in hg i can try

[Gene]

I'm doing it.
Please test the attached C# script and let me know if the app reads temperature values correctly.
You have to change the sensorid from the code at line #41.
If this is working I'll complete the script to work as the python one.

Cheers,

when try save the changes i get this

Line -16, Column 0 (Code to Run):
    Metadata file `Microsoft.CSharp.dll' could not be found

[Gene]

Missing some dependency? How did you install HG?
I'm attacching the completed version of the program.
I guess you cannot update any C# program? Can you try creating just a new empty c# program and compile it?

g.

[codedmind]

i download and install the rpi version, before i run the apt command that is in the docs

[Gene]

Mmm... that's strange...
We can work around this though.
Copy the precompiled app file to /usr/local/bin/homegenie/programs/ folder.
But you must change the number in the filename to match your imported program ID number.
After that, you just enable or restart the app.

Cheers,
g.
