I have a Tasmota 8.2 client with 2 Relays here - connected to a local MQTT Server.
I can easily access the client via HTTP and it pushes all commands via MQTT to the MQTT Server.
I get all of these messages in Node-Red and can read and use it for different actions inside NR.
BUT ... I am not able to send the same command I can trigger by pressing the Web-Button on the HTTP-Device (turn ON / turn OFF) via Node-Red.
The MQTT message arrives at Node-Red in this format: topic: stat/PV_01_Front/POWER1 msg: ON
Unfortunately I cannot create the same message using the MQTT node, because all I can set is the TOPIC-parameter, but no message or text or anything.
Has someone already found a way to make this work ?
