Use a rule.

rule xxx
when
	Item thermostat1 changed
then
	thermostat2.postupdate(thermostat1.state)
end
3

Thanks, but VSC shows Error on postupdate and also sendcommand don´t work.
“The method sendcommand(State) is undefined for the type NumberItem”

4

If the items are type number

thermostat2.postupdate(thermostat1.state as DecimalType)
5

When i use postUpdate it works but i didn´t change the Value on Thermostat because i think i have to use SendCommand but this didn´t accept a state :frowning:

6

Sorry.

thermostat2.postUpdate(thermostat1.state as DecimalType)

or

thermostat2.sendCommand(thermostat1.state as DecimalType)

no Sorry, thanks for your help.

i get an Error by using this: Thermostat_EG_WZ_rechts_Soll.sendCommand(Tado_HEAT_target_temperature.state as DecimalType)

Ambiguous feature call.
The extension methods
sendCommand(Item, Command) in BusEvent and
sendCommand(Item, Number) in BusEvent
both match.

This is teted and works.

Number Tado_HEAT_target_temperature "t2[%s]"
Number Thermostat_EG_WZ_rechts_Soll "t1[%s]"

rule xxx
when
	Item Tado_HEAT_target_temperature changed
then
	Thermostat_EG_WZ_rechts_Soll.sendCommand(Tado_HEAT_target_temperature.state as DecimalType)
end

sitemap tmp label="TMP" {
    Setpoint item=Tado_HEAT_target_temperature
    Default  item=Thermostat_EG_WZ_rechts_Soll
}

Post you items please.

Now i get it working.

Items:
Number Tado_HEAT_target_temperature “Temperatur soll[%s]” { channel=“xxx” }
Number Thermostat_EG_WZ_rechts_Soll “Temperatur rechts [%s]” (Thermostat, Heizung_Wohnzimmer, EG_wohnzimmer) {channel=“xxx”}

Rule:
rule “Tado Wohnzimmer”

when
Item Tado_HEAT_target_temperature changed
then
Thermostat_EG_WZ_links_Soll.sendCommand(Tado_HEAT_target_temperature.state as Number)
Thermostat_EG_WZ_rechts_Soll.sendCommand(Tado_HEAT_target_temperature.state as Number)
end
