i have one question, maybe i is an easy one, but actual i seem to stupid to do this.
My current project is a solar-logging with pimatic. I added a few devices and sensors and now this is working fine.
I am trying to “create” a new Device ( with a Graph ) how shows me the current solar charging in Watt.
To get Watt i need to multiply my volatge sensor with my ampere sensor. But i do not know how this is possible. For these two sensors i have to variables in pimatic.
I think it is simple - but how?!
Should be sth. like this $new.Wattage=$shell.volatge*$shell2.ampere
After that i need a “new device” with is connected to $new.Wattage
Thanks for every kind of help and sorry for the bad english!
