Gradually turn on lights.

Rebooting the host Linux box doesn't help either. I am baffled as to why they do not evaluate.

[toggledbits]

What about where the values are used? Ignore the global expression displayed state/value for a moment, and look at any rules/conditions that use these globals. What do they show?

[cw-kid]

@toggledbits said in Is this possible? Store data from Asus Router ajax .asp page for Temperature data.:

What about where the values are used?

I didn't get that far yet in setting up the rule, as it seemed to not be working etc.

I was going to create other actions to send the values to a mutl-string device in Vera.

This is all that is in the rule currently

[toggledbits]

OK, but the target variable shown there is different from the one used in the expressions... RouterMemoryResponse vs RouterMemoryRaw

[cw-kid]

@toggledbits

That's because I just renamed the global expression to see if that made any difference.

[cw-kid]

Also how would you use a "Global Expression" value in a rules action, that works for local expressions.

[toggledbits]

Sorry, but let's stick with one issue at a time, please.

I want to see if that Expressions page view is actually broken and not showing complete/valid data. Make a dummy rule that contains a variable expression condition using the free memory value, and show what that displays for "current value" in both the rule editor and in the rule status view.

[cw-kid]

It says null

[toggledbits]

Can you make sure RouterMemoryResponse is defined before the other two variables in the list, restart MSR and check again.

[cw-kid]

I can yes, however before I deleted them all and recreated them, the "RouterMemoryRaw" was above the other two in the list.

[cw-kid]

OK done - I also restarted MSR and did a hard refresh.

[toggledbits]

And the rule?

[cw-kid]

It still says "null"

[toggledbits]

OK. In RouterMemoryFree expression remove all of the (\\d+) strings so that the middle/second argument to match() is just "Mem:" by itself (no spaces or other data). Restart and hard refresh. Then re-check.

[cw-kid]

Like this ?

match( RouterMemoryResponse, "Mem:")

[toggledbits]

Yes, that's fine.

[cw-kid]

It now says -

Last value: (string) "Mem:"

And the test rule trigger -

[toggledbits]

OK. So your pattern isn't matching, it seems is actually the problem. You may have some special characters or strange spacing in your pattern that I cannot see in the screen shots. There could also be a tab or other non-space character that looks like a space coming back in the shell command output.

Try using this expression for RouterMemoryFree:

match( RouterMemoryResponse, "Mem: (\\d+) (\\d+) (\\d+)", 3 )

[cw-kid]

It appeared to evaluate as it flashed green, Value is null however.

This is what is in the "RouterMemoryResponse"

Last value: (string) " total used free shared buffers cached\nMem: 426020 330068 95952 3488 0 37716\n-/+ buffers/cache: 292352 133668\nSwap: 0 0 0\n"

[toggledbits]

OK. Try changing all of the spaces to \\s* like this:

match( RouterMemoryResponse, "Mem:\\s*(\\d+)\\s*(\\d+)\\s*(\\d+)", 3 )
