[SOLVED] Exec 2.0 and pipes

Add-ons Bindings

Hi,
I’m trying to find out how to use a pipe with the new exec binding. I want the output of this command:

sensors | grep 'CPU Temperature' | awk '{print $3}' | sed -e 's/\+//' | sed -e 's/°C//'

So I tried this:

Thing exec:command:Temperatura_CPU [ command="/bin/sh -c sensors | grep 'CPU Temperature' | awk '{print $3}' | sed -e 's/\+//' | sed -e 's/°C//'", interval=60, autorun=true ]

But I get this error:

2017-12-26 13:42:06.100 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model 'casa.things' has errors, therefore ignoring it: [53,46]: mismatched character '+' expecting set null
[53,124]: no viable alternative at input '<EOF>'

Then I tried this:

Thing exec:command:Temperatura_CPU [ command="/bin/sh -c sensors | grep 'CPU Temperature'", interval=60, autorun=true ]

But I’m getting the full output from sensors, ignoring the rest of the command.
If I escape the pipe:

Thing exec:command:Temperatura_CPU [ command="/bin/sh -c sensors \| grep 'CPU Temperature'", interval=60, autorun=true ]

I get this error:

2017-12-26 13:45:50.822 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model 'casa.things' has errors, therefore ignoring it: [53,69]: Number expected.
[53,46]: mismatched character '|' expecting set null
[53,74]: mismatched input ''CPU Temperature'' expecting ']'
[53,91]: mismatched character '<EOF>' expecting '"'

So, is there a way to use pipes with the new exec binding?
Thanks.

Put your entire command string onto a script, let’s say cputemp.sh.

For ur exec binding, just call that script.

You can also check out the systeminfo binding if ur interested with the CPU temp

Hi,
I didn’t know about the systeminfo binding, I’ll look into It.
The script was plan B, but I’d still like to know how pipes work.
Thanks!
