MSR UI on a mobile browser

[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

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.

@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..

[cw-kid]

This is much more powerful than I imagined. Seems you can send any old linux command like "free" to see the memory usage. I haven't figured out how to extract and parse just a part of the returned data yet though, say just the "Used" memory value.

(string) " total used free shared buffers cached\nMem: 426020 303308 122712 3404 0 39212\n-/+ buffers/cache: 264096 161924\nSwap: 0 0 0\n"

"303308" is the used memory value, no idea how to extract just that part of the data to another local expression though as its not formatted like JSON data would be.

@cw-kid you're going to have to learn "regular expressions", which are patterns that can be matched in strings. It's another rabbit hole to go down, but here's a specific solution you might build on. Using your response string:

The match() function (refer to the docs) will match a pattern to a string. In this case, the pattern contains "regular expression groups", which are the parentheses and their contents. These groups contain \d+ patterns (you have to specify them as \\d+ as shown because of string escaping in the language)... the \d pattern matches a single digit 0-9, and the modifier + after it tells it to match one or more occurrences — so each \\d+ matches a number made of one or more consecutive digits. So this whole pattern basically finds the word Mem: in the string, then from there finds the six numbers that follow. The 3 in the last argument tells match() to return only the third matched item, which is the number 122712, the amount of free space (it's third in place in the string of numbers based on the header line above it).

You can Google around to find regular expression tutorials.

@toggledbits

Thanks I will take a look at the pattern matching.

I realised I need a Global Expression, for my second rule to trigger from. As I cannot use a local expression that is in one rule as a trigger in a different rule etc.
My second rule will be the one that triggers if the CPU Temp value is greater than 80 and it will notify me by repeated TTS announcements etc.

So I created two new Global Expressions.

The first rule I setup that gets the CPU Temp via the ssh command, now also sends that raw response value to the Global variable as well, that is named "RouterCPUTempRaw" that works fine OK.

However my second Global variable called "RouterCPUTemp" that changes it to "int" doesn't seem to evaluate.

When should it evaluate ?

If I restart MSR then it evaluates then and updates correctly.

Maybe? its because to test it and force the value to be 81 I sent in this URL to MSR.

Thanks

EDIT: I guess as a work around I could delete the "RouterCPUTemp" global variable and just have my second rule trigger if the value in "RouterCPUTempRaw" global variable is greater than 80000

EDIT2: I just did that and that seems to work OK instead.

[cw-kid]

I tried the pattern match in a new test rule, I think I did it correctly but I am just getting null in the expression for some reason.

I don't get any alerts or errors in the notifications area either.

[toggledbits]

Local expressions are only evaluated when the parent rule is evaluated. The changing of the rawResponse local variable does not cause an evaluation of the other variables. These would need to be global.
