Node-RED beginner

[benoitdudu]

Hi,

I am new to node-red so I probably do not understand how it should work. I would like to use node-red-contrib-rfxcom for my MCZ pellet stove. I saw that another 'benoit' reached to use it... it appear that having the same first name is not enough.

Currently my flow consists of:

• an inject node, where I set the 'Payload' and the 'Topic' fields as follow. Payload: it is a JSON string { "id": "0xe8e074", "type": "rfx-heat", "beep": false, "fanSpeed": [ 1, 1, 6 ], "flamePower": 1, "mode": 1 } Topic: MCZ_PELLET_STOVE_2_FAN
• rfx-heat-out: Serial Port: COM5 Address: get address from message topic Name: titi rfx-heat

The output of my 'inject' node is connected to the input of the 'rfx-heat-out' node.

When I delpoy my flow, I get the following messages that tell me the connection is OK: 17 Aug 09:56:04 - [info] Stopping flows 17 Aug 09:56:04 - [rfxcom] on COM5 - Cleared command message queue 17 Aug 09:56:04 - [info] Stopped flows 17 Aug 09:56:04 - [info] Starting flows 17 Aug 09:56:04 - [info] Started flows 17 Aug 09:56:04 - [info] [rfx-heat-out:titi rfx-heat] connecting to COM5 17 Aug 09:56:09 - [rfxcom] on COM5 - Sent : 0D,00,00,00,00,00,00,00,00,00,00,00,00,00 17 Aug 09:56:10 - [rfxcom] on COM5 - Sent : 0D,00,00,01,02,00,00,00,00,00,00,00,00,00 17 Aug 09:56:10 - [rfxcom] on COM5 - Received: 14,01,00,01,02,5F,22,00,00,00,40,03,00,1C,10,5E,46,58,43,4F,4D 17 Aug 09:56:10 - [rfxcom] on COM5 - Sent : 0D,00,00,02,07,00,00,00,00,00,00,00,00,00 17 Aug 09:56:10 - [rfxcom] on COM5 - Received: 14,01,07,02,07,43,6F,70,79,72,69,67,68,74,20,52,46,58,43,4F,4D 17 Aug 09:56:10 - [rfxcom] on COM5 - Copyright RFXCOM 17 Aug 09:56:10 - [rfxcom] on COM5 - Started command message queue 17 Aug 09:56:10 - [info] [rfx-heat-out:titi rfx-heat] connected: Serial port COM5

But when I click on the 'inject' node I get a message: 17 Aug 10:07:50 - [warn] [rfx-heat-out:titi rfx-heat] Error: Invalid deviceId format

What do I miss? How to define a correct deviceId?

Best Regards, Benoît

Hi again,

After several tries I modifed my 'inject' node as follow: { "beep": false, "fanSpeed": [ 1, 1, 6 ], "flamePower": 1, "mode": 1 } And the 'rfx-heat-out' as follow: Serial Port: COM5 Address: send all command to the same address MCZ_PELLET_STOVE_2_FAN/0x123456 Name: titi rfx-heat

This seems better. It is currently a bit hot to check it.

Thank you for providing us this feature.

Yeah, the ID or 'address' always forms part of the message topic - this is universal throughout node-red-contrib-rfxcom
