Well, if the real room temperature is offset to the measurement at the radiators then simply setup this offset in the configuration of the radiators in the CCU2/Raspberrymatic and you are done
Thatās what @Multisaft7 did already. His experience was the same as mine. It didnāt work good enough.
@Multisaft7 is it possible to post your settings here? I also have 3 HM-Heating-Devices and 3 external Temepratur sensors (Jeelink). In FHEM it was possible to pair extenral temperature with internal HM-temperatureā¦
In Openhab I have big problems with Hotspots near the HM-Deviceā¦
I would like to but i did not find a useful solution for my problem
maybe we can use a skript, so we have to set a variable with set temperature, and a variable with fleixble control of Homematic device.
like (shematic code):
Variable Wunschtenmperatur = XY
`If (Wunschtemperatur- IST => 1)
Set Thermostat +1
If (Wunschtemperatur== IST)
Set Thermostat - 1
I am not sure if we can set the desired temperature in RaspberryMatic/CCU2?
like that?
switch (heizprofil_modus.state)
{
case 0: { // zu Hause
heizprofil_modus.postUpdate(0)
sendCommand(Temp_EG_Wz_set, 21)
sendCommand(Temp_EG_Bad_set, 21)
sendCommand(Temp_EG_Sz_set, 20)
sendTelegram(ābot1ā, āHeizprofil aktiviert: zu Hauseā)
Maybeā¦but my problem isā¦how i can set the offset of the radiators? Iāve got 3 Netatmo Devices which are measure the temperature in my roomsā¦and the offset depends on the weather outside so I often need to adjust the offset in the RaspberryMaticā¦So i have no idea how i can tell my Radiators the ārealā room temperature.
Hi,
I think its very complicated to get access to the internal controller of the heating device.
What you could do:
I have af floor heating at home, which takes at long time to heat up a room. I wasnāt satisfied with the temperatures, because it was often too hot. The heater heats until its reaches the desired temperature, afterwards itās hits temperatures at 2Ā°C above the desired temperature.
Iāve created a simple two point controller to control the room temperature:
rule "Homematic - Heizungsregelung - RT Bad"
when
Item Sensor_RT_Bad_2_SetTemperature changed or
Item Sensor_RT_Bad_2_ActualTemperature changed
then
var Number setTemp = Sensor_RT_Bad_2_SetTemperature.state as DecimalType
var Number curTemp = Sensor_RT_Bad_2_ActualTemperature.state as DecimalType
var Number AusHysterese = -0.5
var Number EinHysterese = 0.3
if ((setTemp - curTemp)>EinHysterese) {
if (Heizaktor_OG_4_State.state!=ON) Heizaktor_OG_4_State.sendCommand(ON)
} else if ((curTemp - setTemp)>AusHysterese) {
if (Heizaktor_OG_4_State.state!=OFF) Heizaktor_OG_4_State.sendCommand(OFF)
}
end
You could read the temperatures from you Netatmo devices and control the temperatures by varying the setTemperature

Does anybody knows how to read the temperature out of a new Netatmo Valve?
