thanks , after recovering I’ll try this

H102 · November 23, 2019, 7:26pm

Need to add leading / to var and remove the last / no sudo needed.

ls -al /var/lib/openhab2/cache

Just opened ssh to verify above command is correct.

Looks good.

Use openhabian-config tool and select option to delay starting rules (option 44) for optimal startup then restart OH with sudo systemctl restart openhab2 if restart is not correct then just use stop and then same command with start.

A_Moktar · November 23, 2019, 7:37pm

OK thanks

still getting the same errors

H102 · November 23, 2019, 8:30pm

See what happens if you change the var at the top of the rule from

var Timer BlinkingTimer = null

to

var Timer BlinkingTimer

A_Moktar · November 23, 2019, 8:37pm

the rule stopped because of the if(BlinkingTimer === null){ I guess

H102 · November 23, 2019, 8:46pm

Why all the timers and why the first if statement? It’s canceling a timer that hasn’t even started.

var Timer BlinkingTimer = null

rule "Network Router OFF"
when
    Item Router changed to OFF
then
    logInfo("network", "Router is offline")

    if(BlinkingTimer !== null){
        BlinkingTimer.cancel()
        BlinkingTimer = null

rossko57 · November 23, 2019, 9:20pm

It’s a precaution, and costs nothing to do. Failing to take account of unexpected rule entries account for a good many errors.

The second if() is indeed redundant; if the variable wasn’t null before, it is by now.

rossko57 · November 23, 2019, 9:23pm

What makes you think it stopped? Is there an error report we should see?

var Timer BlinkingTimer = null
is good practice cos us mere mortals can see what it does at a glance
var Timer BlinkingTimer
will do the exact same thing though.

Just in case, you do not have any Timer imports you may have seen suggested in old postings?

This is a bit alarming really -

2019-11-23 15:14:44.013 [INFO ] [lipse.smarthome.model.script.network] - Router is offline
2019-11-23 15:14:46.856 [INFO ] [lipse.smarthome.model.script.network] - LED is NULL, and will set ON

Nearly three seconds between those logInfo, when it should be a few mS. How stressed is this system? Are there many other timer jobs grabbing resource?
I note that there seems to be an MQTT broker initialising in the middle of all this, are we in the midst of a bootup?

Note this old post for same error -

You might expect an orphaned timer error after editing a rule file - but your timer should only take seconds to blow up.

A_Moktar · November 24, 2019, 8:51am

yes , we are in the midst of a bootup
I’m looking at the post you referred, thanks

thanks all for helping

A_Moktar · November 24, 2019, 9:36am

I’m so frustrated, here is my latest errors
I’m trying to check the internet connection and blink the led according to the problem in the connection, first I’ll check if the router is online, if not blink the led fast, if online go to check the internet connection if offline blink the led slowly, if online turn the led on, but as you see i’m still in the first step and errors stopped me

There is something weird about your BlinkingTimer variable; I don’t know what, duplicate declaration somewhere else? don’t know.

But it breaks your rule …
... Rule 'Network Router OFF': An error ... Cannot resolve proxy: network.rules#/1
I’m pretty convinced that comes from the cancel attempt
AND it breaks the timer block
... cannot invoke method ... .Timer.reschedule... on null
obviously from the reschedule attempt.

Have a think about that; the “OFF” rule breaks before it creates the timer, but the timer breaks as well?

You’ve hidden from us the logInfo output from the beginning of the rule, that would reveal multiple entries into the rule. So first, find out if your rule triggers multiple times.

You’ve taken the logInfos out of your timer code that would reveal what that is up to. You’ve made the flashing schedule more demanding. It’s not helping. I understand your frustration, we’re looking for an oddball race condition.

Do some basics -
Make sure you have no timer import in that file.
Make sure your global var Timer is at the top of the file, before any rules.
Sprinkle logInfos to see how far things get. You’ve never mentioned if the LED does anything.

Don’t forget that when you edit a rule file that has already spawned a timer that is still running, that timer will keep on running, but probably fail later because something in inaccessible, null.

Not a fix, a suggested diagnostic -

    rule "Network Router OFF"
    when
        Item Router changed to OFF
    then
        logInfo("network", "Router is offline")

        if(BlinkingTimer !== null){
            logInfo("network", "old timer " + BlinkingTimer.toString)
            BlinkingTimer.cancel()
            BlinkingTimer = null
        }
            // it's always null if we get this far
        BlinkingTimer = createTimer(now.plusSeconds(1), [ |
            logInfo("timer", "my handle is " + BlinkingTimer.toString)
             if(GPIO_OKLed.state == ON){
                 GPIO_OKLed.sendCommand(OFF)
             }else{
                 GPIO_OKLed.sendCommand(ON)
             }
             BlinkingTimer.reschedule(now.plusMillis(1000))
         ])
    end

Looking at OP’s items, the rule is started with Item Router changed to OFF, but there is no Router listed in items file only GPIO_OKLed and GPIO_WULed. This would explain the rule breaking before the timer?

rossko57 · November 24, 2019, 1:39pm

If there were no Item Router, it could never change, and the rule would never run at all.
In post one there is actually a Router Item, but we’ve been a long way round since then.

My point about both rule and the timer it spawns breaking, is that there is more than one rule execution involved.

I’m convinced this is all about the circular reference inside the timer block to its own handle. That isn’t a problem, until you mess with that handle. Typically by reloading the rules file.
That brings a thought - at load time, you should see in openhab.log "xxx.rules loaded" - do you see a multiple message for this file?

thanks all for helping .
GPIO_WULed is for other propose not listed here

the Router is listed above, I forgot to include here in the post , I’ve updated the post above

Try your group like below.

Group:Switch:AND(OFF,ON) Network <network>
Switch Router "Router" <network> (Network) { channel="network:pingdevice:Router:online" }
Switch InternetConnection "Internet Connection" <network> (Network) { channel="network:pingdevice:InternetConnection:online" }
