Display total usage of a device between one on and off period

[SzilagyiR]

My goal is to display total usage of a device between one on and off period - basically need to know for how long this device was switched on. I’am wathing the device IP, if ping returns it’s on.

I found this topics, similar problem with mine, but I could not adapt the code, would somebody help me?

Rule to monitor device status ON/OFF and calculating total usage

Do you have persistence set up and running: https://www.openhab.org/docs/configuration/persistence.html And by usage do you mean that you want to count how many times the switch has flipped to ON? Or maybe see a graph indicating how long it has been ON for a period of time? I used the search function with “calculate time” and found this generator calculation thread. It’s old but it should get you started.

Measuring time of switch state

I have done the coding and tested it. I think it works right now. I include my solution here in case somebody would like to do the same in the future. My scenario is some sort pump which I want to monitor how much it runs. I think this is a good way of monitoring an automated process to make sure it is working correctly. I used this scenario to monitor my well pump for sprinklers. I just look at the run time in the morning to make sure it has done irrigation overnight. These are my items. Pump…

Rule for counting minutes state is on and persisting it

Hello all, I have an item boiler_status that gets updated once my boiler is powered on and off. I persist the change of the state but now I would like to measure the time the boiler is on and keep a total counter. I came up with the below to start with but I am confused right now and do not know if it going to work. In my items file I have Number boiler_counter Number boiler_counter_total Number mqtt_boiler_status “Boiler” { mqtt="<[has:/hab/heating/boilerStatus:state:default]" } and my…

Thanks!
