All data that is created gets stored in an Influx- DB on my Smarthome (https://hackaday.io/project/14862-diy-scada-smart-home) here you can see an example of opening the valves (after a long trip where nobody was at home). First the "open-signal" gets send (green-line) then the valves rotate and the response is received (yellow line). The response (state of the valve) is transmitted as an integer code: 1111 = no limit switch is triggered;  4444 = both limit switches are triggered; 2222 = open limit switch...; 3333 = closed limit switch... .
