Trigger rule once in a period.

---

I would like to make a rule that does the following:

1. If the temp of sensor A is above 50 degreees for 30 seconds the switch SwitchA on
2. If the temp of sensor A is below 50 degreees for 30 seconds the switch SwitchA off

That’s easy and done.

Now here comes the challenge. If the rules above have not been triggered for 24 hours, then I would like to have SwitchA being switched on for 10 minutes and then switched off again. This way I can have my heating pump active only when needed, or once every 24 hours for 10 minutes (during days that the pump is not active)
But if the pump has been active for hours today, then the 10 minutes cycle is not needed…

Maybe this can be cut in two questions:

A: How can I have a rule being triggered every x hours? (answer could be, every day at 12:00h), I know…
B: How can I have a rule being triggered every x hours AFTER another rule was triggered…

Thanks (again) for your help!

if state of SwitchA was not updated for 1 day then switch on SwitchA for 10 minutes

@Heizelmann said:

if state of SwitchA was not updated for 1 day then switch on SwitchA for 10 minutes

This rule has one problem. If the pump is on for more then 24 hours (which might be possible) this rule switches it off. To correct this I tried:

if state of SwitchA was not updated for 1 day and Switch A is switched off then switch on SwitchA for 10 minutes

But this doesn’t work for me. The rule is still fired. Is this a bug? Of course I tested it with shorter periods of some seconds. `This is my test device:

   {
      "id": "Pump",
      "name": "Pump",
      "class": "ShellSwitch",
      "onCommand": "echo Pump on",
      "offCommand": "echo Pump off"
    }

And the rule is:

{
      "id": "pump-check",
      "name": "pump check",
      "rule": "if state of Pump was not updated for 30 seconds and Pump is off then switch on pump for 2 seconds",
      "active": true,
      "logging": true
    }

When the switch ‘Pump’ is turned by GUI or another Rule, this rule still fires after 30 seconds.

I will try it like this for a while:

{
“id”: “pumpswitchon”,
“name”: “pumpswitchon”,
“rule”: “if temperature of FloorHeating is greater than 21 for 30 seconds then switch switch2 on”,
“active”: true,
“logging”: true
},
{
“id”: “pumpswitchOff”,
“name”: “pumpswitchOff”,
“rule”: “if temperature of FloorHeating is less than 20 for 30 seconds and switch2 is turned on then switch switch2 off”,
“active”: true,
“logging”: true
},
{
“id”: “pumpinterval”,
“name”: “PumpInterval”,
“rule”: “if state of switch2 was not updated for 24 hours and switch2 is off then switch on switch2 for 10 minutes”,
“active”: true,
“logging”: true
}

@vanturenhout I can not see a difference in your last rule to my example. Did it realy work in case of that switch2 is on. For this case I expect that thee rule does NOT perform.

I made no difference, you’re right. But I couldn’t find a reason why it shouldn’t work.I was planning to have it go for a day or what and then see what happens. Will keep you posted.

From my side the problem is solved. In my example I used a ShellSwitch and I forgot the “getStateCommand”.

For testing use a DummySwitch instead and the rule

if state of SwitchA was not updated for 1 day and Switch A is switched off then switch on SwitchA for 10 minutes

works as expected. Sorry for the confusion.
