Switching from One heating system to another

[Patricen]

Hello guys,

I do have both an air conditioning system (that makes heat during winter!) + hot water radiators.
Hot water radiators are controlled using popp thermostatic radiator valves, basically a setpoint and temperature readback with embedded regulation.

I would like to make two scenes depending if I like to use the aircon or radiator without having to program one schedule on each setpoint (aircon + radiator).

The idea I have is to have a room setpoint (scheduled), and depending from a switch position activate either the radiator, transmitting the scheduled room setpoint to the thermostat, or activate the aircon using the room setpoint schedule.

Is there an easy way using Blockly & scenes or groups, or a harder one using dzVents? (As you can mention, I'm not so familiar with programming, but I'm trying to become...)

Cold sunday, then tried Domoticz dzVents coding, but still not skilled, I did not succeed...

I have set :
- a two level switch that switches gas heating or heatpump
- a master setpoint for the room temperature

When gas is selected, I would like to give the hot water radiator setpoint the value from the master setpoint.
When heatpump is selected, I would like to set the heatpump on, heating mode and give the heatpump setpoint the value of the master setpoint (I'm using Melclout Python plugin from Gysmo38, then I need to round the setpoint as the heatpump only accepts integer values, and arrange setpoint to level values (0% = 16%, 10%=17°... 150%=31°).

Easy to say, but not really to code for me, can somebody help?
