Thanksgiving lighting took a holiday

OK its working now in the terminal at least, I generated the key again with no password and now the above command works and does not prompt me for a password and the routers CPU temp value is returned.

I will try it in an MSR rule next.

[cw-kid]

Must be doing something wrong I am getting null in the local expression

Looks like the path is wrong it should be root not my home dir

Doesn't work either if I put in root instead of ~

I then tried copying the id_rsa file into my home directory and the .ssh folder in there. But it still doesn't work. So I am stuck now.

[toggledbits]

OK. The ~ means the home directory of the login user, and where MSR is running, that appears to be /home/stuart, so that's why the first attempt doesn't work.

The second attempt doesn't work because you used root/... instead of /root/...... it's a path, not a username, so it needs to begin with a /. Just changing that is unlikely to work, either, because regular users (like stuart) do not have (and should never have) access to the .ssh directory of any other user, especially that of root.

You need to copy the public and private key files to somewhere where Reactor has access, and specify the full path to that directory in the command line's -i option.

Alternately, use the public key for user stuart as the trusted key on the router, and let that user make the connection. This is by far preferable, as copying root's private key around to other places and giving it lower access permissions presents serious security risks.

OK thanks, I changed the command in the rule to this now:

ssh -i /root/.ssh/id_rsa admin@192.168.0.1 'cat /sys/class/thermal/thermal_zone0/temp'

I am no longer getting any alert errors in MSR but the local expression is not being populated. As your edit just said that is likely why.

I then tried this command instead.

ssh -i home/stuart/.ssh/id_rsa admin@192.168.0.1 'cat /sys/class/thermal/thermal_zone0/temp'

and

ssh -i /home/stuart/.ssh/id_rsa admin@192.168.0.1 'cat /sys/class/thermal/thermal_zone0/temp'

But I get alert errors again.

"Alternately, use the public key for user stuart as the trusted key on the router, and let that user make the connection."

That might be the best option. I need to work out how to ssh-keygen for a particular user though ?

Why? Just use the existing key in ~stuart/.ssh. If there isn't one, you just run ssh-keygen as user stuart rather than as root (no sudo either).

[cw-kid]

Got it I just connected to the MSR host logging in as me rather than root user and ran the keygen again, it created the two key files in my own .ssh folder now. I will add that to the router and try again. Thanks

[cw-kid]

Its working now with my own public key added to the router. The local expression now has data. Not sure what the \n is on the end though? It didn't do that in the terminal command line.

[toggledbits]

@cw-kid the \n at the end is a newline character. Linux is quite literal. You can push that string through the expression int() function and it will convert it to a number and ignore the newline.

No idea what that means, but I will search. I also need to do some thing with that data like round it, as it says"66986" which should read as 66.99 degrees

[cw-kid]

OK I see what you mean my local expression is a string. But how to change it to int ?

When you create a local expression it gives you no option of the type it should be.

[cw-kid]

Round doesn't seem to work as the raw data does not have a decimal point in it in the first place.

How to add a decimal point then?

[toggledbits]

int(RouterCPUTemp) / 1000

[cw-kid]

Perfect thank you !

I might even create a virtual device (multi-string plugin) on Vera and have MSR send these values to that also, so I can also have a tile in our Home Remote dashboard app showing this data.

[toggledbits]

You can wrap that in a round() if you only want one decimal (for example)...

round( int( RouterCPUTemp ) / 1000, 1 )

Even better, you have made my day! Thank you.

I have been worrying about my router getting too hot, now I will know if it does.

This post is deleted!

[cw-kid]

Well that works ! Quickly added a custom tile in Home Remote dashboard

And this is the Multi-String device in Vera.

Think I can pull other temps off the router also, like the WIFI chips.

[cw-kid]

Maybe I should also add a timeout to the ssh commands ?

ssh -o ConnectTimeout=10 -i ~/.ssh/id_rsa admin@192.168.0.1 'cat /sys/class/thermal/thermal_zone0/temp'

[cw-kid]

Think I just found a bug? try naming a local expression as "2.4GTempRaw" without the quotes in a rule and see what happens. I am stuck and cannot delete the expression or exist the rule. Had to refresh the browser to recover. Should of known not to put a dot in the name LOL.

I might have just corrupted the rule now I cannot add an expression named "24GTempRaw"

Or maybe its the numbers it doesn't like.

OK that's better.

[cw-kid]

You can do Wifi chip temps as well! Wonder what other commands I can send to get data back..
