Simulation - cflurin/node-red-contrib-ramp-thermostat GitHub Wiki
This flow simulates the temperature trend depending on the profile and the time for a day period. It also uses the hysteresis setting to avoid frequently turning on/off.
Note: you need to install node-red-dashboard and node-red-contrib-dsm
The charts data are persistent, see also: Persist-chart-data-over-Node-Red-restart
