Setpoint Actual value

Hi
I'm using SetPoints in dzVents to control heating in my home office, with the setpoint being used to specify my desired target temp.
I have a thermostat device that records the current/actual temp, and using this I decide whether to turn on/off a heater by a powered socket.
That all works fine.

In the Domoticz UI, when I click on the Setpoint to set the desired value, it shows the number with the up & down arrows so I can set the setpoint just fine. But to the left of that it says "Actual:" with a temperature of 7.0. No matter what I set the setpoint to, it always seems to say 7.0

What is this value supposed to represent? And how should I be updating it in dzVents?

Thanks

Hi
I do not have this problem on my stable version 2020.2.
If my setPoint device shows 20°C, when I click on it, the actual value is 20 and I can change the value with the arrows.

it represent the current setPoint. you can update a setPoint with the method updateSetPoint()

See the dzvents wiki for the additional parms depending on the kind of setpoint device.

Be careful using a switching socket on a heater.
A socket switches using a regular relais. When switching high currents (>10A), a relais will fail sooner or later by fusing the contacts (which will keep your heater on permanently).
A better solution is to use a solid-state-relais in between. So your socket switches the solidstate, and the solidstate controls the heater.
