I am new to Node-RED and have been playing with it for the last few days. I would like a few pointers as to how to proceed with my project. I have node-red installed on a raspberry pi. I have a client, broker, and dashboard all running on the Pi. Performance is good enough for what I am doing. I h…

Yes. If you import the flow (not sure you can the way I uploaded it) you can see I have a text node on the dashboard. I don't know what to enter in the Value format. Currently I have {{msg.payload}}. The Raspberry Pi command line client works fine. I issue the command: mosquitto_pub -t 'esp32/doo…

Subscribe to that topic and feed it straight into the text node

Do you mean have the button subscribe to that topic? Or an mqtt IN node?

I just noticed that if I request a switch status from the command line, the returned status DOES show up in the text node on the dashboard. Apparently the status button on the dashboard isn't configured properly to send the request message to the ESP32. If I press the status button on the dashboard…

I confirmed the status button is the problem. If I bring up the serial monitor on the ESP32 and click the status button the esp32/door/status message doesn't arrive at the ESP32. So how to get the status button to publish to the topic esp32/door/status??

Show us the command line you use to do it and export the flow consisting of the button to the mqtt out node and post that too. See this for how to post a flow [image] How to share code or flow json FAQs To share code samples or flow json in this forum, you need to take car…

The command line request is this: mosquitto_pub -t 'esp32/door/stat-return' -m 'null' This command will return the switch status to the command line and it also displays in the dashboard text node. Flow is attached. [{"id":"71994e9.b9a4fb","type":"tab","label":"ESP32 Flow","disabled":false,"info…

Success!! I found the problem. I needed to have two mqtt out nodes. One connects to the operate push button and the other one connects to the status push button. Once I did that, everything works as I want it to. The status now shows up on the dashboard when I click the status button. The Pi also re…

[image] rcbuck: Success!! I found the problem. I needed to have two mqtt out nodes. Almost certainly you don't. Post the flow you are using and I am sure it can be simplified. Just post the nodes from the buttons through to the mqtt nodes. [Edit] Out of interest, what software are you run…

I am running Arduino code on the esp32. I am using <PubSubClient.h> for the mqtt functions. I am monitoring two switches and triggering one relay. I am using it on my garage door opener. Sometimes I leave the house and wonder if I closed the door. With my cell phone I can connect through my firewall…
