temp sensor keep on loging status switch

Dick

I have a working sensor that checks the temp om 2 places. If needed it wil switch on/of a Fan. That is all working perfect only this sensor logs continue the status of the switch. i am using Domoticz.
the log looks like this:

Does anyone know why it produce that large amount of logs?

flopp

The nodes send the data every 30 second, the log is ok.
You will get one line in the log very time a node report something.
It look like you also have an Event that gets trigger every time one of the nodes send data.

Dick

Yes you are right there is an Event. Do I have to add a timer or delay function in it or something else?

flopp

Depends on what you want to do with these temp/relay?

The log will still get all these lines even if you add a delay.

Dick

this sensor only messure the temp on 2 different locations and as seen in the Event, if the temp inside (TEMP binnen temp) <- 20 and the temp in the glasshouse is >-26 the fan switch on and the second part of the Event only switch of the Fan if the temp inside is to high (>-26) or the temp in the glasshouse is <-27. that is all I want with this project. I only want the mesurement every 15 min for example

flopp

Ok.

Then change Sleeptime to 900000, today you have 30000

900000 = 60000 * 15 minutes

Dick

that was easy, I do it right away. Thanks for the support and this stopped me for changing other parts of the event of the code of the sensor.
Have a nice day!

flopp

This is not a battery node, right?

Because this node never sleep, so it will consume battery all the time.

Dick

no good to mention, That is a new project for me to build an efficience battery powered node. In this case it is powered by an external power source.
