Unable to Call hon.start_program from Node-RED (target issue) #192

Zoldex · 2025-03-03T13:20:38Z

🔹 Problem Summary:
I'm trying to call the hon.start_program service from Node-RED using the call service node in Home Assistant, but it doesn't work. The service call works fine when executed from the Developer Tools → Services in Home Assistant, but fails in Node-RED.

🔍 What I Tried:
Using Node-RED's call service node

Domain: hon
Service: start_program
Data:

{
    "target": {
        "device_id": "76e39483205b7192f766e317bf451265"
    },
    "parameters": {},
    "program": "eco"
}

Result: The debug output shows target: object empty, and the service is not executed.
Calling the service via Developer Tools
Tested the same JSON payload → ✅ Works correctly!
Calling via HTTP API using a function node in Node-RED

🛠 Expected Behavior:
I expect the hon.start_program service to be callable from Node-RED like any other Home Assistant service.

📌 Possible Causes:
Node-RED's call service node might not handle target.device_id correctly.
The hOn integration might require a different data structure for service calls in Node-RED.
❓ Questions:
Does hon.start_program support target.device_id in automation calls?
Is there a known workaround to make this work in Node-RED?
💡 Any help would be greatly appreciated! Thanks for your time and support. 🙌
