LCD module on Node-RED

Hi, it is possible control LCD module from Node-RED? I am trying use examples from https://www.bigclown.com/doc/interfaces/mqtt-topics/, but does not work. thanks

Hello, you need to use one of the firmwares bcf-generic-node-power-module.
This firmware supports and detects almost all sensors and modules. It also keeps the radio listening for MQTT commands to control display, LED strip and relay on power module. This is not low power firmware so we suggest powering it from USB or Power Module.

thank, now it is working.

Now I have problem with sending multiple text in same time, can I send more text in one command? If I send text in more MQTT topics in short time some text is not shown. thanks

Hello,

unfortunately you can send one text command in one mqtt/radio packet. For sending more text commands, please use the delayblock in Node-RED to give some delay between messages.
