Hello all,  
I have an issue with a rule triggered after some time round about 2h.

I have an esp8266 dash button which send via mqtt a mesage to a item. If this item is changed it should trigger a rule but after around 2 hours silence of this button the item is changed but the rule is not triggered

here is the code

```csv
MQTT
Thing mqtt:topic:button (mqtt:broker:mosquitto) {
Type string : JSONstate_value "JSONstate_value" [stateTopic="button/state/json", transformationPattern="JSONPATH:$.value"]
}

String	string_button_statejsonvalue "button JSON State Value" <mobile> {channel="mqtt:topic:button:JSONstate_value"}

rule "Handle button"
when
    Item string_button_statejsonvalue changed
then

```

is there a better way or any issues with my code???

Can you show us that in your `events,log` ?  
What un-changed the Item from a previous button press?

How do you know?  
The rule shown is incomplete.  
Does your rules file load? (look in your `openhab.log`)

</div>

attached the log

```csv
2020-06-03 16:00:51.992 [vent.ItemStateChangedEvent] - string_button_statejson changed from {"event":"p[6].b[4].val", "value":0} to {"event":"p[6].b[4]", "value":"ON"}

2020-06-03 16:00:51.994 [vent.ItemStateChangedEvent] - string_button_statejsonvalue changed from 0 to ON

```

and the rule

```csv
rule "Handle Master"
when
    Item string_button_statejsonvalue changed
then
    logInfo ("Handle ", "triggerd")
    //parse out data from JSON string (page, button, value)
    var String eventpage = string_button_statejsonevent.state.toString.split("\\[").get(1).split("\\]").get(0)
    var String eventbutton = string_button_statejsonevent.state.toString.split("\\[").get(2).split("\\]").get(0)
end

```

the loginfo is not written that’s why i know it is not triggerd

Have you ensured the rle “name” is unique across all your rules files?

Unless you have some other very badly behaved rules hogging all the execution threads, there’s nothing wrong. You’ve missed something somewhere.

Make yourself another rule as well

```php
rule "Extra diagnostic"
when
    Item string_button_statejsonvalue changed
then
    logInfo ("diag", "triggered")
end

```

After editing, look in your `openhab.log` for a rules file refreshed message.

Okay, that does sound like you’ve got other rules blocking new rule starts.

Easy way probably to disable other rules by renaming files xxx.rules to xxx.rules.bak or something. You’d then need to restart openHAB to kill any rules already running and looping.

Only if you want to eliminate them as suspects.

> @milo To to summarize, you’re getting a delay on actions/rules processing…not just on the 1st time a rule runs, but intermittently after the rule hasnt been run e.g. the system has been booted for 24+ hours… the rule you are experiencing the delay with HAS been run before in that 24 hours… but now its being slow/delayed again? If thats what you’re experiencing, obviously there are a ton of variables involved e.g. have you a massive rule-set etc… but for the purposes of this reply, Ill just ass…
