- Issue of the topic: I try to control my Tado Heating through a node-red Dashboard. But i can’t figure out how to send the value via mqtt to a whole group
Hello Community,
i have the following problem:
I’ve added my Tado Heating to Openhab and so far the control of the individual Thermostat is working fine. Even when i control a “HeatingGroup”, for examples all Thermostat in my House via Sitemap and BasicUI.
My Main Dashboard runs on Node-Red connected via MQTT. I can control a single item via MQTT without a problem. The problem is that i can’t send a command or state to a group. I’ll always get the following error in the openhab.log:
2018-10-07 12:16:43.293 [WARN ] [b.core.events.EventPublisherDelegate] - given new state is NULL, couldn’t post update for ‘gHeizungTest’
Node-Red send the new State of the Group to gHeizungTest. The Payload or MQTT Value is OFF or HEAT.
A single Item looks like this: (Here i can send OFF or HEAT without a problem and the item gets the new state)
String Wohnzimmer_Heizung_HVACModus "HVAC Modus" (gTado, gWohnzimmer, gHeizungTest) { channel="tado:zone:dbd1315d:1:hvacMode", mqtt=">[openhabmqtt:wohnung/wohnzimmer/heizung/get/hvacMode:state:*:DEFAULT]" }
My Group Items looks like
Group:String gHeizungTest (gTado) { mqtt=">[openhabmqtt:wohnung/alleraeume/heizung/get/hvacMode:state:*:DEFAULT],<[openhabmqtt:wohnung/alleraeume/heizung/set/hvacMode:state:DEFAULT]"}
I can control the Group via Sitemap and Basic UI without a Problem and set the Group to OFF or Heat. But i can’t do it via MQTT. I have the some Problem with other Groups.
Any Tipps to solve that Problem?
Greetings
Tobias
