i'm using the dashboard with node-red since some weeks in combination with a much older FHEM installation. Step by step i would like to merge some functions from FHEM to Node-Red (or maybe ioBroker later on).
For my Heat-Control actually FHEM is the leading system and for the moment Node-Red should only do the dashboard-function with that.
To control the desired temperature i use the numeric ui-node. It is configured to change the output in 0.5 steps on every click. On FHEM side i controll a PID-device with it. Every time i click on the up- or down-button the new value is send out which is fine for Node-Red but not fine for FHEM.
I really would like to delay the output. So that if i would hit the up button 3 times to get from 20°C to 21.5°C it would just send the last value 21.5 and not every value between it.
I already tried to use the delay node but in my case it only put out the first value that is generated with the numeric node. I was not able to discard all values besides the last one with in 2sec for example.
