"Error: Value can not be set without dataPointPath"

[Ed1954]

Can you please post an example how to set the temperature. It doesn't work with or without the path "/operationModes/heating/setpoints/roomTemperature" it does not work. onOff and Mode can be changed.

here is an export of a function node I use. You could give it a try. You must replace AP12345 with you own (you can find it on your unit). The code could be simplified but it’s a start

Thank you for the fast answer, I i try to import i get following message. Parse error on line 7: ... = msg.topic.split("/");\n\nconst ssid = -----------------------^ Expecting 'EOF', '}', ':', ',', ']', got 'undefined'

Sorry for that. Could you paste the code below into an empty function node. Remember to replace DaikinAP12345 with you own

daikinMsg = { payload: payload, topic: "set" };
hasUpdateMsg = {payload: 'off', topic: 'DaikinAP12345/state/mode'}; }

Thank you very much, works perfect for me.
