I recently created a show case for playing with the Relay actions.
My device was registered on Cloud der Dinge of Deutsche Telekom before, but I want to move it to the test tenant (tarent.eu-latest.cumulocity.com).
As the device will set a relay state I used the relay widget in the Cockpit app and tied it to the device.
- When I click the switch in the dashboard it is closed and the power of the peripheral is on
- When I click the switch again, the relay is opened and the power of the peripheral is off
I can switch power on (close the relay), but opening the relay is not working - it creates the same operation like closing.
So I can not switch power off again.
I checked the operations per REST API and saw that it seems to create the exactly same operation like closing the relay.
