How to trigger rule only once, until the condition becomes invalid and valid again

---

HI there,

I am looking for a way to trigger some emails from my temperature sensor. It should be an email like: “if T is below 20 then send email to…”. This works fine, but then it seems I get the emails all the time. What I want is that it sends the email only once, then waits until next time the T drops below 20. So I get warned only once if that happens.

How would I implement that? Anyone any ideas? Or am I overlooking something?

Is it possible to disable this rule and then have another rule that, when the T rises, enables it again?

Thanks!

@karlm261 you could try

if trigger T is below 20 then......

@karlm261 You can do it with an extra parameter.
So if T is below 20 and setonce = true then send email to and setonce = flase
The second rule to reset the parameter
if T is above 20 then setonce = true

Hi there, it still does not work. I have the two rules:

T drop below 19
if temperature of Heizung is less or equal than 19 and $heizung-min = “on” then send mail to “bla@bla” subject:“T ist leider bei 19 Grad!” text:“So ein Mist!” and set $heizung-min to “off” and set $heizung-max = “on”

T climbs above 21
if temperature of Heizung is greater or equal than 20 and heizung-max = “on” then send mail to “bla@bla” subject:“T hat 20 Grad erreicht!” text:“So ein Glück!” and set $heizung-min to “on” and set $heizung-max = “off”

But it does not work properly. What happens is that if the T drops below 19 I get both emails plenty of times for a while, until the T rises above 19.

What’s happening? Do I need to restart pimatic or so, when I change a rule?

@karlm261
there are some typos in your rules. did you copy pasted the rules or just written down here?

Tried to OCR them and then correct. Overlooked some typos. I will check the online version, too.

Ah, I think it should be {set “$xyz” to “off”} and not {set “$xyz” = “off”}!

@karlm261 You can better copy the rules from the pimatic configuration rather than OCR them. If you open the configuration in the pimatic web user interface change the view to “code” and search for “rules” (in my case I need to search it twice) to jump to the location where the rule entry start.

If you post
         code, configuration, or log file snippets please use three back-ticks (`) at the
beginning and the end of the snippet (use extra lines) to format it as a code block.

If you want to include a code elements as part of a sentence, use a single back-tick before and after element.

My rule I have used is:
If $XYZ = 1 and PIR reports present then set $XYZ = 0 and turn on Lamp

Second rule for reset:
If it is after 11 am then $XYZ = 1

$XYZ is a value
