I have a Broadlink Mini that I want to send three commands in a sequence (changing a channel on the TV).
The template node is to strip the msg.payload or else it gets merged with the next Home Assistant call service node.
This flow has an inject, template, delay and Home Assistant Call-Service nodes.
