rule does only work once with lua action

[Ronny H]

Hi

in my last question, i used a electric meter. Now i will convert this value always to a smaller value. This is not the problem. But i see that my defined condition in the rule only work once. I did not find the problem. Can anyone help me?

<objects>
  <object id="bigenergie" gad="1/6/216" type="29.xxx" init="persist">bigenergie</object>
  <object id="smallenergie" gad="1/6/218" type="EIS11" init="persist" forcewrite="true">smallenergie</object>
</objects>
<rules>
  <rule id="energy_convert">
    <condition type="object" id="bigenergie" trigger="true"/>
    <actionlist>
      <action type="script">
        value = tonumber(obj("bigenergie"));
        lowvalue = math.floor(value/1000);
        set("smallenergie", lowvalue);
      </action>
    </actionlist>
  </rule>
</rules>

In the logfile i can see only the first action of the rule:

1270471643 INFO KnxConnection : KnxConnection: Group socket opened. Waiting for messages.

Hi,

It's because the action is executed only when the condition changes from false to true. Since the condition you use will always evaluate to "true", the action is only executed once. That's one of the reasons why I added "stateless" rules in 0.0.1.27. If you use that version or a more recent one, you can add the parameter  type="if-true"  in the actionlist tag (the default is  type="on-true" ). With that parameter, the action will be executed every time the condition is evaluated to "true".

Hi

the parameter was the missed thing. It works now!

<actionlist type="if-true">...</actionlist>

Thanks!

hello hronny,

how it works:

<rules>
  <rule id="energy_convert">
  <condition type="object" id="bigenergie" trigger="true"/>
  <actionlist type="if-true">
  <action type="script">
     value = tonumber(obj("bigenergie"));
     lowvalue = math.floor(value/1000);
     set("smallenergie", lowvalue);
  </action>
  </actionlist>
  </rule>
</rules>
