Thermostat setpoint support

[ArturK]

I have a few observations to support thermostats:

1. I have 2 Danfoss Living Connect thermostats in the same room (setup > more options > plans > roomplan).

When I change the value of one, the other also should change. This is because in the same room can have several radiators, thermostats, which should synchronize. It's done in the Danfoss Link panel (meanwhile, I'm using LUA scrip to do this).

2. In Blockly you can read the current setpoint value, but can be set only constant value. It is impossible to read the temperature from one thermostat and set the same on another.

3. In LUA should work dedicated command: commandArray [ 'SetSetpoint 147'] = '22.5'. It doesn't work, you need to use commandArray [ 'UpdateDevice'] = "147 | 0 | 22.5"

4. When I click the thermostat icon (menu > floorplan), a window appears with the graph. A window should appear to change the temperature (as in the utility menu).

5. In scenes I can't add Thermostat Setpoint. I would like to add for example ECO scene and set several thermostats to a lower temperature with one click.

Think that it should be commandArray['SetSetpoint:147'] = '22.5' - you missing the ":" and got a extra space in there

Agreed. It is a bit odd that you can only add switch devices into scenes and not devices like thermostats. It's such an obvious thing to want to do.
Unfortunately, nobody with the required programming skills has needed to scratch that particular itch

I can confirm the ArturK's observations.

Especially not being able to set thermostats (setpoints) in Blockly is hurting.
I can not even set it to constant values.
This should really be a standard function in a modern smarthome system.

My observation is, that blockly scripts are sometimes totally ignored by the system (Of course they are marked active)
or that single blockly commands are ignored (like the setpoint command).
In all these cases there is no message / no hint at all in the Log, why these blockly commands are ignored.

Is there any possibility to debug blockly on a deeper level than the system log, which doesn't show anything ?

I try to set the thermostat of a fridge and there ability to get negative values, as frigers get netgative values (-18 C in my case is the common temperature).
Can we get negative values on thermostat setpoint?

Hi

I have a similar situation:
- 1 x Devolo Home control thermostat
- 2 x Develo/Danfoss TRVs

When I change the setpoint on the thermostat, how do I pass the value to the TRVs? Or does it need to code this in LUA/dzVents?
Or can these be linked via the OZ network?

Thanks

Hello ArturK,

did you find a solution for your issue "4." (thermostat setpoint in floorplan)?

4. When I click the thermostat icon (menu > floorplan), a window appears with the graph. A window should appear to change the temperature (as in the utility menu).

This issue is also discussed in this thread https://www.domoticz.com/forum/viewtopi ... 34&t=13828 but it seems that there is no solution so far.
