I am trying to set up an automation that among other things will turn off my heat pump using a Broadlink RM4 Pro. In Developer Tools/Services I taught the Broadlink the correct turn_off command and using Remote:Send command I can successfully turn the heat pump off.

In Node Red I have used a call service node triggered by an inject node. The settings for the call service node are as follows....

Domain = remote

Service = send_command

Entity id = remote.rm_pro_remote

Data = power_off

When I run this I get an error message in debug that says "Call-service error. required key not provided @ data['command']"

Can anyone tell me where I am going wrong with this? Thanks.

I'm supposed to respect my elders, but it's getting harder and harder for me to find one now.

Sounds to me like you're missing an authentication key. I don't see that in the data you are passing. Is there maybe a config node?

I am sure there are users with Node Red knowledge who can help - although I use a RM4 Pro with HA to control my heatpump (and blinds, projector screen, stereo etc), I have just done so by assigning a number of virtual switches under the standard HA framework, which I assume isn't that helpful for you, but feel free let me know otherwise.

Sorry, I am already at the outer limits of my understanding of Node Red. Where would I look for the key? Thanks.

I assume you have used the wiki info to test obtaining and transmitting codes with node red? (https://www.home-assistant.io/integrations/broadlink/#using-node-red-to-obtain-codes)

that's your issue, I think. rather than passing a string to the "Data" field (ie "TURN_OFF"), you have to send a JSON object with a "command" property: { "command": "TURN_OFF" }

Move to New Zealand's best fibre broadband service (affiliate link). Note that to use Quic Broadband you must be comfortable with configuring your own router.
