9.3 Chrono: Chrono service for time scheduled event generation.






chrono



Chrono service for time scheduled event generation.
This service is useful to automate actions on a time based event scheduling. All the time programming of the scheduled events can be done through the browser on your Mobile or Tablet.
Typical applications are the control of the home heating system, the control of the garden watering, the control of the food feeding to the fish in the fishbowl and so on.
It is also possible to make the scheduled events dependent on external factors, as environment temperature, grass humidity etc. To make it possible it is needed to put sensors in the project and connect n some way them to the Chrono. Please refer to our project examples to understand how to make those connections.

For this version of Dome up to two seasons (summer and winter) are settable. For any season a complete set of timing configuration is available. The switching between seasons is manual.
If only one season is set, this control will act as enabling/disabling of the whole Chrono program.
If two seasons are set, you can manually switch among Disable, Summer program and Winter program.
